REST API: information about network participants

https://img.shields.io/badge/auth-required-orange.svg

There are three groups of methods for obtaining information about network participants:

  • addresses – the methods designed to get information about the network members’ addresses or aliases;

  • alias – getting the participant’s address by the alias set for him or the alias by the participant’s address;

  • leasing – the GET leasing/active/{address} query that outputs a list of leasing transactions in which the address or alias was involved as a sender or receiver.

addresses group

The addresses group methods are designed to retrieve information about the network members’ addresses or aliases.

Note

You can also use the gRPC methods of the AddressPublicService service to get information about the network members` addresses.

GET addresses

Obtaining all participants` addresses, whose key pairs are stored in the keystore of the node.

Response example:

GET addresses:
[
  "3NBVqYXrapgJP9atQccdBPAgJPwHDKkh6A8",
  "3Mx2afTZ2KbRrLNbytyzTtXukZvqEB8SkW7"
]

Note

You can also use the GetAddresses gRPC method to obtain all the members` addresses whose key pairs are stored in the node keystore.

GET addresses/seq/{from}/{to}

Obtaining addresses of the participants, which are stored in the keystore of a node in a given range: from the address {from} to the address {to}.

The format of the method response is identical to that of GET addresses.

GET addresses/balance/{address}

Getting the balance for the {address} address or alias.

Response example:

GET addresses/balance/{address}:
{
  "address": "3N3keodUiS8WLEw9W4BKDNxgNdUpwSnpb3K",
  "confirmations": 0,
  "balance": 100945889661986
}

POST addresses/balance/details

Get detailed balance information for the list of addresses or aliases, which is specified as an array in the addresses field when prompted.

Parameters returned in the method response:

  • regular – number of tokens owned directly by the participant (R);

  • available – participant’s total balance, excluding funds leased by the participant (A = R - L);

  • effective – participant’s total balance, including funds leased to the participant and minus funds that the participant himself has leased (E = R + F - L);

  • generating – participant’s generating balance, including leased funds, for the last 1,000 blocks.

Variables in parentheses: L – funds leased by the participant to other participants, F – funds leased by the participant from other participants.

Response example for one address:

POST addresses/balance/details:
[
  {
    "address": "3M4Bxh2VfzKFXqiQB8bDgRfVnPWrZUQ2MEF",

    "effective": 59899999999400000
  }
]

GET addresses/balance/details/{address}

Get detailed balance information for an individual address or alias. The information in the response is identical to the POST addresses/balance/details method.

Response example:

GET addresses/balance/details/{address}:
[
  {
    "address": "3N65yEf31ojBZUvpu4LCo7n8D73juFtheUJ",
    "regular": 0,
    "generating": 0,
    "available": 0,
    "effective": 0
  }
]

GET addresses/effectiveBalance/{address}

Obtaining the total balance of the address or alias, including leased funds.

Response example:

GET addresses/effectiveBalance/{address}:
{
   "address": "3GLWx8yUFcNSL3DER8kZyE4TpyAyNiEYsKG",
   "confirmations": 0,
   "balance": 1240001592820000
}

GET addresses/effectiveBalance/{address}/{confirmations}

Retrieves the balance for address or alias {address} after the number of confirmations >= {confirmations}. The participant’s total balance is returned, including funds leased to the participant.

Response example for confirmations >= 1:

GET addresses/effectiveBalance/{address}/{confirmations}:
{
  "address": "3N65yEf31ojBZUvpu4LCo7n8D73juFtheUJ",
  "confirmations": 1,
  "balance": 0
}

GET addresses/generatingBalance/{address}/at/{height}

Obtaining the address or alias generating balance at the specified block height {height}.

Response example:

GET addresses​/generatingBalance​/{address}​/at​/{height}:
{
  "address": "3NkZd8Xd4KsuPiNVsuphRNCZE3SqJycqv8d",
  "generatingBalance": 1011543800600
}

GET addresses/scriptInfo/{address}

Obtaining data about the script installed on the address or alias.

Parameters returned in the method response:

  • address – address in base58 format;

  • script – script body in base64 format;

  • scriptText – the source code of the script;

  • complexity – complexity of the script;

Script complexity – a number from 1 to 100 representing the amount of computing resources required to execute the script.

Response example:

GET addresses/scriptInfo/{address}:
{
  "address": "3N3keodUiS8WLEw9W4BKDNxgNdUpwSnpb3K",
