Nano (XNO) API Documentation

Nano

Nano (XNO) is a payments network using Open Representative Voting and a block-lattice architecture in which each account maintains its own blockchain rather than competing for a single global block sequence. Nano has no general-purpose smart contract VM; nodes validate account-chain blocks, tally representative votes, cement confirmed transactions, and maintain balances, representatives, receivable entries, and ledger state. This asynchronous account-chain model makes accounts, blocks, representatives, confirmation status, and receivable transactions the primary integration primitives.

Nano API Methods and Endpoints

NOWNodes exposes Nano's interface, plus a few others, depending on what your integration needs: its native node RPC for account, ledger, representative, block, receivable, and transaction-processing operations. Archive mode extends any of these to historical states and data beyond standard retention.

Browse the interfaces below for endpoint details, request parameters, response formats, and integration examples. Create an API key, select Mainnet or Testnet, choose the required interface, and start sending requests from your application.
