How this service works
Yes/no safety verdicts an agent runs before it acts: before sending funds (/wallet), buying a token (/token), opening a link (/site) or paying an x402 seller (/x402). Every answer has safe (true/false), verdict (ALLOW, CAUTION, BLOCK) and a one-line reason.
Output
A JSON object containing: `safe` (boolean), `verdict` (ALLOW, CAUTION, or BLOCK), `reason` (one-line human-readable explanation), `flags` (array of flagged issues with severity and detail), `target` (the screened address), `chain`, `check` type, `checked_at` timestamp, and a liability disclaimer. Critical flags like 'stealing_attack' trigger a BLOCK verdict with severity level.
Example use cases
Pre-payment wallet fraud check
“I'm about to send 500 USDC to 0x1234abcd5678ef901234abcd5678ef901234abcd on Base — can you screen that wallet for any theft reports or scam flags before I confirm the transfer?”
Smart contract safety review
“Before I interact with the contract at 0x098B716B8Aaf21512996dC57EB0615e2383E2f96 on Ethereum, can you check if it's been flagged as malicious or involved in any stealing attacks?”
DeFi agent pre-transaction gate
“I want you to automatically screen any wallet or contract address on Arbitrum before you execute any trades on my behalf — if it comes back BLOCK or CAUTION, stop and tell me why.”
Technical details
Endpoint
POSThttps://nojunk-safety-gate.mick8511.workers.dev/wallet?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a fast, structured yes/no safety gate before executing any on-chain action involving a wallet or contract address. It is ideal for autonomous agents that need to enforce a safety policy before fund transfers, token purchases, or smart contract interactions. Prefer this over manual lookups or generic blockchain explorers when you need a machine-readable ALLOW/CAUTION/BLOCK verdict with severity-tagged flags.
Side effects
- Invalid or malformed address format returns an error
- Unsupported chain value outside the allowed enum returns a validation error
- Unknown or unindexed address may return ALLOW with no flags but cannot guarantee safety
- Service unavailability or worker timeout returns no verdict
- Address on wrong chain may produce inaccurate results if chain param is omitted
