Technical details
Endpoint
GEThttps://blockrun.ai/api/v1/surf/prediction-market/polymarket/volumesWhen to prefer
Use this endpoint when you need on-chain Polymarket volume data for a specific market condition and want a simple pay-per-call API without managing Polymarket API credentials directly. Prefer this over direct Polymarket access when working within the BlockRun payment infrastructure (x402/USDC on Base or Solana).
Side effects
- Missing or invalid condition_id returns an error
- Unknown condition_id returns empty or not-found response
- Network or upstream Polymarket API outage causes failure
- Payment failure (insufficient USDC balance) blocks the request
