The [Node API](/docs/reference/node-api-overview) gives you low-level access to standard JSON-RPC methods for interacting with blockchains.

Use it for sending transactions, querying blocks and logs, and accessing state. It supports multiple chains; see the [Chain APIs Overview](/docs/reference/chain-apis-overview) page for the full list.
