Endpoint
GEThttps://polymarket-odds.agentdiet.dev/paid?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction markets for macro, crypto, AI, or geopolitical events. Prefer this over news or sentiment APIs when you want market-implied probabilities backed by actual money rather than sentiment scores or editorial opinion. Ideal for agents doing risk assessment, trading signal generation, or current-events probability tracking.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or no-result response
- Ambiguous topic resolves to wrong market — verify market title in response
- Payment failure via x402 — endpoint returns HTTP 402 if payment not processed
- Polymarket API unavailable or rate-limited — upstream outage may return error
- Topic too vague results in multiple markets returned without clear winner
