Binance P2P Trading Skill
Help users interact with Binance P2P (C2C) via natural-language queries.
When to Use / When NOT to Use
Use this skill when the user wants to:
- Check P2P buy/sell quotes for a crypto/fiat pair (e.g., USDT/CNY).
- Search P2P advertisements and filter by payment method(s), limits, merchant quality.
- Compare prices across payment methods (e.g., Alipay vs bank transfer).
- View their own P2P order history / summary (requires API key).
- Query order detail and view full order timeline (requires API key).
- Check appeal/complaint status and view complaint history (requires API key).
- Submit evidence for an existing appeal (upload files + submit description) (requires API key).
- View complaint process timeline (flow of actions, CS notes, evidence) (requires API key).
- Cancel an existing appeal (withdraw complaint, irreversible) (requires API key).
- View available complaint reasons for an order (requires API key).
- Publish, update, or manage P2P advertisements (requires API key + merchant permission).
- View merchant profiles and their ad listings (requires API key).
- Query supported digital and fiat currencies (requires API key).
Do NOT use this skill when the user asks about:
- Spot/Convert prices, futures/derivatives, margin, trading bots.
- Deposits/withdrawals, wallet transfers, on-chain transactions.
- Creating/cancelling orders, releasing coins (trading operations). Cancelling appeals (complaints) IS supported.
- Initiating new appeals (submit-complaint is deferred; evidence supplement for existing appeals IS supported).
- Sending chat messages in order conversations.
Ask clarifying questions (do not guess) if any key inputs are missing:
fiat (e.g., CNY)asset (e.g., USDT)- user intent: buy crypto or sell crypto
- preferred payment method(s)
- target amount (optional but recommended for ad filtering)
Core Concepts
tradeType mapping (avoid ambiguity)
- User wants to buy crypto (pay fiat, receive USDT/BTC) →
tradeType=BUY
- User wants to sell crypto (receive fiat, pay USDT/BTC) →
tradeType=SELL
Always reflect this mapping in responses when the user's wording is ambiguous.

Environment Configuration
Base URLs (production)
| Logical Name | URL |
|---|
SAPI_BASE | https://api.binance.com |
MGS_BASE | https://www.binance.com |
C2C_WEB | https://c2c.binance.com |
Implementation hint (for code generation)
When the skill generates curl / Python / JS code, use these fixed base URLs:
import os
SAPI_BASE = "https://api.binance.com"
MGS_BASE = "https://www.binance.com"
C2C_WEB = "https://c2c.binance.com"
def common_headers(api_key: str) -> dict:
return {
"X-MBX-APIKEY": api_key,
"User-Agent": "binance-wallet/1.0.0 (Skill)",
}
SAPI_BASE="https://api.binance.com"
MGS_BASE="https://www.binance.com"
C2C_WEB="https://c2c.binance.com"
Note: SAPI signing uses HMAC SHA256, no param sorting required.
Security & Privacy Rules
Credentials
- Required env vars:
BINANCE_API_KEY (sent as header)BINANCE_SECRET_KEY (used for signing)
Never display full secrets
- API Key: show first 5 + last 4 characters:
abc12...z789
- Secret Key: always mask; show only last 5:
***...c123
Permission minimization
- Binance API permissions: Enable Reading only (Phase 1/2).
- Phase 3 ad management additionally needs write permissions.
- Do NOT request/encourage withdrawal or modification permissions beyond what's needed.
Storage guidance
- Prefer environment injection (session/runtime env vars) over writing to disk.
- Only write to
.env if the user explicitly agrees.
- Ensure
.env is in .gitignore before saving.
⚠️ CRITICAL: SAPI Signing (Different from Standard Binance API)
Parameter ordering
- DO NOT sort parameters for SAPI requests.
- Keep original insertion order when building the query string.
Example:
params = {"page": 1, "rows": 20, "timestamp": 1710460800000}
query_string = urlencode(params)
query_string = urlencode(sorted(params.items()))
Signing details
See: references/authentication.md for:
- RFC 3986 percent-encoding
- HMAC SHA256 signing process
- Required headers (incl. User-Agent)
- SAPI-specific parameter ordering
API Overview
Public Queries (MGS C2C Agent API — No Auth)
Base URL: https://www.binance.com
| Endpoint | Method | Params | Usage |
|---|
/bapi/c2c/v1/public/c2c/agent/quote-price | GET | fiat, asset, tradeType | Quick price quote |
/bapi/c2c/v1/public/c2c/agent/ad-list | GET | fiat, asset, tradeType, limit, order, tradeMethodIdentifiers | Search ads |
/bapi/c2c/v1/public/c2c/agent/trade-methods | GET | fiat | Payment methods |
Parameter notes:
tradeType: BUY or SELL (treat as case-insensitive)limit: 1–20 (default 10)tradeMethodIdentifiers: pass as a plain string (not JSON array) — e.g. tradeMethodIdentifiers=BANK or tradeMethodIdentifiers=WECHAT. Values must use the identifier field returned by the trade-methods endpoint (see workflow below). ⚠️ Do NOT use JSON array syntax like ["BANK"] — it will return empty results.
Workflow: Compare Prices by Payment Method
When the user wants to compare prices across payment methods (e.g., "Alipay vs WeChat"), follow this two-step flow:
Step 1 — Call trade-methods to get the correct identifiers for the target fiat:
GET /bapi/c2c/v1/public/c2c/agent/trade-methods?fiat=CNY
→ [{"identifier":"ALIPAY",...}, {"identifier":"WECHAT",...}, {"identifier":"BANK",...}]
Step 2 — Pass the identifier as a plain string into ad-list via tradeMethodIdentifiers, one payment method per request, then compare:
GET /bapi/c2c/v1/public/c2c/agent/ad-list?fiat=CNY&asset=USDT&tradeType=BUY&limit=5&tradeMethodIdentifiers=ALIPAY&tradeMethodIdentifiers=WECHAT
Compare the best price from each result set.
Important: Do not hardcode identifier values like "Alipay" or "BANK". Always call trade-methods first to get the exact identifier strings for the given fiat currency.
Personal Orders (Binance SAPI — Requires Auth)
Base URL: https://api.binance.com
| Endpoint | Method | Auth | Usage |
|---|
/sapi/v1/c2c/orderMatch/listUserOrderHistory | GET | Yes | Order history |
/sapi/v1/c2c/orderMatch/getUserOrderSummary | GET | Yes | User statistics |
Authentication requirements:
- Header:
X-MBX-APIKEY
- Query:
timestamp + signature
- Header:
User-Agent: binance-wallet/1.0.0 (Skill)
Output Format Guidelines
Price quote
- Show both sides when available (best buy / best sell).
- Use fiat symbol and 2-decimal formatting.
Example:
USDT/CNY (P2P)
- Buy USDT (you buy crypto): ¥7.20
- Sell USDT (you sell crypto): ¥7.18
Ad list
Return Top N items with a stable schema:
- adNo (ad number / identifier)
- price (fiat)
- merchant name
- completion rate
- limits
- payment methods (identifiers)
Avoid generating parameterized external URLs unless the API returns them.
Placing orders (when user requests):
-
This skill does NOT support automated order placement.
-
When user wants to place an order, provide a direct link to the specific ad using the adNo:
https://c2c.binance.com/en/adv?code={adNo}
{adNo}: the ad number/identifier from the ad list result
Example: https://c2c.binance.com/en/adv?code=123
-
This opens the specific ad detail page where user can place order directly with the selected advertisement.
Personal orders
- Time format:
YYYY-MM-DD HH:mm (UTC+0) — always display in UTC timezone
- Include: type, asset/fiat, amount, total, status
- Provide a brief summary line (count + totals) when filtering
Time field conversion (for createTime in listUserOrderHistory):
- The
createTime field returns a Unix timestamp in milliseconds (13 digits).
- Convert to human-readable format in UTC+0 timezone:
# Python example
from datetime import datetime, timezone
readable_time = datetime.fromtimestamp(createTime / 1000, tz=timezone.utc).strftime('%Y-%m-%d %H:%M (UTC+0)')
# JavaScript example
const readableTime = new Date(createTime).toISOString().replace('T', ' ').slice(0, 16) + ' (UTC+0)';
// Or more explicitly:
const date = new Date(createTime);
const readableTime = date.getUTCFullYear() + '-' +
String(date.getUTCMonth() + 1).padStart(2, '0') + '-' +
String(date.getUTCDate()).padStart(2, '0') + ' ' +
String(date.getUTCHours()).padStart(2, '0') + ':' +
String(date.getUTCMinutes()).padStart(2, '0') + ' (UTC+0)';
- Always display the converted time to users with timezone info, not the raw timestamp.
Error Handling (User-Facing)
- Invalid API key (-2015): prompt to verify
.env / API Management.
- Signature failed (-1022): warn about wrong secret, sorted params, or stale timestamp.
- Timestamp invalid (-1021): advise time sync / regenerate timestamp.
- Rate limit: ask to retry later.
Limitations (By Design)
This skill does NOT:
- Place/cancel orders
- Mark as paid / release coins
- Initiate new appeals / submit-complaint (only evidence supplement for existing appeals is supported)
- Post/modify advertisements (Phase 1/2 only — Phase 3 adds ad management for merchants)
- Expose sensitive order-detail endpoints beyond what's needed for history/summary
For in-app actions, guide users to the official P2P orders page (only as a general entry point).
Developer Notes
Version Check (First Invocation per Conversation)
On the first invocation of this skill per conversation, call:
GET /bapi/c2c/v1/public/c2c/agent/check-version?version=2.0.0 (Base: https://www.binance.com)
Behavior:
- If
needUpdate=true: show: New version of P2P Skill is available (current: {clientVersion}, latest: {latestVersion}), update recommended.
- Else / on failure: proceed silently.
Client-side operations
- Asset filtering: if API doesn't support it, fetch then filter locally.
- Aggregations: compute totals client-side when summary endpoint is insufficient.
Phase 3 — Order & Appeal + Ad Publish & Management
Phase 3 extends the skill from read-only market/order queries to write operations (ad management) and advanced order workflows (order detail, appeal/complaint tracking).
Phase 3 Design Constraints
| Constraint | Details |
|---|
| Authentication | All Phase 3 features require API Key + Secret Key |
| Write-op confirmation | Any write operation (publish ad, update ad, change status) must show an operation summary and get explicit user confirmation before executing |
| API Key permissions | Phase 1 only needed "Enable Reading"; Phase 3 additionally needs write permissions for ad management |
| Privacy masking | Never display counterparty sensitive info (bank card, Alipay account, phone, email, real name) or internal IDs (payId). Even if the API returns these fields, filter them out in user-facing output. For payment methods, show only tradeMethodName (e.g. "支付宝") |
Scene 1: Order Query & Appeal Handling
1.1 Query Order Detail
Trigger examples:
- "查看订单 20260315123456 的详情"
- "我最近那笔 USDT 买入订单怎么样了？"
- "帮我查一下这个订单号"
- "Show me the details of order 20260315123456"
Behavior:
- If user provides an order number → call
getUserOrderDetail
- If user describes an order vaguely → call
listOrders with filters, then let user pick
- Based on order status, branch:
Status branch handling:
| Status | Action |
|---|
| Completed (4) | Show full timeline (create → pay → confirm → complete), finish |
| Cancelled (6) / Expired (7) | Show cancel reason (timeout / manual / system), finish |
| In Progress (1=Unpaid, 2=Paid, 3=Releasing) | Show current step + countdown timers |
| In Appeal (5) | Auto-enter 1.2 — show appeal status |
Output format (Order Detail):
📋 Order No: {orderNumber}
├─ Type: {tradeType} {asset}
├─ Amount: {amount} {asset} @ {price} {fiatUnit}
├─ Total: {fiatSymbol}{totalPrice}
├─ Status: {orderStatus description}
├─ Counterparty: {buyerNickname / sellerNickname}
├─ Created: {createTime in UTC+0}
│
├─ Timeline:
│ ├─ Created: {createTime}
│ ├─ Paid: {notifyPayTime or "—"}
│ ├─ Confirmed: {confirmPayTime or "—"}
│ └─ Cancelled: {cancelTime or "—"}
│
├─ Commission: maker {commissionRate}% = {commission} {asset}
│ taker {takerCommissionRate}% = {takerCommission} {asset}
└─ Complaint: {isComplaintAllowed ? "Allowed" : "Not Allowed"} | Status: {complaintStatus or "None"}
Countdown display (for in-progress orders):
- If status=1 (Unpaid): show "Payment deadline: {notifyPayEndTime}" with remaining time
- If status=2 (Paid): show "Release deadline: {confirmPayEndTime}" with remaining time
1.2 View Appeal / Complaint Status
Trigger:
- Automatically when order status = In Appeal (5)
- "这个申诉进展到哪了？"
- "订单 20260315123456 的申诉怎么样了？"
- "What's the appeal status?"
Behavior:
- Call
query-complaints with the order number
- Display complaint info in structured format
Output format:
⚠️ Appeal Status for Order {orderNo}
├─ Complaint No: {complaintNo}
├─ Status: {complaintStatus description}
├─ Role: {roleIdentity} (COMPLAINANT / RESPONDENT)
├─ Reason: {reason}
├─ Created: {complaintCreateTime}
├─ Order Asset: {orderAsset} | Fiat: {orderFiat}
├─ Order Amount: {orderAmount} ({fiatSymbol})
├─ Amount in USDT: {orderAmountInUsdt}
└─ Dispute Amount: {disputeAmount}
Follow-up guidance (append after the status block, based on complaintStatus):
| complaintStatus | Guidance to show |
|---|
| 0 (Respondent Processing) | "Waiting for the counterparty to respond. You will be notified when there is an update." |
| 1 (Complainant Processing) | "⚡ Action needed — you need to provide evidence or respond. Say "submit evidence for order {orderNo}" to upload proof now." |
| 2 (CS Processing) | "💡 Both parties may still submit evidence at this stage. You can submit evidence directly through this skill — say "submit evidence for order {orderNo}" or "提交证据" to upload payment proof, screenshots, or other supporting documents." |
| 3 (Completed) | "This appeal has been resolved." |
| 4 (Cancelled) | "This appeal has been cancelled." |
MUST follow: When complaintStatus is 0, 1, or 2 (appeal still active), NEVER tell the user to "go to the app" or "head to the dispute center". Always guide them to use this skill to submit evidence. The skill supports the full evidence upload flow (Scene 1.5).
Complaint status mapping:
| Status Code | Display Name | Description |
|---|
| 0 | Respondent Processing (被申诉人处理中) | Complaint initiated, waiting for counterparty to respond |
| 1 | Complainant Processing (申诉人处理中) | Waiting for complainant to provide evidence or take action |
| 2 | CS Processing (客服处理中) | Customer service reviewing; both parties may submit evidence |
| 3 | Completed (已完成) | Appeal resolved |
| 4 | Complaint Cancelled (申诉取消) | Appeal withdrawn |
Important: Do NOT confuse these with orderStatus codes — they are separate enums.
When complaintStatus=2 (CS Processing), the user should be guided to submit evidence if needed; do NOT tell them to "wait for counterparty".
1.3 Complaint History Query
Trigger:
- "查看我的所有申诉记录"
- "最近3个月有哪些申诉？"
- "List my complaints as complainant"
Behavior:
- Call
query-complaints with optional filters (roleIdentity, status, date range)
- Default: last 90 days if no date specified
- Show paginated results
Output format:
📋 Complaint Records (Total: {total})
┌───────────┬──────────────┬──────────┬────────┬───────────────┐
│ Order No │ Complaint No │ Status │ Role │ Created │
├───────────┼──────────────┼──────────┼────────┼───────────────┤
│ {orderNo} │ {no} │ {status} │ {role} │ {time UTC+0} │
└───────────┴──────────────┴──────────┴────────┴───────────────┘
1.4 Order List & History
Trigger:
- "查看我的订单列表"
- "最近的 USDT 买入订单"
- "Show my completed orders this week"
Behavior:
- For active/recent orders → use
listOrders (richer filter: advNo, status, payType)
- For historical orders → use
listUserOrderHistory (supports tradeType, date range)
Output format (Order List):
📋 Orders (Page {page}, Total: {total})
┌──────────────┬──────┬───────┬──────────────┬────────┬───────────────┐
│ Order No │ Type │ Asset │ Total │ Status │ Created │
├──────────────┼──────┼───────┼──────────────┼────────┼───────────────┤
│ {orderNo} │ BUY │ USDT │ ¥{totalPrice}│ 已完成 │ {time UTC+0} │
└──────────────┴──────┴───────┴──────────────┴────────┴───────────────┘
Order status code mapping:
| Code | Name | Chinese |
|---|
| 0 | Pending | 处理中 |
| 1 | Unpaid | 未付款 |
| 2 | Paid (Unconfirmed) | 已付款 |
| 3 | Releasing | 放币处理中 |
| 4 | Completed | 已完成 |
| 5 | In Appeal | 申诉中 |
| 6 | Cancelled | 已取消 |
| 7 | Expired (System Cancel) | 超时取消 |
1.5 Submit Appeal Evidence
Trigger:
- "帮我上传这个截图作为申诉证据"
- "我要提交付款凭证"
- "Submit evidence for order 228..."
- "Upload proof of payment for my appeal"
- Automatically suggested when order is in Appeal (status=5) and
complaintStatus=2 (CS Processing)
Behavior (3-step flow):
Step 1 — Get presigned upload URL:
GET /sapi/v1/c2c/agent/file-upload/get-s3-presigned-url?fileName=proof.jpg&scenario=complaint
→ { "uploadUrl": "https://s3...presigned...", "filePath": "/client_upload/c2c/complaint/..." }
Step 2 — Upload file to S3:
curl -X PUT -T /path/to/local/file.jpg "{uploadUrl}"
The presigned URL is valid for 5 minutes. Upload must complete within this window.
Step 3 — Submit evidence to SAPI:
POST /sapi/v1/c2c/agent/complaint/submit-evidence
Body: { "orderNo": "228...", "description": "付款截图", "fileUrls": ["/client_upload/c2c/complaint/..."] }
→ { "data": true }
Supported file types:
txt, doc, xls, docx, xlsx, jpg, jpeg, png, pdf, mp3, mp4, avi, rm, rmvb, mov, wmv
Output format (Upload Progress):
📤 Evidence Upload for Order {orderNo}
├─ Step 1/3: Getting upload URL... ✅
├─ Step 2/3: Uploading file "{fileName}"... ✅
├─ Step 3/3: Submitting evidence...
│ ├─ Description: {description}
│ └─ Files: {n} file(s)
└─ Result: ✅ Evidence submitted successfully
💡 Tip: You can submit additional evidence by saying "再上传一个文件"
Output format (Failure):
❌ Evidence Upload Failed
├─ Step: {which step failed}
├─ Error: {error message}
└─ Suggestion: {actionable fix}
Common errors:
Unsupported file type → Check file extension; see supported types abovePresigned URL expired → Re-request upload URL (Step 1)Order not in appeal → Evidence can only be submitted for orders with active complaintsFile too large → Reduce file size or split into multiple files
Write-op confirmation rule:
Evidence submission follows the same confirmation protocol as Scene 2 write operations:
- Show a summary of what will be submitted (file name, description, order number)
- Wait for user to confirm before executing Step 3
Confirmation format:
📋 Evidence Submission Summary
├─ Order: {orderNo}
├─ Description: {description}
├─ Files to submit:
│ 1. {fileName1} ({fileType}, uploaded ✅)
│ 2. {fileName2} ({fileType}, uploaded ✅)
└─ ⚠️ Confirm submission? (reply "确认" or "confirm")
1.6 View Complaint Process Timeline
Trigger:
- "查看申诉的处理流程"
- "这个申诉经历了哪些步骤？"
- "Show complaint timeline for order 228..."
- "What happened in the appeal process?"
Behavior:
- Call
get-complaint-flows with orderNo (and optionally complaintNo)
- Display chronological timeline of all process steps
Output format:
📜 Complaint Timeline: Order {orderNo} (Complaint #{complaintNo})
│
├─ [{createTime}] {creatorNickName}
│ ├─ Type: {infoType description}
│ ├─ Description: {description}

│ ├─ Remark: {remark}
│ └─ Evidence: {fileUrls or "None"}
│
└─ ... (chronological order)
💡 Actions: "提交证据" to submit evidence | "刷新" to check for updates
Info type mapping (for display):
| infoType | Description |
|---|
| 1 | Complaint Initiated |
| 2 | Evidence Submitted |
| 3 | CS Review Note |
| 4 | Resolution / Decision |
Note: fileUrls in the response are CDN-assembled URLs that can be directly accessed.
remarkHtml takes precedence over remark when available for rendering.
1.7 Cancel Complaint / Appeal
Trigger:
- "取消这个申诉"
- "我不想继续申诉了"
- "Cancel my appeal for order 228..."
- "Withdraw my complaint"
⚠️ This is a DESTRUCTIVE action — mandatory confirmation required!
Cancelling an appeal is irreversible. The user forfeits their dispute and the order proceeds to its normal resolution. The agent MUST follow this strict confirmation protocol:
Behavior:
- When user expresses intent to cancel, FIRST show a clear warning
- Wait for explicit confirmation ("确认取消" / "confirm cancel" / "yes")
- Only then call
cancel-complaint with the orderNo
- Display the result
Warning format (MUST show before executing):
⚠️ Cancel Appeal Confirmation
├─ Order: {orderNo}
├─ Current complaint status: {status from previous query if available}
│
╔══════════════════════════════════════════════╗
║ WARNING: This action CANNOT be undone! ║
║ - Your appeal will be permanently withdrawn ║
║ - You will lose the right to dispute this ║
║ order through the appeal process ║
║ - The order will proceed to normal ║
║ resolution without CS intervention ║
╚══════════════════════════════════════════════╝
│
└─ Reply "确认取消" or "confirm cancel" to proceed
On success:
✅ Appeal Cancelled
├─ Order: {orderNo}
├─ Status: Appeal withdrawn
└─ The order will now proceed to normal resolution.
On failure:
❌ Cancel Failed
├─ Order: {orderNo}
├─ Reason: {error message}
└─ Possible causes: no active appeal, order already resolved, or insufficient permissions.
MUST-follow rules:
- NEVER cancel without showing the warning and receiving explicit confirmation
- If user says anything ambiguous (like "算了" / "never mind" in a conversation about something else), do NOT interpret it as cancel intent — ask to clarify
- If the complaint status is already resolved/closed, inform user instead of attempting the API call
1.8 Get Complaint Reasons
Trigger:
- "我可以用什么理由申诉？"
- "What reasons can I use to appeal?"
- "Show available complaint reasons for this order"
- "申诉理由有哪些？"
Behavior:
- Call
get-complaint-reasons with orderNo
- Display the list of available reason codes and descriptions
Output format:
📋 Available Complaint Reasons for Order {orderNo}
│
├─ [{reasonCode}] {reasonDesc}
├─ [{reasonCode}] {reasonDesc}
├─ [{reasonCode}] {reasonDesc}
└─ ...
💡 Note: These are the reasons you can use when initiating an appeal.
This skill does NOT support initiating appeals — only viewing reasons.
Note: This is a read-only informational query. The skill does NOT support actually submitting a new complaint (that requires the user to use the App).
Scene 2: Ad Publish & Management
⚠️ Write Operation Safety Rules
ALL write operations in Scene 2 MUST follow this protocol:
- Pre-check: Verify user has merchant permission (the API itself checks, but inform user clearly on 403/Permission denied)
- Show summary: Before executing any write API, display a complete operation summary
- Explicit confirmation: Wait for user to say "确认" / "confirm" / "发布" / "yes" before proceeding
- Never auto-execute: Even if user says "just do it" in the initial request, still show summary first
2.1 Market Analysis & Reference Pricing
Trigger:
- "我想发一个 USDT/CNY 的卖单广告"
- "帮我挂一个 BTC 买单"
- "当前市场参考价是多少？"
- "What's the reference price for USDT/CNY?"
Behavior:
- Call
getReferencePrice to get market reference prices
- Call
search to analyze current market ad distribution
- Present pricing intelligence to help user decide
Output format (Reference Price):
📊 Market Reference Price
├─ Asset: {asset} / {fiatCurrency}
├─ Reference Price: {currencySymbol}{referencePrice}
├─ Price Scale: {priceScale} decimals
└─ Asset Scale: {assetScale} decimals
Output format (Market Analysis):
📊 Market Ad Analysis: {asset}/{fiat} ({tradeType})
├─ Total Active Ads: {total}
├─ Price Range: {min} ~ {max}
├─ Top 5 Ads:
│ 1. {advNo} | {price} | {surplusAmount} {asset} | Limit: {min}~{max} | {merchantNick}
│ └─ Terms: {remarks or "—"}
│ 2. ...
└─ Recommended Price: {suggestion based on reference + market}
2.2 Ad Configuration
Trigger:
- "用浮动价格，溢价 0.5%"
- "加上支付宝"
- "就按推荐的来"
- "单价改成 6.99，限额改到 1000-100000"
Pre-publish preparation workflow:
Step 1 — Get available categories:
GET /sapi/v1/c2c/agent/ads/getAvailableAdsCategory
→ {"advClassifies": ["mass", "profession", ...]}
Step 2 — Get user's payment methods (for SELL ads, need payId):
GET /sapi/v1/c2c/agent/ads/getPayMethodByUserId
→ [{"payId": 123, "identifier": "ALIPAY", "tradeMethodName": "支付宝"}]
Display rule: Only show tradeMethodName (e.g. "支付宝", "WeChat", "Bank Transfer") to the user.
payId is an internal identifier used only in the API request body — never expose payId values in user-facing output.
Step 3 — Get all system trade methods (for BUY ads, need identifier):
POST /sapi/v1/c2c/agent/ads/listAllTradeMethods
→ [{"identifier": "ALIPAY", "tradeMethodName": "支付宝", ...}]
Ad parameter reference:
| Parameter | Required | Description |
|---|
| classify | Y | Ad category: mass / profession / block / cash (default: mass) |
| tradeType | Y | 0 = BUY, 1 = SELL |
| asset | Y | Crypto: BTC, ETH, USDT, BNB |
| fiatUnit | Y | Fiat: CNY, USD, etc. |
| priceType | Y | 1 = Fixed price, 2 = Floating price |
| price | Conditional | Fixed price value (required if priceType=1) |

This skill does NOT (in Phase 3):
- Initiate new appeals / submit-complaint (only evidence supplement for existing appeals is supported)
- Auto-monitor appeal status changes (polling not supported in skill)
- Place orders on behalf of user (guide to ad detail page instead)
- Access chat messages or send messages in order chat
- Modify payment method configurations (only read)
- Access KYC/verification status details
For appeal initiation and real-time appeal monitoring, guide users to the official P2P dispute center.
