Choose this endpoint when you need lightweight, pay-per-call sentiment classification without a subscription commitment, especially in agent pipelines that process text on demand. It is well-suited for single-text sentiment scoring integrated into larger automation workflows via x402 micropayments on Base (USDC).

## Known failure modes

- Very short or ambiguous text may produce low-confidence or unreliable classifications
- Non-English text may not be supported or may return incorrect results

- Malformed input schema returns a 400-level error
