How this service works
Paid Base token, wallet, DeFi, chain-read, x402 buyer/seller discovery, and specialized Bitcoin 15-minute Up/Down prediction-market data packets for autonomous agents and risk tools.
Output
Returns a JSON object with a comprehensive wallet risk profile including: wallet trust verdict and safety decision, value-at-risk summary, approval exposure details, counterparty flow analysis, risk breakdown and address risk score, evidence ladder, priority/review/avoid queues, approval revocation recommendations, buyer/seller execution plans, and source status metadata. Also includes a not_financial_advice disclaimer.
Example use cases
Pre-transaction counterparty safety check
“Before I send 5000 USDC to 0xba76c7ECa175f67cFcE475c09498f840176bf497 on Base, can you pull their wallet risk verdict, check their counterparty flow, and tell me if there are any red flags I should know about?”
DeFi approval audit for a wallet
“Run a full approval exposure audit on Base wallet 0x1234567890abcdef1234567890abcdef12345678 for USDC token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — I want to see which spenders are approved, what's at risk, and whether any approvals should be revoked.”
Autonomous agent buyer trust scoring
“I need to verify whether wallet 0xAbCdEf1234567890AbCdEf1234567890AbCdEf12 is a trustworthy buyer before my agent accepts their x402 payment — give me the wallet trust verdict, risk breakdown, and buyer next action recommendation for the last 2000 blocks.”
Technical details
Endpoint
GEThttps://x402.xx402.icu/api/base-wallet-risk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, structured risk verdict for a specific Base/EVM wallet before executing a DeFi transaction, accepting a payment, or onboarding a counterparty. It is especially valuable for autonomous agents that need machine-readable trust scores, approval exposure lists, and actionable next-step queues. Prefer it over generic blockchain explorers when you need opinionated safety decisions and revocation recommendations rather than raw transaction data.
