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.

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.

“Validate this customer dataset: emails must be valid format, ages must be 18-100, and country must be in approved list.”

Endpoint request body

The JSON payload your agent sends to the endpoint.

application/json
{
  "data": [
    {
      "age": 25,
      "email": "user@example.com",
      "country": "US"
    }
  ],
  "rules": "Emails must be valid format, ages must be between 18 and 100, country must be in approved list"
}

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://gg402.vercel.app/data_validation_custom \
  -H "Content-Type: application/json" \
  -H "X-PAYMENT: [signed_payment_envelope]" \
  -d '{"data":[{"age":25,"email":"user@example.com","country":"US"}],"rules":"Emails must be valid format, ages must be between 18 and 100, country must be in approved list"}'

Payment & settlement details

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