How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns the verification status of the smart contract including whether source code is verified, contract name, compiler details, and an audit record with a cryptographic chain hash for tamper-evident logging.
Example use cases
DeFi protocol contract audit
“Before we interact with this DeFi protocol, can you verify that the contract at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 is properly verified on Ethereum mainnet?”
Token contract legitimacy check
“I found this token contract address 0x6B175474E89094C44Da98b954EedeAC495271d0F on chain 1 — can you confirm it's a verified contract before I trust it?”
Cross-chain contract verification
“Check if the smart contract 0x1234567890abcdef1234567890abcdef12345678 is verified on Polygon, chain ID 137, and give me any details you find.”

Endpoint
GEThttps://api.strale.io/x402/v2/contract-verify-checkWhen to prefer
Choose this endpoint when you need a fast, auditable, on-chain smart contract verification check with cryptographic audit trail support. Ideal for AI agents performing due diligence on DeFi contracts, token addresses, or any on-chain deployments across supported EVM chains. Prefer this over generic block explorer lookups when you need structured, machine-readable output with audit record hashing.
Side effects
- Invalid contract address format (non-0x or wrong length) returns validation error
- Unrecognized chain ID returns unsupported chain error
- Contract exists on chain but is unverified returns unverified status
- Network timeout or RPC unavailability returns service error
- Contract address not found on specified chain returns not found error
