SpaceTraders is an open-universe space-themed game that offers a set of HTTP endpoints to control a fleet of ships. All players operate their fleet in the same universe, and the game is currently in alpha.

The API is fully documented using OpenAPI and Stoplight Studio. You can send your first request right here in your browser to check the status of the game server, or try our Quickstart Guide to learn the basics in under five minutes.

curl 'https://api.spacetraders.io/v2/'

Unlike a traditional game, SpaceTraders is headless and does not have a first-party client to play the game.

Instead, you as the player are responsible for building your own client to interact with the API. This allows you to build your own UI, automate your trade routes, or just play the game from the comfort of your terminal.

We have a Discord channel where you can share your projects, ask questions, or give feedback on what others are building.


SpaceTraders is a space-themed universe where you can explore star systems, trade goods, mine asteroids, and take on faction contracts to earn credits and reputation.

Ships are the primary vehicle for interacting with the game world. You can buy and sell ships, navigate them between waypoints, upgrade them with new mounts, and send them on trade routes to earn credits.

The economy of the game is simulated and significantly influenced by player actions. Prices of goods fluctuate based on supply and demand, and players can influence the market by buying and selling goods in different systems.

All players operate in the same universe, so you can compete with others to earn the most credits or chart the most systems.

To learn more about the game, check out our gameplay concepts guide, or try the quickstart to start a new game and test various API endpoints from your browser.

The game is currently in alpha and under active development, so we are always adding new features and content.


We are a small self-funded team dedicated to keeping the SpaceTraders platform alive and accessible for everyone, and free for as long as we can support it.

You can donate to the project using the link below. Contributions will go directly towards maintaining server costs for the community. As we fund everything out of pocket, every donation, no matter the size, makes a big difference.

We’re grateful for your support and excited to see what you build with the SpaceTraders API!

Next steps

The SpaceTraders API is an excellent platform to learn a new programming language, test a new framework, or stretch your skills in a fun and meaningful way.

If you are new to SpaceTraders, you should try our interactive quickstart guide which will walk you through basic API requests in just a few minutes.

If you're looking for some project inspiration, here are some ideas to get you started:

  • create a script to mine asteroids and automate trade routes
  • build a web or mobile app to manage your fleet of ships
  • track and share market price data with other players
  • generate an SDK from the OpenAPI spec and publish it
  • create a Discord bot for others players to use
