Example use cases
DeFi Protocol Safety Check
“Before I interact with this yield farming contract at 0xd3CdA913deB6f4967b2Ef3aa68f5A843dFa66de, can you verify it's a legitimate, source-verified smart contract so I know it's not a scam?”
Token Contract Audit Before Investment
“I'm thinking of buying this new token but I want to make sure the contract 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 is verified and not a honeypot — can you check it?”
NFT Collection Contract Verification
“Can you verify the smart contract behind this NFT collection at 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13d and confirm the source code has been validated on the blockchain?”
Technical details
Endpoint
POSThttps://omni-api-cyan.vercel.app/api/crypto/contract/verifyWhen to prefer
Use this endpoint when an agent needs to validate the authenticity and source verification status of a smart contract before executing transactions, investing, or integrating with a DeFi or NFT protocol. Prefer this over generic blockchain explorers when you need a programmatic, pay-per-call API response that can be chained into automated workflows.
Side effects
- Invalid or malformed contract address returns an error
- Contract not deployed on the specified chain returns not found
- Unverified contract returns a negative verification status rather than an error
- Network or RPC timeout causes delayed or missing response
- Unsupported blockchain network returns an unsupported chain error
