  2. 02
    Use the AXON runtime MCP tools to search_x402_services or inspect_x402_offer for this service.

    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.

“Check if 'racecar' is a palindrome.”

Endpoint request body

The JSON payload your agent sends to the endpoint.

application/json
{
  "text": "racecar"
}

Advanced HTTP details

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