Anthropic Claude API pricing Claude Token Counting API

The official Token Counting API accepts the same message shape as Claude Messages and returns input token estimates before sending a request. This page does not call that API or collect API keys.

Web search, code execution, and managed-agent session fees are excluded from this first version so the core token and prompt-cache flow stays easy to use.
