How this service works
Complete AI-powered smart contract security audit - analyzes code against checklist and provides detailed findings with severity levels. Returns immediately (202 Accepted) with a polling URL. Poll GET {jobStatusUrl} every 5-10 seconds until status is 'completed'. Estimated time: ~120 seconds. PRICING (based on model): DeepSeek: $0.15 USDC, Sonnet: $0.25 USDC, Fable: $0.70 USDC. Payment must match selected model.
Output
A detailed AI-generated smart contract security audit report that maps the provided source code against the audit checklist, identifying vulnerabilities, their severity, affected code locations, and recommended remediation steps for each finding.
Example use cases
Pre-deployment DeFi protocol audit
“Before I deploy this DeFi lending protocol to mainnet, run a complete security audit on all three Solidity files — LendingPool.sol, InterestModel.sol, and Collateral.sol — and flag any reentrancy, access control, or flash loan vulnerabilities.”
NFT contract vulnerability check
“Can you audit my NFT minting contract MyNFT.sol for security issues? I want to know if there are any weaknesses like integer overflows, unsafe external calls, or ownership exploits before I launch.”
Custom checklist audit for client review
“Run a security audit on this Solidity staking contract StakingRewards.sol using the custom audit checklist I've provided in markdown format, and give me a detailed findings report I can share with my client.”

Endpoint
POSThttps://api.remix.live/mcp/x402-http/do_audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, AI-driven narrative security audit report with checklist-mapped findings, as opposed to purely static analysis (use the Slither-based sibling endpoint for that). Best when you already have or can fetch an audit checklist (e.g. from the companion get_audit_checklist endpoint) and want a human-readable, detailed vulnerability report suitable for client delivery or pre-deployment review.
Side effects
- Missing or empty sources map returns a validation error
- No contract content provided in the sources object
- Invalid or malformed Solidity code may produce incomplete analysis
- Checklist not provided results in a default or empty checklist being used
- Large or complex contracts may hit processing time or size limits
- Payment of 0.1 USDC via x402 protocol not provided results in 402 Payment Required
