Count Tokens Then Create Message
with Anthropic
Count input tokens for a prompt and conditionally create the message.
- Count the input tokens for the prospective message request without creating the message or charging output tokens.
- Send the prompt as a real message now that the input token total is known to be within budget, and capture the generated response.
What you'll need to have ready
- apiKey: A valid Anthropic API key sent in the x-api-key header.
- model: The Claude model id to count against and generate with.
- prompt: The user prompt text to evaluate and send.
- tokenBudget: The maximum acceptable input token count before sending the message.
- maxTokens: Maximum number of output tokens to generate.
