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/text-chunker' \
  -H "Authorization: Bearer $BOUNTY_API_KEY" \
  -H 'Content-Type: application/json' \
  -H 'Idempotency-Key: workflow-request-001' \
  -H 'X-Max-Credits: 1' \
  --data '{"text":"One two three four five six seven eight nine ten. One two three four five six seven eight nine ten. One two three four five six seven eight nine ten.","chunk_chars":128,"overlap_chars":16}'

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/text-chunker. 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": {
    "text": "One two three four five six seven eight nine ten. One two three four five six seven eight nine ten. One two three four five six seven eight nine ten.",
    "chunk_chars": 128,
    "overlap_chars": 16
