How this service works
Pre-trade safety checks for smart contracts and tokens. All paid routes use the x402 'exact' scheme settling in USDC on Base (eip155:8453). Every 402 carries a signed offer and every 200 a signed receipt (EIP-712) — see /.well-known/x402 -> signing.
Output
Returns a JSON object with the queried chain, contract address, a categorical risk level (e.g. 'low', 'medium', 'high'), and a numeric risk score — enabling agents to programmatically gate or warn before executing trades or interactions with the contract.
Example use cases
Pre-trade token safety check
“Before I swap into this token, can you check if 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum is safe — what's the risk level?”
DeFi protocol contract audit
“I'm about to deposit funds into a new DeFi protocol on Base. Can you scan the contract 0x4200000000000000000000000000000000000006 and tell me the risk score before I proceed?”
Automated portfolio risk monitoring
“Run a safety scan on this Base token contract 0x2Ae3F1Ec7F1F5012CFEab0185bfc7aa3cf0DEc22 and flag it if the risk level comes back anything higher than low.”
Technical details
Endpoint
POSThttps://smartcontractrisk.0xhodhod.xyz/v1/scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a fast, cheap ($0.02), automated pre-trade safety signal for an EVM contract on Base or Ethereum — especially in DeFi automation, portfolio bots, or any workflow where interacting with an unverified contract is a risk. It is ideal for gating trades or alerting users before on-chain actions.
Side effects
- Invalid or non-checksummed contract address returns a 4xx error
- Unsupported chain value (not 'base' or 'ethereum') causes a validation error
- Contract address not found on the specified chain may return an unknown risk result
- Payment failure or insufficient USDC balance on Base triggers a 402 response
- Network timeout or upstream blockchain node unavailability causes a 5xx error
