Skill: crypto-com-app
Agent Capability Requirements
This skill requires your agent platform to support the following capabilities. If your platform lacks any required capability, the skill will not function.
| Capability | Required | Details |
|---|
| Shell command execution | Yes | Must be able to run npx tsx ./scripts/... and capture stdout |
| Environment variables | Yes | Must read CDC_API_KEY and CDC_API_SECRET from the shell environment |
| JSON parsing | Yes | Must parse structured JSON from script stdout to extract fields |
| Multi-turn conversation | Yes | Trading uses a quote → confirm flow that spans multiple user turns |
| Persistent memory | No | Used for confirmation_required preference. If unsupported, default to always confirming trades |
| Elapsed-time awareness | No | Used to check quote expiry (countdown field). If unsupported, always attempt confirmation and handle invalid_quotation errors gracefully |
CRITICAL: How This Skill Works
You MUST use the TypeScript scripts for ALL API interactions. NEVER call the API directly with curl, fetch, or any other HTTP method.
The scripts handle request signing, error handling, and response formatting. If you bypass them:
- The request will fail (missing HMAC signature)
- The response won't be filtered or structured
For every user request, find the matching command below and run it via npx tsx. Read the JSON output. Act on it.
Configurations
- BASE_URL:
https://wapi.crypto.com
- CDC_API_KEY:
{{env.CDC_API_KEY}}
- CDC_API_SECRET:
{{env.CDC_API_SECRET}}
- CONFIRMATION_REQUIRED:
{{memory.confirmation_required}} (Default: true)
- SKILL_DIR: The directory containing this
SKILL.md file. Resolve it from the path you loaded this file from (e.g. if you read /home/user/skills/crypto-com-app/SKILL.md, then SKILL_DIR is /home/user/skills/crypto-com-app).
Environment Setup
-
Both CDC_API_KEY and CDC_API_SECRET must be set as environment variables before use.
-
Before running any script, check whether both variables are set by running:
echo "CDC_API_KEY=${CDC_API_KEY:+set}" "CDC_API_SECRET=${CDC_API_SECRET:+set}"
If either prints empty instead of set, prompt the user:
"Your API credentials are not configured. Please set them in your terminal before I can proceed:
export CDC_API_KEY="your-api-key"
export CDC_API_SECRET="your-api-secret"
You can generate an API key at https://help.crypto.com/en/articles/13843786-api-key-management.
Let me know once you've set them."
Then stop and wait for the user to confirm before retrying.
-
If a script returns a MISSING_ENV error, treat it the same way: prompt the user to set the variables and wait.
Script Commands
ALL API interactions MUST go through these scripts. They handle signing, execution, filtering, and error formatting. Run the appropriate command below via shell, then parse the JSON output.
Prerequisite: npx tsx (Node.js 18+ required; tsx is fetched automatically by npx).
Important: All script paths below use $SKILL_DIR as a placeholder for this skill's root directory. Resolve it from the path you loaded this SKILL.md from, or cd into the skill directory and use ./scripts/... as the path. Either approach works.
Account Commands
npx tsx $SKILL_DIR/scripts/account.ts balances [fiat|crypto|all]
npx tsx $SKILL_DIR/scripts/account.ts balance <SYMBOL>
npx tsx $SKILL_DIR/scripts/account.ts trading-limit
npx tsx $SKILL_DIR/scripts/account.ts resolve-source <purchase|sale|exchange>
npx tsx $SKILL_DIR/scripts/account.ts revoke-key
Trade Commands
Trading follows a two-step flow: get a quotation first, then confirm the order.
npx tsx $SKILL_DIR/scripts/trade.ts quote <type> '<json-params>'
npx tsx $SKILL_DIR/scripts/trade.ts confirm <type> <quotation-id>
npx tsx $SKILL_DIR/scripts/trade.ts history
How to map user intent to trade type:
| User says | Trade type | From | To |
|---|
| "Buy CRO with 100 USD" | purchase | USD (fiat) | CRO (crypto) |
| "Sell 0.1 BTC" | sale | BTC (crypto) | USD (fiat) |
| "Swap 0.1 BTC to ETH" | exchange | BTC (crypto) | ETH (crypto) |
Quotation JSON params by trade type:
| Type | JSON fields |
|---|
| purchase | {"from_currency":"USD","to_currency":"CRO","from_amount":"100"} or use to_amount instead |
| sale | {"from_currency":"BTC","to_currency":"USD","from_amount":"0.1","fixed_side":"from"} |
| exchange | {"from_currency":"BTC","to_currency":"ETH","from_amount":"0.1","side":"buy"} |
Example — "Buy CRO with 100 USD":
- Run:
npx tsx $SKILL_DIR/scripts/trade.ts quote purchase '{"from_currency":"USD","to_currency":"CRO","from_amount":"100"}'
- Read
data.id, data.from_amount, data.to_amount, data.countdown from the response.
- If confirmation required (default): Ask user "Confirm: 100 USD for X CRO? Valid for {countdown}s. Reply 'YES' to proceed."
- If user says YES (within countdown):
npx tsx $SKILL_DIR/scripts/trade.ts confirm purchase <data.id>
- If confirmation opted out (
memory.confirmation_required is false): Skip asking and immediately run npx tsx $SKILL_DIR/scripts/trade.ts confirm purchase <data.id>
Opt-in / Opt-out: Users can say "stop asking for confirmation" to auto-execute trades, or "require confirmation" to re-enable the prompt. See Section 3 below.
Coin Discovery Commands
npx tsx $SKILL_DIR/scripts/coins.ts search '{"keyword":"BTC","sort_by":"rank","sort_direction":"asc","native_currency":"USD","page_size":10}'
Required JSON parameters:
| Parameter | Type | Allowed values |
|---|
sort_by | string | rank, market_cap, alphabetical, volume, performance |
sort_direction | string | asc, desc |
native_currency | string | Uppercase currency code (e.g. USD) |
keyword | string | Search string, 1–100 chars; matches coin name and symbol only |
page_size | integer | Number of results per page |
Optional: page_token — opaque token for fetching the next page (see pagination below).
Pagination: The response includes a pagination object with has_more (boolean) and next_page_token (string). When has_more is true, pass next_page_token as page_token in the next request to fetch the next page.
Key response fields per coin: rails_id (identical to currency_id / currency in trade and account APIs — use this to cross-reference), price_native, price_usd, percent_change_*_native (price performance over past timeframes, e.g. percent_change_24h_native).
Cash (Fiat) Commands
Cash commands handle deposits, withdrawals, and bank account management.
npx tsx $SKILL_DIR/scripts/fiat.ts discover
npx tsx $SKILL_DIR/scripts/fiat.ts payment-networks <CURRENCY>
npx tsx $SKILL_DIR/scripts/fiat.ts deposit-methods <CURRENCY> <DEPOSIT_METHOD>
npx tsx $SKILL_DIR/scripts/fiat.ts email-deposit-info <CURRENCY> <VIBAN_TYPE>
npx tsx $SKILL_DIR/scripts/fiat.ts withdrawal-details <CURRENCY> <VIBAN_TYPE>
npx tsx $SKILL_DIR/scripts/fiat.ts create-withdrawal-order '<json-params>'
npx tsx $SKILL_DIR/scripts/fiat.ts create-withdrawal <ORDER_ID>
npx tsx $SKILL_DIR/scripts/fiat.ts bank-accounts [CURRENCY]
Key parameters:
| Parameter | Description | Example values |
|---|
CURRENCY | Uppercase currency code | USD, EUR, GBP, AUD |
DEPOSIT_METHOD | Network ID from payment-networks | us_ach, sepa, uk_fps |
VIBAN_TYPE | Same as deposit method / withdrawal network | us_ach, sepa, uk_fps |
Withdrawal order JSON params:
| Field | Required | Description |
|---|
currency | Yes | Currency code (e.g. "USD") |
amount | Yes | Amount as string (e.g. "500.00") |
viban_type | Yes | Payment network (e.g. "us_ach") |
bank_account_id | No | Specific bank account ID |
Example — "How do I deposit USD?":
- Run:
npx tsx $SKILL_DIR/scripts/fiat.ts payment-networks USD
- Read
data array — each entry has deposit_push_payment_networks (e.g. ["us_ach", "us_wire_transfer"])
- For details:
npx tsx $SKILL_DIR/scripts/fiat.ts deposit-methods USD us_ach
- Read
data array — contains bank_details with routing number, account number, etc.
Example — "Withdraw 500 USD via ACH":
- Run:
npx tsx $SKILL_DIR/scripts/fiat.ts withdrawal-details USD us_ach — check quotas and fees
- Run:
npx tsx $SKILL_DIR/scripts/fiat.ts create-withdrawal-order '{"currency":"USD","amount":"500","viban_type":"us_ach"}'
- Read
data.id (order ID), data.fee, data.receivable_amount from response
- Confirm with user: "Withdraw 500 USD via ACH. Fee: {fee}. You'll receive: {receivable_amount}. Confirm?"
- If YES:
npx tsx $SKILL_DIR/scripts/fiat.ts create-withdrawal <order-id>
- If TOTP required, the script will prompt for a 6-digit authenticator code on stderr
Output Format
Every script prints structured JSON to stdout:
Success:
{"ok": true, "data": { ... }}
Error:
{"ok": false, "error": "ERROR_CODE", "error_message": "Human-readable message"}
Constraints
- Validation: Success requires
ok: true in the script output.
- Confirmation Window: Quote validity is defined by the
countdown field in the quotation data.
- Execution Warning: If order confirmation takes > 5s, notify: "Order submitted but taking longer than expected. Check order status with 'Show recent trades'".
- Rate Limits:
- Max 10 trades per minute.
- Max 100 API calls per minute.
- On HTTP 429 (
RATE_LIMITED error): wait 60 seconds before retrying the same request. Inform the user: "Rate limit reached — please wait 60 seconds before trying again."
Error Handling
All scripts return structured errors. Parse the error field to determine the appropriate response.
Script Error Codes
These are the error values in the script's JSON output. They tell you what category of failure occurred.
| Error Code | Meaning | Agent Response |
|---|
MISSING_ENV | CDC_API_KEY or CDC_API_SECRET not set | Tell user to set env vars via terminal |
API_ERROR | API returned non-200 or ok !== true | Report: "Transaction failed: {error_message}" |
INVALID_ARGS | Bad command-line arguments | Show correct usage from the error_message |
QUOTATION_FAILED | Quotation request rejected by API | Report the error_message to user (see API errors below) |
EXECUTION_FAILED | Order confirmation failed | Report and suggest: "Check order status with 'Show recent trades'" |
API_KEY_NOT_FOUND | Key already revoked or does not exist | "API key not found — it may have already been revoked." |
RATE_LIMITED | Too many requests (HTTP 429) | "Rate limit reached — please wait 60 seconds before trying again." |
UNKNOWN | Unexpected error | Report the raw error_message |
Rule: When ok is false in the output, stop the current operation and report the error to the user using the guidance above. Never proceed to the next step after a failure.
Common API Errors (Quick Reference)
These are the specific API error codes that appear inside the error_message of QUOTATION_FAILED, EXECUTION_FAILED, or API_ERROR responses. They tell you why the API rejected the request.
error | Meaning | Recovery |
|---|
not_enough_balance | Insufficient funds | Check balances, reduce trade amount |
invalid_currency | Currency code not recognized | Verify via coin search |
invalid_quotation | Quote expired or already used | Request a new quotation |
failed_to_create_quotation | Quotation engine error | Retry shortly |
not_eligible_for_prime | Not eligible for Prime benefits | Proceed without Prime |
unauthorized | Account not approved for trading | Contact support |
restricted_feature | Feature restricted on account | Report error_message to user |
existing_currency_order_error | An existing order is in progress | Wait or cancel existing order |
viban_purchase_not_enabled | Fiat-to-crypto not enabled | Account feature not available |
crypto_viban_not_enabled | Crypto-to-fiat not enabled | Account feature not available |
bank_transfer_not_enabled | Bank transfer not enabled | Account feature not available |
missing_parameter | Required parameter missing | Script bug — report it |
failed_to_create_transaction | Transaction creation failed | Retry or contact support |
key_not_active | API key revoked or expired | Generate a new API key, update env vars |
api_key_not_found | Key doesn't exist or belongs to another user | Verify correct key is set in CDC_API_KEY |
totp_required | Withdrawal needs 2FA code | Script handles automatically — prompts user for authenticator code |
withdrawal_limit_exceeded | Daily/monthly quota exceeded | Show limits via withdrawal-details, reduce amount |
invalid_bank_account | Bank account not eligible | Check bank-accounts for valid accounts with status: completed |
withdrawal_cooling_off | Recently changed withdrawal settings | Wait for cooling-off period, report error_message to user |
email_cooldown | Too many deposit info emails | Wait for cooldown period (shown in error), try again later |
For dynamic errors (limit exceeded, currency disabled, cooling-off, etc.), report the error and error_message directly to the user. For full details, see references/errors.md.
Logic & Rules
1. Asset & Source Disambiguation
Determine the trade type first:
- Purchase — fiat → crypto
- Sale — crypto → fiat
- Exchange — crypto → crypto
Then resolve the source wallet:
- For purchase: run
npx tsx $SKILL_DIR/scripts/account.ts resolve-source purchase. The script returns only funded fiat entries.
- For sale or exchange: run
npx tsx $SKILL_DIR/scripts/account.ts resolve-source sale (or exchange). The script returns only funded crypto entries.
Result (from data.status):
SELECTED → auto-select data.currency.AMBIGUOUS → prompt user to choose from data.options.EMPTY → inform user "No funded wallets found" and stop.
"Sell All" Scenario: If user says "Sell all [TOKEN]", run npx tsx $SKILL_DIR/scripts/account.ts balance [TOKEN]. Use the data.available amount (or data.balance) as from_amount for the quotation.
2. Trading Process (Quotation → Confirmation → Execution)
When the user asks to buy, sell, or swap crypto, always follow this three-step flow:
-
Step A — Get Quotation: Build the JSON params from the user's request (see the "Quotation JSON params" table in Trade Commands) and run:
npx tsx $SKILL_DIR/scripts/trade.ts quote <type> '<json-params>'
Read data.id, data.from_amount, data.to_amount, and data.countdown from the response.
-
Step B — Ask User to Confirm:
- IF
memory.confirmation_required is true (or unset):
- Prompt: "Confirm: {from_amount} for {to_amount}? Valid for {countdown}s. Reply 'YES' to proceed."
- Expiration Logic: If the user replies "YES" after
countdown seconds have elapsed, reject: "Transaction rejected: The quotation rate has expired. Please request a new quote."
- Execute Step C ONLY if user replies "YES" within the valid window.
- ELSE (Opted Out):
- Notify: "Quotation received. Proceeding to execution automatically..."
- Immediately proceed to Step C.
-
Step C — Execute Order: Run: npx tsx $SKILL_DIR/scripts/trade.ts confirm <type> <data.id> using the id from Step A.
3. Memory Management (Opt-in/Out)
- To Opt-out: If user says "stop asking for confirmation" or "enable auto-trade", update
memory.confirmation_required to false.
- To Opt-in: If user says "require confirmation" or "enable manual trade", update
memory.confirmation_required to true.
- Platforms without persistent memory: If your platform does not support
{{memory.*}}, treat confirmation_required as always true (safest default).
4. Error Handling
- All script outputs include an
ok field. Success is defined ONLY as ok: true.
- If
ok is false, read error and respond per the Error Handling table above.
- Never proceed to the next step after a failed command.
5. Account & History
- History: Run
npx tsx $SKILL_DIR/scripts/trade.ts history — display the entries from data.
- Weekly Trading Limit: Run
npx tsx $SKILL_DIR/scripts/account.ts trading-limit — display as: "📊 Weekly Trading Limit: {data.used} / {data.limit} USD (Remaining: {data.remaining} USD)".
- Fiat vs Crypto balance routing: When the user asks about a specific currency balance, determine whether it is a fiat currency (USD, EUR, GBP, AUD, SGD, CAD, BRL, etc.) or a crypto token (BTC, ETH, CRO, etc.).
- Fiat currency → run
npx tsx $SKILL_DIR/scripts/account.ts balances fiat (shows all fiat balances) or npx tsx $SKILL_DIR/scripts/fiat.ts discover (shows balances + payment networks). Never use balance <SYMBOL> for fiat currencies — it queries the crypto wallet and will always return 0.
- Crypto token → run
npx tsx $SKILL_DIR/scripts/account.ts balance <SYMBOL>.
- Unsure → run
npx tsx $SKILL_DIR/scripts/account.ts balances all to show both fiat and crypto.
- Balances (Categorized):
- If "List Fiat": run
npx tsx $SKILL_DIR/scripts/account.ts balances fiat.
- If "List Crypto": run
npx tsx $SKILL_DIR/scripts/account.ts balances crypto.
- If "List All": run
npx tsx $SKILL_DIR/scripts/account.ts balances all. Crucial: Display Fiat category first, followed by Crypto balances below.
- The scripts automatically filter out zero-balance entries. If a category has no entries in the output, display "No holdings" under that header.
- Crypto balances (
data.crypto) contain a note field ("available for trading") and a wallets array. Always clarify to the user that these amounts are what's available for trading — total holdings across all products may be higher.
- Portfolio Allocation: When crypto balances are queried, the output may include a
portfolio_allocation array — each entry has a product name and price_native (USD value). Display this as a summary of the user's asset distribution across products (e.g. Crypto Wallet, Exchange, Earn, Staking, etc.).
- Single token balance (
balance <SYMBOL>) output may include a product_allocation object — keys are product names (e.g. crypto_earn, staking, supercharger, crypto_basket, airdrop_arena) and values are the token amounts held in each. Only non-zero products are included. Summarize these allocations to the user alongside the available-for-trading amount so they see the full picture of where their tokens are held.
6. Kill Switch
- Trigger: User says "STOP ALL TRADING", "kill switch", or similar emergency stop command.
- ALWAYS require explicit confirmation regardless of
memory.confirmation_required:
- Prompt: "⚠️ WARNING: This will immediately revoke your API key and disable all trading. A new API key must be generated to resume. Type 'CONFIRM KILL SWITCH' to proceed."
- Execute ONLY if user replies with the exact phrase.
- Execution: Run
npx tsx $SKILL_DIR/scripts/account.ts revoke-key.
- On success (
ok: true): Notify: "🛑 Kill switch activated. API key has been revoked. All trading is disabled. Generate a new API key and update your environment variables to resume."
- On
API_KEY_NOT_FOUND error: Notify: "API key not found — it may have already been revoked or does not exist."
- Idempotency: Revoking an already-revoked key is not an error; treat it the same as a successful revocation.
7. Balance Display Format
- Fiat Header: "🏦 Fiat Balances"
- Crypto Header: "🪙 Crypto Balances"
- Always list Fiat section before Crypto section when both are requested.
- Never display zero-balance assets. Only show assets with a balance greater than 0. If all assets in a category are zero, show "No holdings" under that header.
8. Cash Deposit & Withdrawal
Terminology: Use "cash" (not "fiat") in user-facing messages. Say "your cash balance" not "your fiat balance".
Currency disambiguation: If the user doesn't specify a currency, run discover first.
- One currency with balance → auto-select it and proceed.
- Multiple currencies with balances → present the list and ask the user to choose before proceeding.
- No balances → inform: "You don't have any cash balances yet." and stop.
Deposit flow:
- Run
discover to show the user their cash currencies and available networks
- User picks a currency and network — run
deposit-methods to get bank details
- Present the bank details (routing number, account number, bank name, reference)
- Optionally run
email-deposit-info to email instructions to the user
- Rate limit:
email-deposit-info is limited to 5 requests per 30 minutes. On cooldown error, inform user and show the cooldown_in_seconds value.
Withdrawal flow:
- Run
bank-accounts <currency> to list eligible accounts (filter to status: "completed" only)
- One eligible account → auto-select it
- Multiple eligible accounts → present the list (bank name, account identifier, networks) and ask user to choose
- No eligible accounts → inform: "No eligible bank accounts found for {currency}. You need to link a bank account first." and stop
- Run
withdrawal-details to check quotas, fees, and minimums
- Run
create-withdrawal-order with amount, network, and bank_account_id from step 1 — returns order with fees
- ALWAYS confirm with user before executing (regardless of
memory.confirmation_required):
- Show: amount, fee, receivable amount, network, destination bank account, processing time
- Require explicit "YES" to proceed
- Run
create-withdrawal with the order ID
- TOTP handling: If the API returns
totp_required, the script prompts for a 6-digit authenticator code on stderr. The agent should tell the user: "Please enter your 6-digit authenticator code when prompted." Never try to generate or bypass the TOTP.
Bank accounts:
- Run
bank-accounts to list linked accounts. Filter by currency if specified.
- Only accounts with
status: "completed" are eligible for withdrawals.
- Each account shows
withdrawal_payment_networks — use these as valid viban_type values.
Deposit methods — vendor selection:
deposit-methods returns a vendor_list array. Each vendor has a status field.- Only show vendors with
status: "created" (active). Ignore "uncreated" vendors.
- If multiple created vendors exist, default to the first one in the list.
Cash commands quick reference:
| User says | Commands to run |
|---|
| "How do I deposit USD?" | payment-networks USD then deposit-methods USD <network> |
| "Email me deposit instructions" | email-deposit-info <currency> <viban_type> |
| "Show my bank accounts" | bank-accounts |
| "What are my withdrawal limits?" | withdrawal-details <currency> <viban_type> |
| "Withdraw 500 USD" | withdrawal-details -> create-withdrawal-order -> confirm -> create-withdrawal |
| "What currencies can I deposit?" | discover |
