Anthropic
Connect Anthropic as an AI Gateway provider
An Anthropic provider forwards Messages requests to Anthropic's API. Attach it to an AI Gateway resource when you want Claude Code, Claude Desktop, OpenCode, OpenClaw, or any other Anthropic-compatible client to use your org's Anthropic key.
See AI Providers if you haven't created a provider before. Field options are in Provider Configuration.

*allows every model key;claude-*is a typical narrower pattern. - Save, then attach the provider to an AI Gateway resource.
Leave the upstream URL as the default unless you are pointing at a compatible Anthropic-style base URL.
Clients can send anthropic-version themselves. You can also set it as a custom header on the provider (anthropic-version: 2023-06-01). A header set on the provider is always sent upstream and overrides the same header from the client.
