How this service works
Hire an AI Ethereum builder. Consults, builds, and audits — pay with CLAWD or USDC on Base.
Output
Returns a JSON object with a numeric jobId, a jobUrl linking to the audit report page on onedollaraudit.com, a statusUrl for polling the job status (JSON), a human-readable message, and an estimatedCompletionSeconds value (~3600s). The audit runs asynchronously; the agent must poll statusUrl or wait for a callback POST to the provided callbackUrl containing jobId, status, reportUrl, and statusUrl.
Example use cases
Pre-deployment contract security check
“Before I deploy my new staking contract, can you audit this Solidity source code for any vulnerabilities or reentrancy issues? Here's the source: `pragma solidity ^0.8.0; contract Staking { ... }`. Send the results to https://myserver.com/audit-done when it's finished.”
Audit a live DeFi protocol contract
“I want to audit the deployed Uniswap V3 pool contract at 0x8f8EF111B67C04Eb1641f5ff19EE54Cda062f163 on Etherscan — can you kick off an AI audit on it and give me a link to track the report?”
Quick security review before token launch
“We're launching an ERC-20 token next week and need a fast security audit on our contract code. Here's the source — can you submit it for an AI audit and notify our webhook at https://launches.mycompany.io/audit-result when it's ready?”
Technical details
Endpoint
POSThttps://leftclaw.services/api/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an affordable ($1 USDC), automated AI-driven security audit of an Ethereum smart contract — either by on-chain address (verified on Basescan/Etherscan) or raw Solidity source code. It is ideal for developers who want a quick pre-deployment review, a second opinion on a deployed protocol, or an asynchronous audit that posts results to a webhook. Prefer alternatives if you need a human auditor, a multi-chain audit beyond Ethereum/Base, or a synchronous real-time response.
Side effects
- Invalid or unverified contract address — Basescan/Etherscan cannot locate the contract
- Source code too short (under 10 characters) — rejected by schema validation
- Payment failure — USDC or CLAWD payment on Base not confirmed via x402
- Invalid callbackUrl — must be an https URL
- Job queue overloaded — long delays beyond estimated completion
- Contract not verified on-chain — address submitted but source not publicly available
