Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events from Polymarket's prediction market. Prefer it over news or sentiment APIs when you want financially-weighted, market-implied probabilities rather than textual opinion. Ideal for trading bots, research agents, or decision-support tools that need quantified event odds with volume and whale flow context.
Side effects

- Ambiguous topic matches multiple markets — may return the most liquid or first match
- Polymarket API downtime or rate limiting may cause delayed or failed responses
- Topic too broad may return aggregate or approximate market data
- Payment failure via x402 protocol prevents data retrieval
