## When to prefer this

Choose this endpoint when you need a fast, per-ticker AI sentiment score for a specific stock and want a pay-per-use model with no subscription overhead. Prefer it over generic news aggregators when you want a pre-computed sentiment signal rather than raw headlines, and over full portfolio analysis endpoints when you only need sentiment (not technicals or risk) for a single symbol.

## Known failure modes

- Invalid or unrecognized ticker symbol returns error or empty data
- Missing required 'symbol' field returns validation error
- Network or upstream AI model latency causing timeout
- Ticker not covered by the sentiment model returns no data
- x402 payment failure or insufficient USDC balance blocks request
