This page is the Ryzom Forge version of api.ryzom.com site

According to Wikipedia, an API or "Application Programming interface" is a computing interface which defines interactions between multiple software intermediaries. It defines the kinds of calls or requests that can be made, how to make them, the data formats that should be used, the conventions to follow, etc. [...]Through information hiding, APIs enable modular programming, which allows users to use the interface independently of the implementation.

In our case: Ryzom API is an URL based system to get some Ryzom in-game information like game time, character, guild profile... API changes log can be found on forum.

Basics

Base URL

All requests are using https://api.ryzom.com as base url.

API keys

• API keys are 41 alphanumeric characters. Character keys start with 'c' and guild keys with 'g'.
• API keys must be created using "RyzomAPI app": https://app.ryzom.com/app_ryzomapi
• You must be guild leader or high officer to manage and view guild api key.

PHP API

PHP API library can be found in the ryzom API client repository.

Third party libraries

(PHP) Sheet translations and info about resources can be found in the https://github.com/nimetu/ryzom_extra repository. The json-resources branch has data in JSON format.

python Interface ?

Functions

Time

To know the time and date in Ryzom.

Usage

<base URL>/time.php

URL Parameters

format

(optional), defaults ro raw.

• raw : Returns the tick. The server tick is a 32 bit integer that increases by one every 100 milliseconds.
• txt : Returns a homine-readable string.
• xml : Returns an xml file that contains all shard time information.

Cache duration

The data is cached for 1 minute.

XML structure

<shard_time>
  <server_tick>514105152</server_tick>
  <jena_year>2576</jena_year>
  <day_of_jy>319</day_of_jy>
  <month_of_jy>10</month_of_jy>
  <cycle>0</cycle>
  <day_of_cycle>319</day_of_cycle>
  <month_of_cycle>10</month_of_cycle>
  <day_of_month>19</day_of_month>
  <day_of_week>1</day_of_week>
  <season>3</season>
  <day_of_season>49</day_of_season>
  <time_of_day>13</time_of_day>
  <txt_en>13h - Dua, Mystia 20, 1st AC 2576</txt_en>
  <txt_fr>13h - Dua, Mystia 20, 1er CA 2576</txt_fr>
  <txt_de>13h - Dua, Mystia 20, 1. AZ 2576</txt_de>
  <cache created="1387437183" expire="1387437243"/>
</shard_time>

PHP interface

ryzom_time_api() : Returns SimpleXMLElement or boolean false on failure.

<?php
  require_once "ryzomapi_lite.php";

  $time = ryzom_time_api('xml');
  if ($time !== false) {
    $txt_en = htmlspecialchars($time->txt_en);
    echo "Atys time is {$txt_en}";
  } else {
    echo "API failure";
  }
?>

Character

Access character information.

Usage

<base URL>/character.php?apikey=key
<base URL>/character.php?apikey[=key1&apikey[]=key2

URL Parameters

apikey

Character API key starting with 'c'

Cache Duration

<character> xml element has attributes *created* and *cached_until* (utc timestamp)

XML structure

API is able to return information about multiple characters at once and so each <character> element is child of <ryzomapi> root element:

<ryzomapi>
  <character apikey="key1" created="1387369332" modules="C01:P01" cached_until="1387369632">
    ....
  </character>
  <character apikey="key2" created="1387369332" modules="P01" cached_until="1387369632">
    ....
  </character>
</ryzomapi>

Invalid key error:

<character apikey="key1" created="1387369873">
  <error code="404">invalid key</error>
</character>

Possible error codes are listed on API error codes.

PHP interface

ryzom_character_api($apikey)

$apikey can be either string (single key) or array of strings.

On success, function returns associative array of SimpleXMLElement with apikey as array index.

function info($char) {
  if (isset($char->error)) {
    $apikey = htmlspecialchars($char['apikey']);
    $error = htmlspecialchars($char->error);
    $code = (int)$char->error['code'];
    echo "Character API key '{$apikey}' failed: {$code}:{$error}";
  } else {
    $name = htmlspecialchars($char->name);
    echo "Character name: {$name}";
  }
}

$apikey = 'cABCDEF';
$chars = ryzom_character_api($apikey);
if ($chars !== false) {
  info($chars[$apikey]);
} else {
  echo "Character API failed";
}

$apikeys = ['cABCDEF', 'c123456'];
$chars = ryzom_character_api($apikeys);
if ($chars !== false) {

In Game

AppZone

User authentication for apps registered in AppZone

Usage

URL values

user -- base64 encoded php serialized array

checksum -- sha1 hash_hmac with app secret key from AppZone

Because of php serialize, checksum must be validated before user value can be safely used.
A validating checksum will also give a strong guarantee that the user is who he claims to be.

Example how the response is created:

$userArray = [
  'timestamp' => "0.9696200 1503915319",
  'app_url' => 'http://...',
  'id' => "1",
  'char_name' => 'player',
  'race' => 'tryker',
  'cult' => 'neutral',
  'civ' => 'neutral',
  'organization' => 'marauder',
  'guild_id' => '105906000',
  'guild_icon' => '17',
  'guild_name' => 'guild',
  'grade' => 'Leader',
  'lang' => 'en'
];

$user = base64_encode(serialize($userArray));
$checksum = hash_hmac('sha1', $user, $appKey);

timestamp contains microseconds and seconds when the response was created and should be checked to prevent replaying the same response multiple times.
app_url must be checked to prevent same AppZone response to be used in other apps.

PHP interface

ryzom_app_authenticate(&$user)

This function verifies AppZone user and checksum url parameters. Uses $_GET['user'] and $_GET['checksum'] directly.
Function returns boolean true if successful. $user variable will contain info from AppZone or an error message if there was an error

$_SESSION['app.user']

Constants that should be defined :

RYAPI_AUTH_KEY

secret key in AppZone

if empty, then user info is not verified (not recommended)

RYAPI_APP_URL

app url in AppZone

if empty, then automatic best guess url is tried

if false, then app url is not verified

RYAPI_APP_MAXAGE

max age in seconds for AppZone url to be valid

if 0, then timestamp is not verified

<?php
  require_once "ryzomapi_lite.php";

  define('RYAPI_AUTH_KEY', 'secret-key');
  define('RYAPI_APP_URL', 'http://app.url/');
  define('RYAPI_APP_MAXAGE', 30);

  session_start();

  $user = false;
  if (ryzom_app_authenticate($user)) {
    $charName = htmlspecialchars($user['char_name']);
    echo "Hello {$charName}!";
  } else {
    $error = htmlspecialchars($user);
    echo "Authentication failure ({$error}).";
  }
