API Reference

Complete parameter documentation

Parameter Type Default Description
stream boolean true Enable streaming responses for real-time output.
temperature number 0.2 Controls randomness. Higher values can increase creativity.
max_tokens number 8192 Maximum number of tokens to generate in the response.
top_p number 0 Nucleus sampling: considers tokens with top_p probability mass.
reasoning_effort select medium Controls how much reasoning depth Claude applies (quality vs latency).
