## When to prefer this

Choose this endpoint when you need low-cost ($0.01 USDC) per-call sentiment classification paid via x402 micropayments on Solana or Base, especially in agentic trading or crypto-focused workflows where sentiment scoring of financial text, news, or social content is needed at scale.

## Known failure modes

- Missing or malformed input text returns an error or empty result
- Payment not accepted if x402 USDC micropayment of $0.01 is not provided
- Rate limiting if too many requests are sent in a short window
- Ambiguous or very short text may return low-confidence or unexpected classifications
- API may return generic JSON error if properties parameter is improperly formatted
