Every guide has the same three steps: create a key, add Deference to the tool, then check the request in Activity. For Aider, Roo Code and any tool that takes a custom OpenAI or Anthropic base URL, see [Other tools](https://deference.si/docs/coding-tools/other-tools).

To let your agent create and revoke its own keys, connect the [MCP server](https://deference.si/docs/coding-tools/mcp).

## Base URLs

* OpenAI format (Most SDKs and tools): `https://deference.si/v1`
* Anthropic format (Claude Code and the Anthropic SDK): `https://deference.si`

Anthropic clients add `/v1/messages` themselves, so their base URL has no `/v1`. A doubled or missing `/v1` returns 404.

3 requests from a coding tool, across 2 sessions, add $0.50 of free credit. [How free credit works](https://deference.si/docs/concepts/free-credit)
