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;

  • 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 was involved as a sender or receiver.

addresses group:

GET /addresses

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

Response example:

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

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}.

Response example:

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

}

POST /addresses/balance/details

Get detailed balance information for the list of addresses, 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:
