Contract Source

by Verified contract source in Onchain & crypto

x402 APIPassing, checked 4 h ago

Fetch the verified Solidity source files and compiler metadata for a contract address from Sourcify's open verification repository. Covers 8 EVM mainnets (ethereum, base, polygon, arbitrum, optimism, bsc, gnosis, celo). Contracts that were never verified return a structured {verified:false} miss, not an error. Feed the returned source into /api/solidity-scan for a heuristic pattern check.
