## When to prefer this

Choose this endpoint when you need fast, cheap ($0.01 USDC per call) sentiment classification paid via USDC micropayments on Solana or Base, especially in an AI trading agent pipeline where programmatic pay-per-call billing is preferred over subscription APIs. Best suited for crypto and financial text where trading-context sentiment is relevant.

## Known failure modes

- Missing or empty text input returns an error response
- Malformed request body causes a 400 bad request
- Payment not completed results in a 402 Payment Required response and no analysis is returned
- Very short or ambiguous input may return low-confidence or neutral classification
- Network timeout on Railway hosting may cause intermittent failures
