What It Does
Submit a verified contract address (any major chain) or paste Solidity source code. You get a written security review covering:
- Vulnerabilities
- Logic errors
- Access control issues
- Gas optimization notes
- Severity ratings and fix recommendations

Workflow
1. POST /api/audit → HTTP 402 with payment terms
2. Sign EIP-3009 TransferWithAuthorization (USDC, Base, gasless)
3. Retry with PAYMENT-SIGNATURE header → 200 with jobId
4. Poll GET https://onedollaraudit.com/api/jobs/<jobId> until status: "complete"
5. Access reportUrl for the full audit report
Important: Persist jobId immediately after payment. Never re-pay to re-check — recover jobId via trackUrl or on-chain events.
