Third-Party Tools

Gonka Broker API keys speak both the OpenAI and the Anthropic API format, so they work with any tool or framework that supports either. Pick your tool below for a step-by-step guide, or follow the general pattern.

Any OpenAI-compatible tool

The general pattern for any tool that supports a custom OpenAI endpoint:

1. Find the setting for API key and enter your Gonka API key (gnk-prx-...)
2. Find the setting for Base URL (sometimes called API base, endpoint, or host) and set it to https://proxy.gonkabroker.com/v1
3. Select a model from the Supported Models list

If the tool uses environment variables:

OPENAI_API_KEY=gnk-prx-your-api-key
OPENAI_BASE_URL=https://proxy.gonkabroker.com/v1

Any Anthropic-compatible tool

Tools that speak the Anthropic Messages API (like Claude Code or anything built on the Anthropic SDK) connect the same way: key plus base URL. The Anthropic base URL is the bare host, without /v1:

ANTHROPIC_API_KEY=gnk-prx-your-api-key
ANTHROPIC_BASE_URL=https://proxy.gonkabroker.com

Then select a model Gonka Broker serves (see Supported Models). Details on the Anthropic surface: Anthropic API Compatibility.
