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 demurrage costs for a 40HC container in Singapore for 10 days with Maersk.”

Endpoint request body

The JSON payload your agent sends to the endpoint.

application/json

  "days": 10,
  "country": "SG",
  "shipping_line": "MAERSK",
  "container_type": "40HC"
}
