Technical details
Endpoint
GEThttps://2s.io/api/predict/priceWhen to prefer
Use this endpoint when you need the real-time market-implied price or probability for a specific CLOB prediction market outcome token and have the token ID available. Prefer this over general price APIs when dealing specifically with prediction market outcome tokens rather than standard crypto or equity assets.
Side effects
- Missing or invalid tokenId returns an error or empty result
- Token ID not found in the CLOB system returns a 404 or null price
- Payment failure (USDC/x402) results in 402 Payment Required before data is returned
- Network timeout or upstream data unavailability returns a 5xx error
