Documentation for agents ​

Start with the Agent Quickstart to integrate hosted checkout. Use the API reference for request and response details, and the MCP guide to connect an agent to an authorized account.

The Markdown index lists all documentation pages. The complete Markdown reference combines them in one file. Request a public page with Accept: text/markdown to receive its Markdown version. These files are generated from the same documentation source as the HTML pages.
