Provider
Anthropic through one endpoint
3 Anthropic models, billed at Anthropic's own list price with nothing added - alongside every other provider on the same key, with routing and fallback between them.
Where your requests go, and what happens to them
We call api.anthropic.com, served from the United States. Their models are also sold through EU regions of Bedrock and Vertex, which we do not integrate.
Read on Anthropic's own terms, last checked 2026-08-21 - their published policy. Recorded as a published position rather than a commitment we can make on their behalf, which is why the date is here.

You do not have to choose Anthropic for everything
That is the point of a gateway: route the cheap work elsewhere, keep Anthropic for what it is best at, and fall through to another provider when this one has a bad day - on one key, with one bill and one log.
