Endpoint
POSThttps://coinrailz.com/x402/polymarket-oddsWhen to prefer
Use this endpoint when you need real-time odds or probability data for a specific, already-known Polymarket event. Prefer this over the search endpoint when you already have the event identifier and want precise, current market data for that single event rather than browsing multiple markets.
Side effects
- Invalid or unrecognized Polymarket event ID returns an error
- Event no longer active or resolved returns stale or empty data
- Payment of 0.5 USDC not completed results in 402 payment required error
- Rate limiting or network issues may cause timeout
