How this service works
Paid on-chain token, wallet, contract and research data over x402 on Base.
Output
Returns a JSON object with a summary string (e.g. 'No findings'), an array of vulnerability findings each with severity and details, an overall riskScore (numeric), the number of scannedBytes, and a severityOrder array ranking levels from critical down to info. Source attribution is also included.
Example use cases
Pre-deployment DeFi contract audit
“Before I deploy this Solidity liquidity pool contract, can you run a vulnerability scan on it and tell me if there are any critical or high severity issues I should fix first?”
ERC-20 token security check
“I just wrote an ERC-20 token contract in Solidity — can you audit it for common vulnerabilities like reentrancy, integer overflow, or access control issues and give me a risk score?”
JavaScript Web3 script security review
“Can you scan this JavaScript Web3 script for security vulnerabilities? I want to know the risk score and any findings before I put it into production.”
Technical details
Endpoint
POSThttps://coinop.publicvm.com/api/v1/audit/vulnerability-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call on-chain vulnerability scan of Solidity or JavaScript code without a subscription, especially in automated agent pipelines where cost-per-scan control matters. It is well-suited for pre-deployment audits of smart contracts on Base or other EVM chains and returns machine-readable structured findings ideal for downstream agent decision-making.
Side effects
- Empty or malformed source code input returns zero findings with scannedBytes of 0
- Unsupported language value causes fallback to Solidity default or error
- Payment failure via x402 (insufficient USDC balance) results in 402 response before scan executes
- Very large code inputs may time out or return partial results
- Network instability on Base may cause payment confirmation delays
