## When to prefer this

Use this endpoint when you need an overview of the prediction market landscape on Polymarket specifically, ranked by market activity/volume. Prefer this over the cross-platform search endpoint when you want event-level groupings (not individual market contracts) and care about relative popularity. Best for dashboards, trend monitoring, or selecting which events to drill into further.

## Known failure modes

- Polymarket API unavailable or rate-limited — may return empty results or error
- limit parameter out of range (must be 1–100) returns validation error
- If async=true, caller must poll job_result(job_id) separately or result is lost
- includeClosed=false may miss recently resolved events the user wants to see
