Anthropic

Anthropic's first-party API — direct route to Claude, US-hosted.

The reference route to the Claude family. Anthropic hosts its own models on US infrastructure with the full upstream feature surface — new model releases, beta features, and tool-use flags land here first. Pick this route when you need guaranteed parity with the latest Claude releases and aren't constrained by EU residency.
