XAPI PROTOCOL DOCUMENTATION

Version 2.5.0

Introduction

This document presents information on API communication protocol. The communication protocol of the API uses JSON format.

JSON format used by the server doesn't allow extensions (e.g. comments, other flags). JSON format standardization document is available under the following link: http://tools.ietf.org/html/rfc4627.

The connection is performed by clean socket connection. For real trading SSL connection will be used.
Definitions

The following definitions will be used in this specification document:
- simple type: type, which value is itself: int, int64, string, double, bool;
- j-value (JSON value): any simple type, j-object or j-array;
- j-object (JSON object): a record containing any number of named j-values (pair );
- j-array (JSON array): an array where each element is j-value;
- j-subvalue: j-value which is a component of a j-object.
A j-object can contain zero elements. A j-array can have zero length. The name of j-value can be an empty string.

Encoding of strings is set to UTF-8. In this format the server sends and receives data.

Definition of unix-time:
```
Unix time, or POSIX time, is a system for describing points in time, defined as the number of milliseconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970.
```
General data format

Each packet consists of exactly one main, unnamed j-value. The data stream consists of consecutive j–values, with no punctuation.

The main j-value is a j-object containing exactly two j-subvalues which are j-objects. The first j-subobject is named header and consists of at least a field type as a simple type string. This is a packet type. The second j-subobject of the main packet j-object is named data and its content is specific to a given packet type. The specifications for different types of packages are described in the next chapter.

A sample of properly defined packet:
```
{
	"command" : "login",
	"arguments" : {
		"userId" : "1000",
		"password": "PASSWORD"
	}
}
```
Every single command sent to the API is allowed to contain an optional field called customTag. The API guarantees to return the very same customTag in the command’s response. For example, the following command:
```
{
	"command" : "login",
	"arguments" : {
		"userId" : "1000",
		"password": "PASSWORD"
	},
	"customTag": "my_login_command_id"
}
```
returns (in case of a successful login):
```
{
	"status": true,
	"customTag": "my_login_command_id"
}
```
Communication with the API

X Open Hub Clients:

Host:
There are two addresses (that can be used interchangeably)
- xapia.x-station.eu
- xapib.x-station.eu
Here are the details of DEMO and REAL servers hosted on each of the addresses above:
- DEMO: main port: 5124, streaming port: 5125,
- REAL: main port: 5112, streaming port: 5113.
Furthermore, WebSockets can be used to connect to the API using the following addresses:
- wss://ws.xapi.pro/demo
- wss://ws.xapi.pro/demoStream
- wss://ws.xapi.pro/real
- wss://ws.xapi.pro/realStream
All servers use SSL connection.

Communication is established as long as both server and client have opened and connected sockets.

For convenience server guarantees that every separate reply to client command returned by server will be separated by two new line characters ("\n").
1. Connection validation
  
  In order to provide best service for all users API set rules on connection and data send process. If any of the following rules is breached, then connection is closed immediately without server notification.
  
  List of rules:
  - At most 50 simultaneous connections from the same client address are allowed (an attempt to obtain the 51st connection returns the error EX008). If you need this rule can be lenified please contact the xStore Support Team.
  - Every new connection that fails to deliver data within one second from when it is established may be forced to close with no notification.
  - Each command invocation should not contain more than 1kB of data.
  - User should send requests in 200 ms intervals. This rule can be broken, but if it happens 6 times in a row the connection is dropped.
  - Each command should be a proper JSON object.
  Exception:
  
  If the client sends a request that is a valid JSON object, but does not conform to the published API (incorrect command, missing fields, etc.), the response is sent back with the error description but the connection is not closed.
  
  This rule prevents incorrect messages from reaching further down the processing chain and allows clients to analyze and understand the source of problem.
2. Default login credentials
  
  Default login credentials can be obtained at: http://developers.xstore.pro/panel/.
3. Input data format
  
  The input data format is a JSON object that consists of service name and command name. Some commands also require an object of command's arguments.
  
  If optional prettyPrint field is set to true, an output JSON is printed in human-readable format. prettyPrint field can be omitted.
```
{
	"command": "commandName",
	"arguments": {
		"arg1Name": 10,
		"arg2Name": "Some text",
		...
	},
	"prettyPrint": true
}
```
4. Output data format
  
  The output data format is a JSON object that consists of status and returnData fields if command succeeded, or status, errorCode and errorDescr fields if an error occurred.
```
{
	"status": true,
	"returnData": JSON value
}
```
  or, in case of an error:
```
{
	"status": false,
	"errorCode": "E123",
	"errorDescr": "Error description"
}
```
5. Time format
  
  Time is number of milliseconds from 01.01.1970, 00:00 GMT.
6. Floating number format
  
  In all Floating numbers '.' (period) is used as a decimal separator.

Available commands

Request-Reply commands are performed on main connection socket. The reply is sent by main connection socket.

Login

In order to perform any action client application have to perform login process. No functionality is available before proper login process.

After initial login, a new session is created and all commands are executed for a logged user until he/she logs out or drops the connection.

Request:

Parameters:
Name Type Desc
userId String userId
password String password
appId String (optional, deprecated)
appName String (optional) application name
Example:
```
{
	"command": "login",
	"arguments": {
		"userId": "1000",
		"password": "PASSWORD",
		"appId": "test",
		"appName": "test"
	}
}
```
After successful login the system responds with the status message that can contain the String representing streamSessionId field:
```
{
	"status": true,
	"streamSessionId": "8469308861804289383"
}
```
The streamSessionId field of the string type, if present, is a token that can be used to establish a streaming subscription on a separate network connection. streamSessionId is used in streaming subscription commands.

streamSessionId is unique for the given main session and will change between login sessions.
Logout

Format of input:
```
{
	"command": "logout"
}
```
No returnData field in output. Only status message is sent.

Command: getChartLastRequest

Description: Please note that this function can be usually replaced by its streaming equivalent getCandles which is the preferred way of retrieving current candle data. Returns chart info, from start date to the current time. If the chosen period of CHART_LAST_INFO_RECORD is greater than 1 minute, the last candle returned by the API can change until the end of the period (the candle is being automatically updated every minute).

Limitations: there are limitations in charts data availability. Detailed ranges for charts data, what can be accessed with specific period, are as follows:

PERIOD_M1 --- <0-1) month, i.e. one month time
PERIOD_M30 --- <1-7) month, six months time
PERIOD_H4 --- <7-13) month, six months time
PERIOD_D1 --- 13 month, and earlier on

Note, that specific PERIOD_ is the lowest (i.e. the most detailed) period, accessible in listed range. For instance, in months range <1-7) you can access periods: PERIOD_M30, PERIOD_H1, PERIOD_H4, PERIOD_D1, PERIOD_W1, PERIOD_MN1. Specific data ranges availability is guaranteed, however those ranges may be wider, e.g.: PERIOD_M1 may be accessible for 1.5 months back from now, where 1.0 months is guaranteed.

Example scenario:

request charts of 5 minutes period, for 3 months time span, back from now;
response: you are guaranteed to get 1 month of 5 minutes charts; because, 5 minutes period charts are not accessible 2 months and 3 months back from now.
