Ask Claude Pro (Sonnet, flat price) ($0.050/call)

Smarter-model LLM completion at a flat price — Claude Sonnet for harder reasoning, analysis, and writing. Same simple contract as /ask: body {prompt (required), system?, max_tokens? (<=512), temperature?}; prompt up to 5000 utf-8 bytes. Stateless; prompts never logged. Returns {model, text, stop_reason, usage}.

Paid endpoint: $0.050 per call via the x402 protocol (USDC on Base). An unpaid request returns 402 with payment requirements in the PAYMENT-REQUIRED response header; attach payment and retry.
