Endpoint
GEThttps://blockrun.ai/api/v1/pm/polymarket/markets/:hash/volume?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical cumulative trading volume specifically for a Polymarket prediction market, identified by its on-chain hash. Prefer this over general DeFi volume APIs when your target is a Polymarket contract and you need time-series accumulation data rather than current snapshot only.
Side effects
- Invalid or unknown market hash returns an error or empty data
- Market not found on Polymarket returns a 404 or null response
- Malformed hash format may cause a bad request error
- Network or upstream Polymarket API unavailability causes service errors
- Rate limiting or payment failure (402) if USDC balance is insufficient
