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/context-pack' \
  -H "Authorization: Bearer $BOUNTY_API_KEY" \
  -H 'Content-Type: application/json' \
  -H 'Idempotency-Key: workflow-request-001' \
  -H 'X-Max-Credits: 1' \
  --data '{"query":"Pro plan price","sources":[{"id":"s1","url":"https://example.com","text":"The Pro plan costs $25 per month."}],"max_chars":1000}'

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/context-pack. 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": "1"
  },
  "body": {
    "query": "Pro plan price",
    "sources": [
      {
        "id": "s1",
        "url": "https://example.com",
        "text": "The Pro plan costs $25 per month."
