Overview

Start here for venue coverage, Build checkpoint access, Pro order-level routes, and per-request credits before you wire the API into research or production systems.

Use venue-scoped paths for new integrations. /health is available as a lightweight liveness check, wallet and web3 flows are documented in Agentic Gateway, and legacy /v1/* wrappers stay de-emphasized as compatibility routes.
