# minia2a AI Smart Contract Security Audit

> minia2a AI Smart Contract Security Audit is a paid API for AI agents from minia2a.uk, paid per call via x402, $20/call, status unknown (last checked 2026-09-14).

Runs a 3x-sampled AI deep audit of smart contracts (Solidity/Rust/Move) across chains, deduplicating findings and flagging business-logic, economic, and cross-contract vulnerabilities

## Facts

- Endpoint: GET https://minia2a.uk/x402/ai-audit
- Price: $20/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/minia2a-ai-smart-contract-security-audit-4c6c4771
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_57t7DFy2tCSojrc0Y0BxW

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability minia2a-ai-smart-contract-security-audit-4c6c4771
```

Example prompt: Can you run a deep AI security audit on my Solidity contract and flag any business-logic flaws, uninitialized owner issues, missing signer authorization, or economic vulnerabilities before I deploy it?

## When to prefer this

Choose this endpoint when you need AI-powered multi-sample smart contract security analysis covering business-logic, economic, and cross-contract flaws beyond simple static pattern matching — especially useful for Solidity, Rust, and Move contracts across multiple chains. Prefer this over the sibling static-pattern audit endpoint when you want deeper semantic analysis with deduplication across three independent AI passes. Note the $20 USDC cost per call and that findings require manual verification for critical issues.

## Known failure modes

- Payment not made or forged payment rejected — endpoint requires $20 USDC via x402 protocol
- Contract code too large or malformed input — may return an error or incomplete analysis
- False negatives — AI may miss real vulnerabilities; not a substitute for manual audit
- False positives — AI may flag non-issues that require manual triage
- Unsupported language or chain — may return limited or no findings for unsupported targets
- Timeout or service unavailability during deep 3x sampling pass

## How this service works

Smart contract security audit, solidity/rust/move vulnerability scan. AI deep audit across chains — 3x sampled, deduplicated. Catches business-logic, economic, cross-contract flaws (uninitialized owner, account confusion, missing signer auth). LIMITATIONS: AI audit is probabilistic — may miss vulnerabilities or report non-issues; treat as guidance, not proof; critical findings require manual verification. Case: minia2a.uk/blog/blog-ai-contract-audit-august-2026.html

## Output

A deduplicated AI-generated security audit report covering vulnerability findings across three independent analysis passes, categorized by type (business-logic, economic, cross-contract, access control, etc.) with severity indicators and descriptions. May include findings for reentrancy, uninitialized owner, account confusion, and missing signer authorization. Results are probabilistic and should be treated as guidance rather than proof of security.
