## When to prefer this

Use this endpoint when an AI trading or research agent needs real-time crowd-sourced probability estimates from Polymarket for any event, without needing a Polymarket API key or account. Ideal for agents that need keyless, pay-per-call access to prediction market data for decision-making, event probability lookups, or sentiment analysis via market odds.

## Known failure modes

- No markets found for the given keyword — returns empty results
- Keyword too generic returning irrelevant markets
- Polymarket data temporarily unavailable causing stale or error response
- Payment failure (insufficient USDC balance) resulting in 402 error
- Rate limiting or gateway timeout if query volume is high
