3> The API contract between Claude Code and an LLM gateway: endpoints, headers and body fields to forward, feature degradation when fields are stripped, attribution headers for cost tracking, and model discovery.
3> Keep an LLM gateway compatible with Claude Code: the endpoints it calls, the headers and body fields to forward, and what breaks when they're stripped.

55This page documents the requests Claude Code sends to a gateway, including the endpoints it calls, the headers and body fields the gateway must forward, and which features stop working when it doesn't. It is written for operators configuring a gateway product to work with Claude Code.

7A running [Claude apps gateway](/docs/en/claude-apps-gateway) serves a machine-readable version of this contract at `GET /protocol`, covering the same forwarding requirements plus the Claude apps gateway-specific endpoints for SSO sign-in, managed-settings delivery, and telemetry. Claude apps gateway runs from the same `claude` binary as the CLI, so the [Claude apps gateway quickstart](/docs/en/claude-apps-gateway#quickstart) is the shortest path to a running instance you can fetch the spec from.
7The [Claude apps gateway](/docs/en/claude-apps-gateway), Anthropic's self-hosted gateway, serves its own endpoint reference at `GET /protocol`, covering that gateway's sign-in, inference, managed settings, model discovery, and telemetry endpoints. It is a separate document from this guide.
