Example prompt: Can you score today's top crypto news headlines for sentiment — I want to know how many are bullish vs bearish vs neutral, and which ones are driving the overall tone?

## When to prefer this

Choose this endpoint when you need a fast, lightweight, keyword-based sentiment signal across a batch of crypto headlines without requiring a large language model inference step. It is well-suited for high-frequency polling, quick market mood checks, or pre-filtering headlines before deeper analysis. Prefer alternatives if you need nuanced semantic understanding, entity-level sentiment, or support for non-crypto financial instruments.

## Known failure modes

- Empty or missing headlines array returns zero counts with no per-headline data
- Ambiguous headlines with no matching keywords are classified as neutral
- Non-English headlines may be misclassified due to keyword dictionary limitations
- HTTP 402 returned if USDC payment is not included or insufficient
- Overly long headlines may be truncated or produce unexpected keyword matches
