Use with AXON

Run this through your governed agent wallet.

  1. 01
    Bootstrap AXON once with npx @axon402/init.
  2. 02
    Use the AXON runtime MCP tools to search_x402_services or inspect_x402_offer for this service.
  3. 03
    Quote, test-buy, then run the governed paid fetch through AXON.

Send this

Prompt for your agent

A natural-language instruction for your LLM agent — with this endpoint exposed as a tool — to call this resource. Not sent to the endpoint; the endpoint consumes the JSON body below.

Pasting this prompt into a raw ChatGPT or unconfigured agent will notexecute the paid endpoint flow. Run it through an agent with the AXON runtime / MCP tools exposed (see “Use with AXON” above) so the 402 challenge, quote, and governed fetch are handled for you.

“Test my webhook at https://example.com/webhook with a POST request and custom headers”

Endpoint request body

The JSON payload your agent sends to the endpoint.

application/json
{
  "url": "https://example.com/webhook",
  "body": {
    "test": "data"
  },
  "method": "POST",
  "headers": {
    "Authorization": "Bearer token"
  },
  "timeout": 10
}

Advanced HTTP details

For integrators who need the raw protocol surface. Most agents should use AXON above instead of calling these directly.

curl fallback

curl https://webhook-tester-production-e956.up.railway.app/api/test \
  -H "Content-Type: application/json" \
  -H "X-PAYMENT: [signed_payment_envelope]" \
  -d '{"url":"https://example.com/webhook","body":{"test":"data"},"method":"POST","headers":{"Authorization":"Bearer token"},"timeout":10}'

Payment & settlement details

Raw on-chain settlement parameters. AXON above handles these automatically through quote / test-buy / governed fetch.
