> Get address balance in nanotons



## OpenAPI

````yaml GET /api/v2/getAddressBalance
openapi: 3.1.1
info:
  title: TON HTTP API C++
  description: >
    This API enables HTTP access to TON blockchain - getting accounts and
    wallets information, looking up blocks and transactions, sending messages to
    the blockchain, calling get methods of smart contracts, and more.


    In addition to REST API, all methods are available through [JSON-RPC
    endpoint](#json%20rpc)  with `method` equal to method name and `params`
    passed as a dictionary.


    The response contains a JSON object, which always has a boolean field `ok`
    and either `error` or `result`. If `ok` equals true, the request was
    successful and the result of the query can be found in the `result` field.
    In case of an unsuccessful request, `ok` equals false and the error is
    explained in the `error`.


    API Key should be sent either as `api_key` query parameter or `X-API-Key`
