Spraay Payments 💧

Batch crypto payments and payroll via the Spraay x402 gateway.

All requests in this skill go exclusively to the user's configured SPRAAY_GATEWAY_URL. No data is sent to any other external endpoint.

Important Warnings

Blockchain transactions are irreversible. Once a batch payment or transfer is executed on-chain, it cannot be undone. Always confirm the following with the user before executing any payment:

• Recipient addresses are correct
• Token type and chain are intended
• Amounts are accurate
• The user understands x402 micropayment fees will be charged per API call

Real funds are involved. Every paid endpoint costs a small USDC micropayment via the x402 protocol. Batch payments move real tokens on real blockchains. Do not execute payments without explicit user confirmation.

Setup

The gateway URL must be set in your environment or openclaw.json:

SPRAAY_GATEWAY_URL=https://gateway.spraay.app

No API key is needed. Payments are made per-request via the x402 HTTP payment protocol (HTTP 402 → pay → retry). An x402-compatible wallet (Coinbase CDP or similar) handles this automatically.

Supported Chains

Base, Ethereum, Arbitrum, Polygon, BNB Chain, Avalanche, Unichain, Plasma, BOB.

Payment contract (Base): 0x1646452F98E36A3c9Cfc3eDD8868221E207B5eEC

Workflows

Batch Payments

Send tokens to multiple wallets in one transaction. Saves 60-80% on gas compared to individual transfers.

Always confirm recipients, amounts, token, and chain with the user before executing.

curl -X POST "$SPRAAY_GATEWAY_URL/api/batch-payment" \
  -H "Content-Type: application/json" \
  -d '{
    "recipients": [
      {"address": "0xABC...123", "amount": "10"},
      {"address": "0xDEF...456", "amount": "25"}
    ],
    "token": "USDC",
    "chain": "base"
  }'

If you receive HTTP 402, the response body contains payment instructions. Pay the facilitator, then retry with the X-PAYMENT header containing the proof.

Payroll

Payroll uses the same batch payment endpoint. ENS and Basename addresses resolve automatically.

Always confirm the payroll roster with the user before sending.

curl -X POST "$SPRAAY_GATEWAY_URL/api/batch-payment" \
  -H "Content-Type: application/json" \
  -d '{
    "recipients": [
      {"address": "alice.eth", "amount": "3000"},
      {"address": "bob.base", "amount": "2500"}
    ],
    "token": "USDC",
    "chain": "base",
    "memo": "March 2026 payroll"
  }'

Check Token Balance

curl "$SPRAAY_GATEWAY_URL/api/balance?address=0xABC...&chain=base"

Create Invoice

curl -X POST "$SPRAAY_GATEWAY_URL/api/create-invoice" \
  -H "Content-Type: application/json" \
  -d '{
    "recipient": "0xABC...123",
    "amount": "500",
    "token": "USDC",
    "chain": "base",
    "memo": "March consulting"
  }'

Resolve ENS / Basename (Free — No Payment Required)

curl "$SPRAAY_GATEWAY_URL/api/resolve?name=vitalik.eth"

Token Price (Free — No Payment Required)

curl "$SPRAAY_GATEWAY_URL/api/price?symbol=ETH"

Use this to show users the USD value of their payment before executing.

Free Endpoints

These require no x402 payment:

• GET /api/price?symbol=ETH — Token prices
• GET /api/resolve?name=vitalik.eth — ENS/Basename resolution
• GET /api/health — Gateway health check
• GET /api/chains — List supported chains

x402 Payment Flow

1. Call any paid endpoint.
2. Receive HTTP 402 with payment details.
3. Agent wallet sends micropayment to the facilitator.
4. Retry the request with the X-PAYMENT proof header.
5. Receive the response.

Typical cost: fractions of a cent in USDC on Base.

Error Handling

• 402 — Payment required. Follow instructions in response body.
• 400 — Bad request. Check parameters.
• 404 — Endpoint not found.
• 500 — Server error. Retry after a moment.

Tips

• Always confirm with the user before sending any payment.
• Use /api/price to show USD values before executing.
• Resolve ENS/Basenames first to validate addresses.
• Chain defaults to base if not specified.
• Token defaults to USDC if not specified.
