🚀 Getting Started with APS's LLMS.TXT and Cursor IDE

Welcome! This is the repo for the APS llms.txt file(s).
It is also a short guide for developers, citizen developers, and domain experts who want to vibe code Autodesk Platform Services (APS) APIs using the AI-powered Cursor IDE. With just a few steps, you’ll be setup to generate and test real API code using plain-English prompts—powered by APS + CursorAI + llms.txt.

🧠 What’s “Vibe Coding”?

Vibe coding is the new way of working in AI-assisted IDEs. You don’t start with a blank file. You talk to your editor, describe what you want, and let it scaffold, correct, and enhance your code. It's part code generation, part pair programming, and 100% about speed, flow, and creativity.

💡 New to Cursor or vibe coding? Don’t worry if this feels unfamiliar—part of the magic is letting the AI help you work through it. Think of Cursor as your coding partner. Start by describing what you want, and let it guide you. You’ll be surprised how far you can get with just a good prompt. .

🎥 3-Step Intro: Watch & Learn

Each step includes a short video (30 seconds) to help you follow along.

▶️ Step 1: Add LLMS.TXT to CursorAI

• Open Cursor IDE
• Go to 'Settings' -> Indexing & Docs and click Add Doc
• Type in https://aps.autodesk.com/llms-full.txt and add the name Autodesk APS APIs and click Confirm

▶️ Step 2: Test It Out

• Point Cursor AI to our Autodesk APS APIs using the @Docs feature
• Select 'Ask'
• Now try asking:
  “Can you see the APS docs? what is SSA ?”

▶️ Step 3: Build a "List Hubs" Example (Python)

• Use prompt-driven coding to "list all my hubs from a simple command line tool" - using Python.
• Switch to Agent mode.
• Now try asking: “create a python script that uses ssa, gets an access token using ssa rest apis and uses an example.env file containing aps key/secret, private key, scope, etc and lists the acc hubs. ignore error checking and no comments.”

The end result ? I run the command python3 list_hubs.py and it shows the hubs my robot (SSA) has access to using 3LO access tokens.

ps. Here is my `example.env' file I used in the video. I asked Cursor to use these variable names, instead of the ones it initially suggested:

APS_CLIENT_ID=XLA....................................0ep3i
APS_CLIENT_SECRET=RCB...................................................84e
SERVICE_ACCOUNT_ID=VR2........V5
KEY_ID=288........8322d
APS_SCOPE="data:read data:write"
APS_PRIVATE_KEY="--- ....................... 6FsPjyf\n-----END RSA PRIVATE KEY-----"

▶️ Step 4: Vibe Code - View a Revit model in a browser. (Python)

• Use prompt-driven coding to build a command line tool, that let's you upload and view a Revit model in a browser using APS. We'll use python to do the file upload, Model Derivative API to convert RVT to SVF2, and use the Viewer SDK inside our custom webpage. Let's call it upload-and-view.py example.
• Switch to Agent mode
• Try asking: “create a python cli tool script, use APS rest calls and ignore error checking and comments. create an 'upload' command and a 'host' command. first, Upload a .rvt (or .nwd, .dwg, etc) file to APS (a bucket) using APS key/secret from a .env file (APS_CLIENT_ID, APS_CLIENT_SECRET, APS_BUCKET_DEFAULT), next convert it to SVF2 using model derivative API and return the URN and access token. Second command, host a viewer.html webpage, where a browser will use viewer sdk to load that URN and pull a fresh 2legged (2LO) access token from this host server.”
