Technical details
Endpoint
GEThttps://nba-odds-gap.relayhop.workers.dev/v1/nba/odds/pm/553856When to prefer
Use this endpoint when you need the Polymarket-specific implied probability for a known NBA market and already have the Polymarket Gamma market ID. Prefer this over the sibling endpoints when you want raw Polymarket pricing rather than Kalshi odds or the cross-platform divergence comparison.
Side effects
- Invalid or non-existent Gamma market ID returns an error or empty result
- Market no longer active or resolved returns stale or unavailable data
- Polymarket Gamma API downtime causes upstream fetch failure
- Payment not completed results in HTTP 402 rejection
