Example use cases
Gauge whale sentiment before betting
“Before I place a trade on this Polymarket market, can you check whale activity for condition 0xabc123...def456 — specifically whether whales are piling into YES or NO, and what the net flow looks like over the past week?”
Detect unusual large-trader accumulation
“I think something is happening on this Polymarket question — can you pull the whale data for condition 0xdeadbeef...1234 and tell me if there's been a spike in unique whale wallets or abnormally large volume in the last 7 days?”
Research prediction market before publishing analysis
“I'm writing a report on this Polymarket election market. Grab all the whale trading data for condition 0x9999...aaaa — I need aggregate volume, the YES/NO breakdown, net flow, and as many individual whale trades as possible.”
Technical details
Endpoint
GEThttps://api.predge.io/v1/whales/market/:conditionIdWhen to prefer
Use this endpoint when you need detailed, aggregated whale trading intelligence for a specific Polymarket prediction market — particularly when assessing smart-money positioning, YES/NO sentiment, or net flow before making a trade or publishing analysis. Prefer it over generic on-chain analytics when you need Polymarket-specific whale heuristics and wallet scoring context.
Side effects
- Invalid or malformed conditionId (not a valid 0x Polymarket condition hash) returns an error
- No whale activity found for the specified market returns empty trade list
- Market does not exist on Polymarket returns not found error
- Payment not included or insufficient USDC results in 402 payment required
- Rate limiting if too many requests are made in quick succession
