# Aptos Modules API > Inspect the Move smart-contract code published at any Aptos account, live from the official public Aptos fullnode REST API — no key. Where a resources endpoint shows an account's data, this shows its code: list the Move modules an account publishes, read any module's full ABI — its exposed functions with their visibility, entry and view flags, generic type parameters, parameter and return types, plus its struct definitions — and filter straight to the callable entry functions (state-changing transactions) and view functions (read-only queries) a dApp can invoke. The on-chain interface layer for Aptos wallets, explorers, SDK and binding generators, and security tooling that need to know exactly what a contract exposes before calling it. Reads straight from the chain; live, short cache only. ## Authentication All requests require your oanor API key in the `x-oanor-key` header.
