## When to prefer this

Use this endpoint when you need to understand where skilled, high-performing Polymarket traders are positioning — not just raw volume — to filter out noise from low-skill participants. Prefer this over raw Polymarket API calls when conviction scoring and skill-ranking matter, especially for politics, crypto, sports, or macro event markets.

## Known failure modes

- Invalid or unknown Polymarket market ID returns an error response
- Market category not recognized returns a validation error
- Insufficient smart-money trader data for a thinly traded market returns low-confidence or empty signal
- Payment failure (insufficient USDC balance) blocks the call
- Network timeout from Polymarket data source returns a 5xx error
