## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events backed by actual money — Polymarket odds reflect true financial commitment rather than survey sentiment. Prefer this over news sentiment or analyst forecasts when you want a single implied probability figure for a binary event outcome.

## Known failure modes

- No matching market found for the queried topic — returns empty or null result
- Topic keyword too vague, returning unrelated markets
- Polymarket API outage or rate limit causing upstream failure
- Payment failure via x402 protocol resulting in 402 response before data is returned
- Stale or delayed data if Polymarket orderbook has low liquidity for niche topics
