# Sui Modules API > Inspect the Move smart-contract code published in any Sui package, live from a public Sui fullnode JSON-RPC — no key. Sui contracts are published as packages of Move modules; this reads their normalized ABI: list every module in a package, read a module's exposed functions (visibility, entry flag, type parameters with their abilities, parameter and return type tags) and struct definitions, or drill straight into a single function's signature. Unlike object- and coin-readers, this exposes the callable interface itself — exactly what a Sui package lets you do — the layer Sui wallets, explorers, programmable-transaction-block builders and SDK and binding generators need before they can construct a transaction. Reads straight from the chain; live, short cache only. ## Authentication All requests require your oanor API key in the `x-oanor-key` header.
