# SDK Reference

> Use existing OpenAI and Anthropic SDKs against the gateway, or download a typed Agent Router client for Go, Python, or TypeScript.

# SDK Reference

  Because the gateway is OpenAI-compatible and Anthropic-compatible, the existing provider SDKs work unchanged: point the SDK's base URL at the gateway and pass an Agent Router API key. No Agent Router-specific SDK is required. For teams that prefer a first-class client, typed Agent Router SDKs are also published for Go, Python, and TypeScript.

## Use an existing provider SDK

The lowest-friction path is to keep the SDK an application already uses. The OpenAI and Anthropic client libraries call the same API shapes the gateway serves, so only two things change: the base URL is set to the gateway endpoint, and the API key is an Agent Router key rather than a provider key. Existing request and response handling is untouched. This approach is covered end to end, with per-language snippets, in [Integrate the gateway with an app](/agent-router-service/guides/integrate-the-gateway-with-an-app).

## Typed Agent Router SDKs

A typed client for Go, Python, or TypeScript can be downloaded when a generated, strongly typed surface over the management API is preferred. Each artifact is the Agent Router SDK source tree at the release shown above, distributed from `https://tare.tetrate.ai/tools/sdks/stable/`.

## Quickstarts

Each quickstart installs the client for one language, then makes a first read-only identity call to confirm the key and base URL are wired correctly. The curl quickstart needs no SDK at all.

## API specifications

Machine-readable descriptions of the management API are available as a combined OpenAPI 3.1 document and a Postman v2.1 collection. The OpenAPI document supports client generation and contract tooling; the Postman collection supports interactive exploration and testing.
