Chain Address Intel

by FiatDock in Weather & location

x402 APIPassing, checked 1 h ago

Address intelligence on Base — EOA/contract/ERC-20 + nonce + ETH/USDC balance + keyless GoPlus security verdict (phishing/sanctioned/mixer/…). The loop input for triaging a counterparty. Pay-per-call via x402. An empty body is answered for the wallet that pays (the payment's signer); send {"address":"0x…"} for any other address.
