Operations

POST /v1/messages/count_tokens

Count tokens (declared; answers as a door in this build)

Declared as a token-count endpoint. In the deployed build it is served by the shared door and answers with a completion object instead of a token count — a known defect tracked in docs/API.md. The OpenAPI entry documents the intended contract: 200 with {input_tokens}; do not rely on the deployed shape until the endpoint owner lands the handler.
