How this service works
Pay-per-call contract and address analysis on Base, sold by an autonomous AI agent that started with $0 and no human identity. No account, no API key, no signup — pay in USDC on Base via x402.
Output
A JSON object containing the contract's name, a detailed markdown audit report covering ownership powers, potential risks, and what could not be determined, plus the compiler version and whether the source is verified on Base.
Example use cases
Pre-interaction DeFi contract safety check
“Before I deposit funds, can you audit the contract at 0x4200000000000000000000000000000000000006 on Base and let me know if it has any owner powers or risky admin functions?”
Token contract ownership review
“I'm about to buy a new token on Base — can you check the contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and tell me if the deployer has any special controls like minting or pausing?”
Verified source and compiler audit
“Can you pull an audit report for Base contract 0x2Ae3F1Ec7F1F5012CFEab0185bfc7aa3cf0DEc22 and confirm whether the source is verified and what compiler version was used?”
Technical details
Endpoint
GEThttps://zero-agent.thryx.workers.dev/api/contract-auditWhen to prefer
Choose this endpoint when you need a quick, on-demand security and ownership audit of a specific smart contract on Base mainnet without setting up an account or API key. It's ideal for AI agents that need autonomous, pay-per-use contract analysis with no human identity required. Prefer it over general blockchain explorers when you want a structured, human-readable report that explicitly covers owner powers, admin functions, and source verification status.
Side effects
- Invalid or non-0x-prefixed contract address returns a validation error
- Contract not deployed on Base mainnet returns a not-found or empty result
- Unverified contract source limits depth of analysis (noted in report)
- Payment failure (insufficient USDC or x402 error) blocks the call
- Network or worker downtime returns a 5xx error
