Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/polymarket-token-priceWhen to prefer
Use this endpoint when you need real-time best bid or ask price data for a specific Polymarket outcome token without setting up your own CLOB connection. It is ideal for price checks before trading, portfolio valuation, spread analysis, or monitoring prediction market sentiment. Prefer this over building a direct Polymarket CLOB integration when you want a simple pay-per-call REST interface with no API key setup required.
Side effects
- Invalid or unknown token_id returns an error or empty result
- Invalid side value (not 'buy' or 'sell') causes a validation error
- Polymarket CLOB API unavailable causes a timeout or upstream error
- No liquidity on the requested side may return null or zero price
- Malformed request body causes a 400 bad request error
