MtGox/API

2011-11-26T18:27:03Z

Btcbuy:

The [[MtGox]] API provides various methods to access different informations from the market, place orders, and more.

Two APIs are available at this point: the HTTP api (available by posting to mtgox.com/code/*) and the websocket API.

==Number Formats==

In the "old API", currency- and amount-values (price, volume,...) were given as '''float'''. These values are likely being deprecated and replaced by fields of the same name with "_int" as suffix. These are '''fixed-decimal''', so you have to move the decimal point yourself (divide). The exponent differs based on the kind of the value.

In order to convert the '''int''' to a '''decimal''' you can...

{| class="wikitable"
|-
! kind of field !! ...divide by !! ...multiply by
|-
| BTC (volume, amount) || 1E8 (10,000,000) || 0.00000001
|-
| USD (price) || 1E5 (100,000) || 0.00001
|-
| JPY (price) || 1E3 (1,000) || 0.001
|}

Implementation advice: it's probably best to use '''int''' or '''Decimal''' (if your language/db offers such a type) in your clients. Using '''float''' will likely lead to nasty rounding problems.

== Currency Symbols ==
List of the currency symbols available with the API:

USD, AUD, CAD, CHF, CNY, DKK, EUR, GBP, HKD, JPY, NZD, PLN, RUB, SEK, SGD, THB

== HTTP API ==
This API is available in <nowiki>https://mtgox.com/api/*</nowiki>, and provides various informations. It also supports making an order, a withdraw, a deposit, etc. There is also a [https://rubygems.org/gems/mtgox Ruby gem] and [[Finance::MtGox|Perl module]] for interacting with the HTTP API.

=== Authentication ===

Authentication is performed by signing each request using HMAC-SHA512. The request must contain an extra value "nonce" which must be an always incrementing numeric value. A reference implementation is provided here:
<source lang="php">
<?php

function mtgox_query($path, array $req = array()) {
// API settings
$key = '';
$secret = '';

// generate a nonce as microtime, with as-string handling to avoid problems with 32bits systems
$mt = explode(' ', microtime());
$req['nonce'] = $mt[1].substr($mt[0], 2, 6);

// generate the POST data string
$post_data = http_build_query($req, '', '&');

// generate the extra headers
$headers = array(
'Rest-Key: '.$key,
'Rest-Sign: '.base64_encode(hash_hmac('sha512', $post_data, base64_decode($secret), true)),
);

// our curl handle (initialize if required)
static $ch = null;
if (is_null($ch)) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MtGox PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
}
curl_setopt($ch, CURLOPT_URL, 'https://mtgox.com/api/'.$path);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

// run the query
$res = curl_exec($ch);
if ($res === false) throw new Exception('Could not get reply: '.curl_error($ch));
$dec = json_decode($res, true);
if (!$dec) throw new Exception('Invalid data received, please make sure connection is working and requested API exists');
return $dec;
}

// example 1: get infos about the account, plus the list of rights we have access to
var_dump(mtgox_query('0/info.php'));

// old api (get funds)
var_dump(mtgox_query('0/getFunds.php'));

// trade example
// var_dump(mtgox_query('0/buyBTC.php', array('amount' => 1, 'price' => 15)));

== Streaming API ==
Real time streaming data may be obtained over the streaming API, implemented in [http://socket.io/ Socket.io]<ref>Socket.io forum announcement by MagicalTux: https://bitcointalk.org/index.php?topic=14412.msg613271#msg613271</ref>. The original WebSocket API<ref>Original WebSocket thread: https://bitcointalk.org/index.php?topic=5855.msg86219</ref> is deprecated as of 11-Nov-2011.

===Connecting===
The following JavaScript code establishes a connection in the browser:
<source lang="javascript">
<script src="https://socketio.mtgox.com/socket.io/socket.io.js"></script>
<script>
var conn = io.connect('https://socketio.mtgox.com/mtgox');
conn.on('message', function(data) {
// Handle incoming data object.
});
</script>
</source>

===Handling Events===
Socket.io exposes a simple interface for handling events. Handling <tt>message</tt> events is shown above, but there are other events that may be handled:
<source lang="javascript">
conn.on('connect', onConnect);
conn.on('disconnect', onDisconnect);
conn.on('error', onError);
conn.on('message', onMessage);
</source>

===Incoming Data===
Data arrives as a full object instead of as JSON text, eliminating the need to parse the data in the JavaScript handler. Messages that come across the socket to trigger the <tt>message</tt> event will contain the following minimum components:
<source lang="javascript">
{
"op":<OPERATION_TYPE>
}
</source>

The <tt>OPERATION_TYPE</tt> field may take a few values:

:{| class="wikitable"
|-
! OPERATION_TYPE !! Description
|-
| subscribe || Notification that the user is subscribed to a channel
|-
| unsubscribe || Messages will no longer arrive over the channel
|-
| remark || A server message, usually a warning
|-
| private || The operation for depth, trade, and ticker messages
|}

===op:subscribe and op:unsubscribe===
The subscribe and unsubscribe message data are very simple, containing the channel and the operation.
<source lang="javascript">
{
"channel":<CHANNEL_ID>,
"op":"subscribe" OR "unsubscribe"
}
</source>

Some of the channels are:

:{| class="wikitable"
|-
! Channel ID !! Description
|-
| dbf1dee9-4f2e-4a08-8cb7-748919a71b21 || Trades
|-
| d5f06780-30a8-4a48-a2f8-7ed181b4a13f || Ticker
|-
| 24e67e0d-1cad-4cc0-9e7a-f8523ef460fe || Depth
|}

===op:remark===
The remark operation contains message and success fields.
<source lang="javascript">
{
"op":"remark",
"message":<MESSAGE FROM THE SERVER>,
"success":<boolean>
}
</source>

===op:private===
The payloads of the <tt>op:private</tt> messages contain the real time market information. Each message follows this form:

<source lang="javascript">
{
"channel":<CHANNEL_ID>,
"op":"private",
"private":<MESSAGE_TYPE>,
<MESSAGE_TYPE>:<DATA_PAYLOAD>
}
</source>

The <tt>MESSAGE_TYPE</tt> field may take the values:

:{| class="wikitable"
|-
! MESSAGE_TYPE !! Description
|-
| ticker || Ticker messages
|-
| trade || Trades, as they occur
|-
| depth || Orders placed or removed
|}

====Ticker====
Ticker messages contain the current inside Bid and Ask as well as daily highs, lows, and volume. The fields contained in the ticker match those defined in the version 1.0 API above. All fields contain <tt>currency</tt>, <tt>display</tt>, <tt>value</tt>, and <tt>value_int</tt> entries.
<source lang="javascript">
