Helldivers2API-NET

Another open source library for the undocumented Helldivers2 API.

🌟 This project reads directly from Helldivers 2 api 🌟

Features

• .NET 7
• Easy to use
• Built-in cache system
• Consolidates various planet data under a single source
• Leverages the game's api directly, e.g. does not use an intermediary api that may stop working
• Helps spread managed democracy

Planets, Planets, Planets

The majority of data from the Helldivers2 API is associated to one or more planets. Because of this, we have made most data retrievable directly from the IPlanet object. There's no need to jump through multiple requests and pair the data together, this project has done this internally.

Overview

All information is retrievable through the convenient Joel class.

• Initializes itself to the current war id added in version 1.1.4
• Get statistics added in version 1.1.3
• Get current assignments, e.g. the Major Order
• Get news from the galaxy
• Get status of the on-going war efforts
• Get information of the on-going war
• Get all the known planets in the galaxy, including their
  • Sector
  • Biome
  • Envrionmental conditions (fire storms, etc)
  • Supply lines to other planets
  • Player count
  • Health / MaxHealth
  • Planets in conflict
  • Original owning faction
  • Current owning faction
  • Factions that claim it as a home world
  • Regen rates
  • Active campaigns
  • Associated planet events
  • Associated global events
  • Associated joint operations
  • etc

Installation

Install the NuGet package via the package manager NuGet\Install-Package Helldivers2API or .NET CLI dotnet add package Helldivers2API

Getting Started

Get the client by setting the current war id, via Joel

// Sets the current war id, as of 1.1.4
var hdClient = Helldivers2API.Joel.Instance;

// No longer needed, unless you want to override war id
// var hdClient = Helldivers2API.Joel.Instance.SetWarId(801);

Get all the known planets

var planets = hdClient.GetPlanets();
foreach (var planet in planets)
    Debug.Print($"Planet {planet.Name} resides in the {planet.SectorName} sector");

Get all the assignments

var assignments = hdClient.GetAssignments();
foreach (var assignment in assignments)
    Debug.Print($"Assignment: {assignment.Brief}");

Get all the news

var newsfeeds = hdClient.GetLatestNews();
foreach (var newsfeed in newsfeeds)
    Debug.Print($"{newsfeed.Message}");

Note

The information from the WarStatus and WarInfo that relates to a Planet is retrievable from the Planet object directly.

Get the status of the on-going war efforts

var warstatus = hdClient.GetWarStatus();  

Get information about the war

var warinfo = hdClient.GetWarInfo();     

Cache System

The built-in cache system was designed to avoid sending unnecessary requests to the web api endpoints. It's entirely internal and you do not need to manage it. Just request the data and it will handle the rest.

The default cache expiration, per endpoint, is about 5 minutes, although this may change in the future.

Tip

The web api is never hit until the first request for data is made, at which point only the necessary endpoints are requested.

static void HDClient()
{
    // Sets the current war id, as of 1.1.4
    var hdClient = Helldivers2API.Joel.Instance;

    var planets = hdClient.GetPlanets();
    foreach (var planet in planets)
        Debug.Print($"Planet {planet.Name} resides in the {planet.SectorName} sector");

    var assignments = hdClient.GetAssignments();
    foreach (var assignment in assignments)
        Debug.Print($"Assignment: {assignment.Brief}");

    // this call will return data from the local cache since it was just requested (web api endpoint is not hit again)
    var assignments2 = hdClient.GetAssignments();

    // var newsfeeds = hdClient.GetLatestNews();
    // foreach (var newsfeed in newsfeeds)
    //     Debug.Print($"{newsfeed.Message}");

    // omitted for cache example
    //var warstatus  = hdClient.GetWarStatus();

    // omitted for cache example
    //var warinfo = hdClient.GetWarInfo();

    var lastRef = hdClient.GetLastRefreshed();
    foreach (var lastRefreshed in lastRef)
        Debug.Print($"{lastRefreshed.Key} was last refreshed {lastRefreshed.Value}");
}

// Assignments was last refreshed 3/24/2024 12:25:25 PM
// WarInfo was last refreshed    <-- date is null because it was never called, thus a request was never sent to the web api endpoint
// WarStatus was last refreshed  <-- date is null because it was never called, thus a request was never sent to the web api endpoint
// NewsFeed was last refreshed   <-- date is null because it was never called, thus a request was never sent to the web api endpoint

Incomplete Data Models

Warning

There are still a handful of type attributes from the Helldivers2 API that have not been researched. They will return the raw value from the api (typically int) for now.

Warning

Data structures that have not been observed from the Helldivers2 API may be omitted until they return a structure we can map safely (capitalInfos, activeElectionPolicyEffects, etc).

Thanks to all the various communities and sources out there that have documented and shared information about the Helldivers2 API.
