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-prod.onrender.com/v1/prepaid/data-quality-gate' \
  -H "Authorization: Bearer $BOUNTY_API_KEY" \
  -H 'Content-Type: application/json' \
  -H 'Idempotency-Key: workflow-request-001' \
  -H 'X-Max-Credits: 2' \
  --data '{"records":[{"id":"a","price":25},{"id":"a","price":25}],"schema":{"type":"object","required":["id","price"],"properties":{"id":{"type":"string"},"price":{"type":"number"}}},"unique_by":["id"]}'

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-prod.onrender.com/v1/prepaid/data-quality-gate. Send JSON and these headers; store the Bearer token as a private credential.

{
  "method": "POST",
  "headers": {
    "Authorization": "Bearer YOUR_PRIVATE_API_KEY",
    "Content-Type": "application/json",
    "Idempotency-Key": "UNIQUE_PER_LOGICAL_REQUEST",
    "X-Max-Credits": "2"
  },
  "body": {
    "records": [
      {
        "id": "a",
        "price": 25
      },
      {
        "id": "a",
        "price": 25
      }
    ],
    "schema": {
      "type": "object",
      "required": [
        "id",
        "price"
      ],
      "properties": {
        "id": {
          "type": "string"
        },
        "price": {
          "type": "number"
        }
      }
    },
    "unique_by": [
      "id"
    ]
  }
}
