How this service works

Fetches recently resolved prediction markets from Polymarket and Manifold over the last N days (max 30). Includes question, winning outcome, final prices/probabilities, resolution timestamp, and resolution source. Optional keyword filter. Information only, not financial advice.

Output

Returns a JSON object with a count of resolved markets, the lookback period, source venues checked, a timestamp, and an array of resolved market objects — each containing the market ID, URL, slug, venue name, question text, final outcome prices per outcome, resolution timestamp, winning outcome label, and resolution source URL.

Example use cases

Post-event outcome verification

“Show me all prediction markets that resolved in the last 3 days about the US election so I can see what the markets concluded.”

Sports betting result recap

“Fetch up to 50 resolved sports prediction markets from the past day across Polymarket and Manifold — I want to see which teams or players won.”

Weekly forecasting digest

“Get me the last 30 days of resolved prediction markets, limit to 50 results, and filter by the keyword 'AI' so I can track how AI-related forecasts have been resolving.”

Technical details

Endpoint

GEThttps://api.sitecheck-api.workers.dev/api/pm/resolved?utm_source=zero.xyz

When to prefer

Use this endpoint when you need ground-truth resolution data from multiple prediction market venues in a single call, with optional keyword filtering. Prefer it over scraping individual venue APIs directly when you want aggregated Manifold + Polymarket results with consistent schema, outcome labels, and resolution sources in one response.

Side effects

Invalid or out-of-range 'days' parameter (must be 1–30) may return an error or empty results
Limit exceeding 50 will be capped or rejected
Upstream venue APIs (Manifold, Polymarket) may be temporarily unavailable, surfaced in 'venuesUnavailable' field
Keyword filter returning zero matches yields empty resolvedMarkets array
Network timeout from the Cloudflare Worker to upstream sources
