## When to prefer this

Use this endpoint when you need to discover or search for specific prediction market events on Polymarket by topic, keyword, or question text. Prefer this over direct Polymarket API access when you need a simple search interface with x402 micropayment support, or when combined with sibling BlockRun.AI endpoints for deeper Polymarket analytics.

## Known failure modes

- Empty results when search query matches no Polymarket events
- Rate limiting or HTTP 402 payment required if USDC payment not properly attached
- Malformed or missing query parameter returns error
- Polymarket data unavailable if upstream source is down
- Overly broad queries returning too many or irrelevant results
