How this service works
3 independent LLM perspectives (security, logic, gas) + static analysis. Returns scored findings.
Output
A JSON response containing an 'ok' status flag, a niche identifier ('code_audit'), a 'result' object with scored findings categorized across security, logic, and gas perspectives from three independent LLM analyses plus static analysis, and a payment receipt object confirming the x402 micropayment transaction.
Example use cases
Pre-deployment DeFi contract security check
“Before I deploy this Solidity lending contract to Ethereum mainnet, can you run a full multi-LLM audit on it — checking for security holes, logic bugs, and gas inefficiencies — and give me scored findings? Here's the source code: [paste source]”
Audit already-deployed verified contract
“Can you audit the Sourcify-verified contract at address 0xABCDEF1234567890 on Polygon and tell me if there are any security vulnerabilities, logic issues, or gas problems? I need scored results.”
Gas optimization review for Vyper contract
“I've written a Vyper contract and I want to know where I'm wasting gas and if there are any logic errors. Can you run a three-perspective AI audit on it — security, logic, and gas — and give me the scored findings? Language is Vyper.”
Technical details
Endpoint
POSThttps://codeaudit.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need multi-angle smart contract auditing that combines both AI-driven reasoning (security, logic, gas perspectives from three independent LLMs) and static analysis in a single call. Prefer it over single-LLM review tools when you want scored, categorized findings and cross-validated results. It accepts either raw source code or a Sourcify-verified on-chain address, making it suitable both for pre-deployment review and post-deployment contract inspection.
Side effects
- Invalid or unparseable Solidity/Vyper source code returns an error finding or null result
- Contract address not found on Sourcify for the specified chain returns a lookup error
- Unsupported chain identifier causes a resolution failure
- Malformed request body missing both source and address fields results in a validation error
- Network timeout on LLM inference may return a partial or empty result object
