How this service works
27 paid endpoints for trading bots
Output
Returns the on-chain verification status of a smart contract, including whether source code is verified, contract metadata, any detected risk flags, and signals relevant to trading bot decision-making.
Example use cases
Pre-trade contract safety check
“Before my trading bot buys this token, verify that the contract 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum is verified on-chain and doesn't have any obvious red flags.”
DeFi protocol due diligence
“I'm about to interact with a new DeFi protocol — can you check if the contract 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D on Ethereum mainnet has verified source code and any audit signals?”
Automated bot contract screening
“My trading bot found a new token on BNB Chain with contract 0x55d398326f99059fF775485246999027B3197955 — verify the contract and tell me if it's legitimate before we proceed.”

Endpoint
POSThttps://x402-chain-intel.vercel.app/api/contract/verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your trading bot or DeFi agent needs programmatic, pay-per-call smart contract verification without requiring an API key subscription. It is especially useful in automated pipelines where contract legitimacy must be confirmed before executing trades, and when micropayment-based access (x402/USDC) is preferred over traditional API key billing.
Side effects
- Invalid or malformed contract address returns an error
- Unsupported blockchain network returns an unsupported chain error
- Unverified or non-existent contract may return a not-found or unverified status
- Payment failure via x402 protocol results in 402 response before data is returned
- Rate limiting or quota exhaustion returns an error response
- Network timeouts when querying on-chain data
