Anthropic Messages

Anthropic Messages API surface.

01概述

Accepts Anthropic Messages requests and translates them through CAPI's shared chat relay. Existing clients can use the Anthropic request shape; tool use, image input, streaming, and other model-specific features depend on the configured upstream. Anthropic-only features are not guaranteed to map to every OpenAI-compatible channel.
