How this service works
Wallet reputation and trading-signal detection for Polymarket prediction markets -- combining smart-money wallet tracking, insider-pattern detection, and a custom ML edge model. Wallet reputation scores, per-market wallet flow by persona, a free signal-accuracy track record, and push notifications when a high-confidence signal fires. Pay-per-call via x402 (USDC on Base). Machine-readable pricing: GET /.well-known/x402.
Output
A JSON object containing the wallet's trade and volume statistics, assigned persona tags (e.g. sharp, insider, noise trader), realized PnL, open position count, and conviction/concentration metrics. Does not include per-trade history.
Example use cases
Vetting a wallet before copying trades
“Before I mirror this wallet's position on the election market, can you check their Polymarket reputation — I want their persona tag, realized PnL, and conviction score to see if they're actually a sharp trader?”
Smart money flow research
“I'm researching which wallets in the 'smart money' persona have been active on Polymarket recently — can you pull the reputation profile for wallet 0xdeadbeef and tell me their volume, persona tags, and open position count?”
Insider pattern screening
“This wallet just took a big position on a breaking-news market — can you run a reputation check on 0x9876cafe and flag whether it shows any insider-pattern signals based on their historical behavior?”
Technical details
Endpoint
GEThttps://x402.sashco.ca/wallets/%7Baddress%7DWhen to prefer
Use this endpoint when you need to assess the credibility or category of a specific Polymarket wallet — e.g. to determine if it's a sharp, insider, or noise trader before acting on its positions. Prefer this over general blockchain explorers when you need Polymarket-specific persona classification and PnL context rather than raw on-chain transaction data.
Side effects
- Invalid or malformed wallet address returns a 400 or empty response
- Wallet with no Polymarket history may return minimal or null fields
- Payment failure via x402 (insufficient USDC balance on Base) blocks the call
- Rate limiting or quota exhaustion may return a 429
- Data freshness lag of ~24 hours means very recent trades may not be reflected
