Contract ABI LookupService

contract-abi

Verified contract ABI and compiler facts from Sourcify, with proxy detection. POST JSON {"chain_id": 1, "address": "0x...", "include_abi": true} to /v1/tool, or GET /v1/contract?address=...; chains: Ethereum (1), Optimism (10), BNB Chain (56), Polygon (137), Base (8453), Arbitrum (42161). The response is a JSON object with verified, match (full or partial), contract_name, compiler, language, abi, abi_functions and abi_events (signatures), source_url, is_proxy and proxy_impl (EIP-1967 and legacy zeppelinos slots) and, for a proxy, the implementation's verified facts. An unverified contract returns verified false and no ABI; an address without code returns 404.
