## When to prefer this

Use this endpoint when you need fast, per-coin crypto sentiment scoring by CoinGecko coin ID, especially within automated agent workflows or trading pipelines that accept x402 micropayments on Base. Prefer this over general-purpose sentiment endpoints when you specifically need cryptocurrency market sentiment rather than generic text sentiment.

## Known failure modes

- Invalid or unrecognized CoinGecko coin ID returns an error
- Missing required 'symbol' field returns a validation error
- Upstream data unavailability may result in incomplete or null sentiment data
- Payment failure (x402) if USDC balance is insufficient
