How this service works
Crypto and prediction market intelligence through x402.
Output
Returns whale trades (up to the requested limit), wallet metadata including tier classification and whale score, and recent activity summary for the specified 0x wallet on Polymarket.
Example use cases
Monitor competitor trading patterns
“Can you check what that whale wallet 0xabc123def456... has been trading on Polymarket lately? I want to see if they're making similar bets to us and what their whale score is.”
Validate whale status before partnership
“Is the wallet 0x789fedcba321... actually a recognized Polymarket whale? Pull their tier, score, and recent activity so I can assess if they'd be a good collaborative trader.”
Track major player market moves
“I keep seeing trades from wallet 0xdef456abc789... - can you look up their full Polymarket trading history and tell me what tier whale they are? I want to follow their next big moves.”
Technical details
Endpoint
GEThttps://api.seerium.xyz/v1/prediction/whale-radar/by-walletWhen to prefer
Use this endpoint when you need to profile a specific known wallet address on Polymarket — e.g. you already have the 0x address and want its whale classification, score, and trade history. Prefer this over the top-whales feed endpoint when you need per-wallet detail rather than a ranked leaderboard.
Side effects
- Wallet address not in tracked whale list — returns empty or not-found response
- Invalid 0x address format — schema validation error
- Wallet has no Polymarket activity — returns empty trades array
- limit parameter out of range — validation error
- Payment not fulfilled (x402) — 402 Payment Required response
- Network or upstream data provider outage — 5xx error
