How this service works
Real-time alerts on whale traders on Polymarket. Heuristic Insider Watch, wallet scoring 0–100, Bloomberg-style web terminal. Free plan included.
Output
A JSON object containing the wallet's Predge score (0–100), rank among all scored wallets, win rate, verdict label (e.g. 'verified_smart_money'), conviction score, edge lower bound, average entry price, total volume in USD, trade counts, and a fully signed ed25519 attestation payload that can be verified offline using the provided public key and canonical JSON string. Also includes a boolean 'clears_bar' indicating if the wallet meets smart-money thresholds.
Example use cases
Vet a whale before copy-trading
“Before I copy this Polymarket trader, can you pull their Predge attestation for wallet 0xabc123...def456 over the last 30 days and tell me their win rate, conviction score, and whether they're classified as verified smart money?”
On-chain proof of trading edge
“I need a cryptographically signed Predge attestation for my wallet 0x8dab6cf42d7e4d1cd6cca897b9e12a8cbe6d69e8 that I can share with an investor — get me the 30-day track record with the ed25519 signature so they can verify it offline.”
Filter signal feed by trader quality
“Check Predge's 7-day attestation for Polymarket wallet 0x1234567890abcdef and tell me their score out of 100 and rank — I only want to follow alerts from wallets scoring above 75.”
Technical details
Endpoint
GEThttps://api.predge.io/v1/wallets/%7Baddress%7D/attest?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a verifiable, cryptographically signed credential proving a Polymarket wallet's trading track record — specifically for copy-trading vetting, on-chain reputation proofs, or smart-money signal filtering. Prefer this over generic wallet analytics when you need an offline-verifiable attestation (ed25519 signature) rather than a raw data lookup, or when you need a standardized verdict label like 'verified_smart_money' to gate access or rank traders programmatically.
Side effects
- Wallet address not found or has no resolved Polymarket trades — returns found:false with no attestation payload
- Invalid wallet address format returns a 4xx error
- Window parameter value outside allowed enum (7d/30d) returns a validation error
- Wallet has insufficient trade history to score reliably — may return low conviction score or partial data
- Payment not received or underpaid (x402 protocol) — returns 402 Payment Required
