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 rich JSON object including a risk_level classification, risk_flags list, risk_breakdown detail, counterparty_exposure summary, recent_transfers array, token_balance, account and token metadata, a screening_verdict, trust_go_no_go_checklist, address_trust_plan, counterparty_routing_ticket, buyer_execution_plan, and follow_up_purchase_urls — along with a not_financial_advice disclaimer.
Example use cases
DeFi counterparty trust check
“Before I send USDC to 0xba76c7ECa175f67cFcE475c09498f840176bf497 on Base, can you screen that address for risk flags and give me a trust verdict based on its last 3000 blocks of transfer activity?”
Protocol risk monitoring for new wallets
“A new wallet just connected to my DeFi protocol — can you assess the risk level of 0xba76c7ECa175f67cFcE475c09498f840176bf497 by checking its recent Base USDC transfers over the past 2000 blocks, including counterparty exposure?”
Automated wallet screening pipeline
“Run a risk screen on Base address 0xba76c7ECa175f67cFcE475c09498f840176bf497 using the token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, look at up to 5000 blocks back, and return the full risk breakdown with up to 10 transfer samples.”
Technical details
Endpoint
GEThttps://x402.xx402.icu/api/base-address-risk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, agent-ready risk assessment of a specific Base/EVM wallet address before transacting, routing payments, or onboarding a counterparty. It is particularly suited for autonomous agents that need a go/no-go decision with supporting evidence rather than raw chain data. Prefer it over generic block explorers when you need packaged risk flags, counterparty exposure analysis, and actionable trust plans in a single API call.
