How this service works
Verified smart contract source and ABI summary from Blockscout - compiler, proxy, read and write function counts, payable functions and owner-style functions to review
Output
A JSON object containing the contract's verification status, compiler version, programming language, license, main file name, proxy type, and an ABI summary object with counts of total functions, read functions, write functions, payable functions, owner-style functions, events, and whether a constructor is present. Also includes the chain and data source attribution.
Example use cases
Pre-audit contract function review
“Before I interact with this DeFi protocol, can you check the smart contract at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 on Ethereum and tell me how many payable and owner-style functions it exposes?”
Proxy contract detection on Base
“Is the contract at 0x4200000000000000000000000000000000000010 on Base a proxy contract? If so, what proxy type is it and is the source verified?”
Arbitrum contract language and compiler check
“I need to know what compiler version and language were used for the contract at 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum — and is the source verified on Blockscout?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/contract-source?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, structured summary of a smart contract's ABI and source metadata without parsing raw Solidity files or querying Blockscout directly. It is ideal for pre-interaction security reviews, automated contract auditing pipelines, or agent workflows that need to classify contracts by function type (read/write/payable) across multiple EVM chains including Ethereum, Base, Optimism, Arbitrum, Polygon, and Gnosis.
Side effects
- Contract address not found or not deployed on the specified chain — returns unverified or empty result
- Invalid 0x address format — likely returns an error or empty response
- Contract exists but source is not verified on Blockscout — verified field will be false with limited ABI data
- Unsupported chain name supplied — may default to Ethereum or return an error
- Network or upstream Blockscout API outage — service unavailable
