Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/prediction-markets?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for specific future events — especially macro, crypto, political, or AI topics — and want to go beyond simple news or social sentiment by accessing actual financial market orderbook data from Polymarket. Prefer this over social sentiment APIs when you want monetarily-weighted crowd forecasts rather than opinion counts.
Side effects
- Topic keyword returns no matching Polymarket market — empty or null result set
- Polymarket API upstream outage causes stale or unavailable data
- Ambiguous topic string matches multiple markets with conflicting results
- Payment failure via x402 prevents endpoint access
- Rate limiting if too many queries are made in rapid succession
