How this service works
A professional AI security review of your smart contract for one dollar. Pay with USDC, ETH, or CLAWD on Base — or via x402 if you're an agent. Tracked on-chain, reviewed on ERC-8004.
Output
Returns a JSON object with a numeric jobId, a link to the audit job page (jobUrl), a statusUrl to poll for completion, an estimated completion time in seconds (~3600), and a message confirming the job was created on-chain. Once complete, the statusUrl returns the full audit report URL. If a callbackUrl was provided, the result is also POSTed there automatically.
Example use cases
Pre-launch DeFi protocol security check
“I'm about to launch my DeFi staking contract — can you send it to One Dollar Audit for a security review? The contract address is 0x4e2A3b1F... verified on Basescan. Ping me back when the report is ready.”
NFT contract audit before mint
“Audit my NFT minting contract source code with One Dollar Audit — here's the Solidity code: [source]. Let me know the job URL so I can track it, and post the result to my webhook at https://myapp.com/audit-callback.”
Third-party contract trust check
“Before I integrate this protocol into my app, can you run a quick AI security audit on their contract at 0x9F33c7... on Etherscan via One Dollar Audit? I want to make sure there are no obvious exploits.”
Technical details
Endpoint
POSThttps://onedollaraudit.com/api/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an affordable, automated AI security review of a smart contract — either by its verified on-chain address or raw source code — and want results tracked on-chain via ERC-8004. Ideal for developers who want a fast, low-cost pre-launch security check without engaging a full manual audit firm. Particularly well-suited for AI agents that can pay via x402 (USDC on Base) and handle async job polling or webhook callbacks.
Side effects
- Payment not received or insufficient — audit job not created
- Invalid or unverified contract address — contract not found on Basescan/Etherscan
- Source code too short (under 10 chars) — rejected as invalid input
- Callback URL is not HTTPS — may be rejected or ignored
- Job polling timeout — audit takes up to 1 hour, polling too early returns pending status
- Network or chain congestion delaying on-chain job registration
