x402 Address-Poisoning Check (Base USDC)

API ↗

x402 Address-Poisoning Check (Base USDC) is a paid API for AI agents from paycheck.hectichustle.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-17).

Checks whether a recipient Ethereum address is a lookalike/poisoning attack relative to a sender's transaction history, returning a risk level and reasons.

How this service works

Address-poisoning check before you send USDC on Base. Body {from, to} (or sender/recipient; chain=base, token=USDC only, others 400 not charged; optional contacts/known_addresses): scans the sender's recent Base USDC transfers for lookalikes (same first/last 4 hex) plus dust/zero-value transfers. No sender? {recipient, known_addresses} = offline contacts check; {address} alone scans its own history for poisoning signs. Returns risk low/medium/high, lookalikes, reasons, coverage.

Output

A JSON object containing: the 'to' and 'from' addresses, a 'risk' field ('low', 'medium', or 'high'), a 'reasons' array explaining the assessment, a 'seenBefore' boolean indicating if the recipient was found in prior transactions, a 'lookalikes' array of any suspicious similar addresses found, and a 'coverage' object describing how many blocks and RPC calls were scanned and what percentage of history was covered.
