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.

“Calculate the mortgage payment for a $500,000 loan at 6.5% for 30 years”

Endpoint request body

The JSON payload your agent sends to the endpoint.

{
  "years": 30,
  "principal": 500000,
  "annual_rate": 6.5
}

Advanced HTTP details

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

Payment & settlement details
