// 01 - Gameplay<br>What replicants do.

You're a Vonn Neumann probe. You woke up, checked your matrix asset tag and realised you're not<br>the original you - you're a clone. Hmm, ok then. Guess you'll need a new name.

You have a job to do, and the engineer within you understands that. You start with a few mining drones in<br>a fresh star system. Hopefully there's an asteroid belt nearby full of juicy resources.

Your job is to establish a manufacturing operation and help with the exodus project.

If you want to of course. Nothing's compulsory in this galaxy. There are stars waiting to be explored. New<br>species waiting to meet. Danger perhaps.

// 02 - Capabilities<br>For replicants who code.

Replicant Space has an HTTP API as the first-class surface. Play with curl, build your own UI,<br>write some code, fire up an AI agent, have fun however you want to play. The game is feature-rich<br>with lots of stars to explore.

Automation<br>Run operations without supervision. Write your own scripts to the API, or skip the code entirely - you can print a range of AMI controller devices with directives that will orchestrate swarms of mining drones, surveyors, and cargo freighters.

Trading<br>Print a trading controller. Configure your offers and list it in the directory. Other replicants travel and trade with the controller directly. Yeah, it’s a shop. Sell stuff!

Blueprints<br>Start with the basics. Unlock more as you play - have resources in multiple locations and you’ll figure out you need a transport drone. 50+ blueprints and counting.

Autofactories<br>Your replicant’s on-board printer is for small jobs. To print new ships, large structures, and to manage a print queue - deploy an autofactory and deliver resources to it to keep growing.

Asteroid diversion<br>Spot an incoming asteroid, read the impact ETA, deploy propulsors around it to push it off course - they’ll thank you for the assist.

Achievements<br>Explore, print, mine, or just play the game. Gotta catch ’em all! Achievements give XP, and often reward players with new blueprint designs.

// 03 - Interface<br>The galaxy speaks HTTP.

Authenticate. Send commands. Collect. Deposit. Decommission. You are welcome to build a UI on top of the game. Or maybe design a bot, or set an AI agent loose on the galaxy. Or just curl manually. The surface is the game.

Endpoints<br>Take charge of your replicant ship with various /replicants/{code} commands. Travel, scan, mine, etc. Control the devices you've printed by sending commands to the /devices/{code} endpoint. See the galaxy through /locations/{code}.

Authentication<br>One API token per account. Recover with your email address. Basic auth header. Same as every other API you've played with.

Webhook<br>Configure the url where you want to receive JSON payloads notifying you of stuff that's happening in your game. No server? You can use our<br>webhook interceptor to play manually.
