How this service works
Live Base wallet intelligence paid with USDC via x402
Output
Returns a JSON object with: the queried address, a three-tier verdict (SAFE, CAUTION, or RISKY), a numeric risk score from 0–100, an array of human-readable reasons explaining the verdict, current USDC balance, native ETH balance, current gas price in gwei, the block number at query time, the RPC node used, provenance metadata, and an ISO timestamp.
Example use cases
Pre-transaction counterparty screening
“Before I send 500 USDC to 0xAbCd1234...5678, can you check if that wallet is flagged as risky on Base and give me the risk score and reasons?”
DeFi protocol wallet vetting
“I'm about to interact with a smart contract at 0xDeadBeef...1234 on Base — can you pull a safety verdict on that address and tell me its ETH and USDC balances?”
Automated fraud alert for incoming payments
“Someone just sent me a payment from 0x9876...ABCD — can you check whether that wallet is labeled SAFE, CAUTION, or RISKY and explain why before I release the goods?”

Endpoint
GEThttps://nova5-x402.yesterdays-signal.workers.dev/wallet-decisionWhen to prefer
Choose this endpoint when you need real-time, on-chain wallet risk intelligence specifically on the Base network, with a scored verdict and human-readable reasons — especially in agentic payment flows where you want to gate transactions behind a risk check. Prefer it over generic blockchain explorers when you need a structured SAFE/CAUTION/RISKY classification with an explanation, not just raw transaction history. The micro-payment model ($0.01 USDC via x402) makes it suitable for per-call invocation inside automated agent pipelines without subscriptions.
Side effects
- Missing or malformed wallet address returns a 400-level error
- Payment not provided or insufficient USDC triggers 402 Payment Required before any data is returned
- Invalid EVM address format (non-hex, wrong length) likely returns an error or empty result
- RPC node unavailability may cause delayed or failed responses
- Rate limiting if too many concurrent calls are attempted
