## When to prefer this

Use this endpoint when you need to identify genuinely skilled Polymarket traders (not just high-bankroll participants), want to discover smart money beyond raw profit rankings, need category-specific trader intelligence, or want to expose high-volume losing traders that standard leaderboards obscure. Prefer this over generic Polymarket data endpoints when the goal is trader quality assessment and skill-based ranking rather than raw trade data or market odds.

## Known failure modes

- Invalid period enum value returns error
- Invalid category enum value returns error
- Limit outside 1-25 range returns validation error
- Insufficient trading data for short time windows may return sparse results
- Polymarket data source unavailability may cause stale or empty responses

## How this service works

Polymarket leaderboard re-ranked by skill, not size: top traders by edge over the odds paid, return and consistency, for day, week, month or all time, optionally per category (sports, politics, crypto, economy). Exposes big-volume losers the profit leaderboard hides.

## Output

A ranked list of up to 25 Polymarket traders scored by skill metrics including edge over the market odds, return performance, and consistency — surfacing genuinely skilled traders and exposing high-volume losers that standard profit-based leaderboards conceal. Results can be scoped to a specific time period (day, week, month, all-time) and market category (sports, politics, crypto, economy, other).
