Technical details
Endpoint
POSThttps://md.fastdb.in/pulse/resolvingWhen to prefer
Use this endpoint when you need to discover Polymarket prediction markets that are about to close, specifically sorted by trading volume. Prefer this over the general odds endpoint when the user's intent is time-sensitive discovery (expiring soon) rather than looking up a specific known market.
Side effects
- No markets found within the specified time window
- Polymarket data temporarily unavailable or stale
- Invalid or missing N (hours) parameter causing a 400 error
- Timeout if Polymarket upstream is slow
