Connect in curl

Set BOUNTY_API_KEY privately after your payment is verified. Change the retry key for each new logical request.

curl 'https://bounty-engineer-x402-api.onrender.com/v1/prepaid/settlement-ledger-audit' \
  -H "Authorization: Bearer $BOUNTY_API_KEY" \
  -H 'Content-Type: application/json' \
  -H 'Idempotency-Key: workflow-request-001' \
  -H 'X-Max-Credits: 49' \
  --data '{"entries":[{"id":"e1","settlement_id":"s1","status":"settled","amount_usd":25,"receipt_hash":"0xabc"},{"id":"e2","settlement_id":"s2","status":"pending","amount_usd":10}]}'

Connect in n8n

Download the inactive n8n template. Import it, configure the private Header Auth credential, inspect the sample and run it manually. A new execution creates a new billable request; there is no automatic schedule.

Use an HTTP POST to https://bounty-engineer-x402-api.onrender.com/v1/prepaid/settlement-ledger-audit. Send JSON and these headers; store the Bearer token as a private credential.

  "method": "POST",

    "Content-Type": "application/json",
    "Idempotency-Key": "UNIQUE_PER_LOGICAL_REQUEST",
    "X-Max-Credits": "49"
