## When to prefer this

Choose this endpoint when you need quick, distilled Polymarket prediction market odds for a specific topic via a micropayment-gated B2A API. It's best suited for agents that need probability signals from prediction markets without scraping Polymarket directly, and that can pay per-call in USDC via x402.

## Known failure modes

- Missing or empty 'topic' query param returns empty or generic data
- Topic not found on Polymarket returns empty data object
- Payment failure via x402/HTTP 402 blocks the response
- Rate limiting or quota exceeded returns an error status
- Stale market data if Polymarket source is not recently synced
