How this service works
AI-powered smart contract audit checklist matching - analyzes contract code and returns relevant security checklist items. Returns immediately (202 Accepted) with a polling URL. Poll GET {jobStatusUrl} every 5-10 seconds until status is 'completed'. Estimated time: ~90 seconds. PRICING (based on model): DeepSeek: $0.05 USDC, Sonnet: $0.15 USDC, Fable: $0.30 USDC. Payment must match selected model.
Output
Returns a markdown-formatted list of relevant smart contract security audit checklist items matched to the provided contract code, organized by security category (up to the requested number of categories, default 12, max 20). Each category contains specific checks pertinent to the analyzed code.
Example use cases
DeFi protocol pre-audit security check
“I'm about to launch a new DeFi lending protocol. Can you run the audit checklist against my Vault.sol and LendingPool.sol contracts and tell me which security categories I need to address before deployment?”
NFT contract vulnerability review
“I've written an ERC-721 NFT contract called ArtDrop.sol — can you match it against the smart contract security checklist and show me up to 10 categories of issues I should look into?”
DAO governance contract hardening
“We're finalizing our DAO's governance contract in Governor.sol. Can you run it through the AI audit checklist matcher and return all the relevant security checklist items so we can harden it before our community vote?”
Technical details
Endpoint
POSThttps://api.remix.live/mcp/x402-http/get_audit_checklist?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a targeted, checklist-style audit of specific Solidity contract files and want structured security categories in markdown. Prefer this over the full audit report endpoint when you want a lighter-weight checklist overview rather than a comprehensive report, or when you want to quickly identify which security categories apply to your contract before a deeper review. Use the sibling Slither-powered endpoint when you need static analysis with specific vulnerability detection rather than AI-matched checklists.
Side effects
- No contract files provided — requires at least one source file with content
- maxCategories out of range — must be between 1 and 20
- OpenRouter upstream failure — AI model unavailable or rate-limited
- Malformed input schema — sources map missing required 'content' field
- Payment not fulfilled — x402 payment of $0.05 USDC not processed
