How this service works
Polymarket resolution status via Gamma API — market resolution, winning outcome and resolution source lookup by slug or condition id (or list recent resolved markets). Distinct from live odds: returns whether a market is closed and which outcome won. Coverage Polymarket markets.
Output
Returns whether the specified Polymarket market is closed/resolved, the winning outcome, and the resolution source. When listing, returns up to 50 recently resolved markets with their outcomes and slugs.
Example use cases
Example prompt
“Did the Polymarket market 'new-rihanna-album-before-gta-vi-926' resolve, and if so which outcome won? Use the slug to look it up.”
Technical details
Endpoint
GEThttps://x402-endpoints.onrender.com/polymarket/resolutionWhen to prefer
Use this endpoint when you need to verify the final resolved outcome of a Polymarket market — i.e., which side won and whether the market is closed. This is distinct from live odds or price endpoints; it specifically answers 'did this market resolve and who won?' Use slug or condition_id for a specific market, or omit both to list recent resolutions.
Side effects
- Unknown or invalid slug returns not found or empty result
- Invalid condition_id format returns an error
- Market not yet resolved returns open/unresolved status
- limit out of range (outside 1-50) may be rejected or clamped
- Gamma API upstream outage causes timeout or 5xx error
- Payment not included or insufficient USDC causes 402 rejection
