How this service works
Cryptographically SIGNED WALLET TRACK-RECORD attestation (path param: 0x… wallet address; optional query param: window = 7d|30d, default 30d). Returns the wallet's RESOLVED-market-only record — win_rate, Wilson 95% lower bound, edge over entry price, conviction_score, volume, and a verdict (verified_smart_money | positive_edge | no_proven_edge) — as an ed25519-signed envelope verifiable OFFLINE against the SAME published key as /v1/attest. Every other tool shows a self-reported or scraped win rate you must trust; this SIGNS it, so a copy-trading platform, a fund proving a track record to an allocator, or an agent sizing a copy can verify the record without trusting this endpoint. Win rate is computed from resolved markets only (a trade wins when its side equals the market's eventual resolution). 404 (not charged) when the wallet has no resolved trades in the window.
Output
An ed25519-signed JSON envelope containing the wallet's resolved-market trading record: win_rate, Wilson 95% lower bound, edge over entry price, conviction_score, total volume, and a verdict string (verified_smart_money | positive_edge | no_proven_edge). The signature can be verified offline against Predge's published public key. Returns 404 (not billed) if the wallet has no resolved trades in the requested window.
Example use cases
Vet a whale before copy-trading
“Before I copy-trade this Polymarket wallet 0x7f2e...a1b4, can you get me their signed performance attestation for the last 30 days? I want to know their win rate, edge score, and whether they're classified as verified smart money.”
Prove track record to an allocator
“I need to show a fund allocator that wallet 0xd3c1...88fa has a verified edge on Polymarket — can you get the cryptographically signed track-record attestation for the past 30 days so they can verify it offline?”
Agent auto-sizing copy positions
“Check the 7-day signed attestation for wallet 0xa9f0...23cd on Predge — I want the conviction score and verdict so I can decide how much weight to give their current Polymarket positions.”
Technical details
Endpoint
GEThttps://api.predge.io/v1/wallets/:address/attest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need tamper-proof, offline-verifiable proof of a Polymarket wallet's trading performance — not just a scraped or self-reported win rate. Ideal for copy-trading platforms that need to size positions by verified edge, funds presenting auditable track records to allocators, or agents that need to make trust decisions about a trader without relying solely on this endpoint's word. The ed25519 signature distinguishes it from any competing analytics tool.
Side effects
- 404 Not Found — wallet has no resolved trades in the requested window (not charged)
- Invalid wallet address format — malformed 0x address in path
- Unsupported window value — only 7d or 30d are accepted
- Payment failure — x402 payment not completed, request rejected
- Network timeout — endpoint unreachable transiently
