How this service works
Wallet & Token Risk Score: Behavioral on-chain risk score (0-100) for a wallet or token contract: activity, age, counterparty concentration, asset diversity and large-transfer share, plus a smart-money score for wallets. Not sanctions or honeypot screening. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/wallet_token_risk.
Output
A structured JSON response containing a behavioral risk score from 0 to 100 for the queried address, plus sub-scores and signals including activity level, wallet age, counterparty concentration, asset diversity, large-transfer share, and (for wallet subjects) a smart-money score. Higher scores indicate greater risk.
Example use cases
DeFi wallet due diligence check
“Before I send funds to this wallet 0xABC123...F00 on Base, can you score its on-chain behavioral risk and tell me whether it looks like a smart-money wallet?”
New token contract safety assessment
“I'm about to buy this token on Arbitrum — its contract address is 0xDEF456...A99. Can you give me a risk score for it as a token contract so I know if anything looks suspicious about its transfer patterns?”
Counterparty risk screening for a DeFi protocol
“We're onboarding a new liquidity provider on Polygon with wallet 0x789GHI...B12 — can you run an on-chain behavioral risk assessment on it, sampling up to 100 transfers, and flag if the counterparty concentration or large-transfer share looks off?”
Technical details
Endpoint
POSThttps://x402.freeq.one/tools/wallet_token_risk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, affordable behavioral risk score for a specific wallet or token contract on EVM chains (Ethereum, Arbitrum, Base, Polygon, Optimism) and do NOT need sanctions screening or honeypot detection. Ideal for DeFi due diligence, counterparty vetting, or token pre-trade checks where pay-per-call pricing ($0.05 USDC) beats subscription-based alternatives. Prefer alternatives if you require OFAC/sanctions compliance or honeypot-specific analysis.
Side effects
- Invalid or malformed address (not 0x-prefixed, not 42 chars) returns a validation error
- Unsupported chain key returns an error — only eth, arb, base, polygon, opt are valid
- Insufficient on-chain data for very new or inactive addresses may yield incomplete scores
- Payment failure via x402 (insufficient USDC balance on Base) blocks the call
- transfer_limit out of range (less than 1 or greater than 100) returns a parameter error
