Documentation

The shortest path to a correct call.

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

Follow the job, not the plumbing.

01

Quickstart

Choose a service, inspect its SKILL.md, and make the first call through the path that fits your agent.

02

HTTP + x402

Use the six-operation public API and follow binding payment terms from the live challenge.

03

MCP

Discover and operate the same six capabilities through Streamable HTTP MCP without inventing a second contract.

04

Invocation lifecycle

Prepare measured work, admit one paid invocation, observe durable state, and cancel only where policy permits.

05

Artifacts

Commit immutable input bytes outside the gateway and bind every result reference to its invocation.

06

Receipts

Verify the terms, execution identity, result commitment, and commercial outcome of a call.

07

Retries and errors

Recover uncertain responses without buying twice or turning a transport timeout into a commercial decision.

02 / Machine authorities

Need the exact bytes?

Use the machine contract directly. The documentation never overrides it.
