WeaveAPI Anthropic-compatible Messages API is one of 2 APIs that [WeaveAPI - OpenAI-compatible AI API Gateway](https://apis.io/providers/weaveapi/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Artificial Intelligence, LLM, AI Inference, Anthropic Compatible, and Agent Tools. The published artifact set on APIs.io includes API documentation and authentication docs.

Anthropic/Claude-wire-compatible messages route served from the bare api.weaveapi.dev host. The Claude Code setup guide instructs clients to use the host WITHOUT /v1 because Claude-compatible clients build the messages path themselves; the route resolves at POST /v1/messages and is confirmed live and auth-gated. Uses the same WeaveAPI bearer key. No model in the public catalog declares Anthropic endpoint support, so which routes answer here is not publicly verifiable.
