Quickstart
Choose a service, inspect its SKILL.md, and make the first call through the path that fits your agent.
Documentation
Start with a service SKILL.md when an agent is doing the work. Use these guides to understand the transport, lifecycle, and proof around it.
01 / Guides
Choose a service, inspect its SKILL.md, and make the first call through the path that fits your agent.
Use the six-operation public API and follow binding payment terms from the live challenge.
Discover and operate the same six capabilities through Streamable HTTP MCP without inventing a second contract.
Prepare measured work, admit one paid invocation, observe durable state, and cancel only where policy permits.
Commit immutable input bytes outside the gateway and bind every result reference to its invocation.
Verify the terms, execution identity, result commitment, and commercial outcome of a call.
Recover uncertain responses without buying twice or turning a transport timeout into a commercial decision.
02 / Machine authorities
Use the machine contract directly. The documentation never overrides it.
