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/schema-drift-guard' \
  -H "Authorization: Bearer $BOUNTY_API_KEY" \
  -H 'Content-Type: application/json' \
  -H 'Idempotency-Key: workflow-request-001' \
  -H 'X-Max-Credits: 3' \
  --data '{"before":{"type":"object"},"after":{"type":"object"}}'

Connect in n8n

Optional daily template (eligible low-cost tools only). Each scheduled execution uses paid credits, even on unchanged data. Customer approval, funds and activation are required.

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/schema-drift-guard. 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": "3"
  },
  "body": {
    "before": {
      "type": "object"
    },
    "after": {
      "type": "object"
    }
  }
}

Reuse a retry key only for the same input. Failed execution returns reserved credits. Full integration and recovery guide · Machine-readable recipe
