Technical details
Endpoint
GEThttps://x402-api-production-266e.up.railway.app/v1/bets/biggestWhen to prefer
Use this endpoint when you need a cross-market view of the single largest trades by notional value on Polymarket, rather than per-market or per-wallet analysis. Prefer this over /whales/latest when you specifically want size-ranked ordering rather than recency, and over market-specific endpoints when you want to survey all markets at once.
Side effects
- Invalid window parameter (not '24h' or '7d') returns a 400 or validation error
- Payment failure or insufficient USDC balance returns a 402 error
- Service unavailability or railway deployment downtime returns a 503
- Empty result set if no qualifying trades exist in the window (unlikely for 24h)
- Stale data if Polymarket data pipeline is delayed beyond the 15-minute window
