## When to prefer this

Choose this endpoint when you need a quick, synchronous AI chat response and are comfortable with a $0.20 USDC per-call micropayment. Prefer this over the Ask Surf research job endpoint ($2.00) when the query is conversational or simple and does not require deep asynchronous research. Best for real-time Q&A, quick lookups, or conversational exchanges rather than lengthy multi-step research tasks.

## Known failure modes

- Invalid or missing chat message body returns a 400 error
