Technical details
Endpoint
POSThttps://prime-api-seven.vercel.app/api/crypto/contract/verifyWhen to prefer
Use this endpoint when an agent needs to confirm the authenticity or verification status of a smart contract before interacting with it, especially in DeFi or NFT workflows where contract legitimacy is critical. Prefer this over generic blockchain explorers when a pay-per-call, no-API-key solution is needed.
Side effects
- Invalid or malformed contract address returns an error
- Unverified or unknown contract returns a not-found or unverified status
- Network timeout or upstream blockchain API failure
- Missing or empty query parameter returns a validation error
- Contract address exists but belongs to an unsupported chain
