How to list AE output module presets and render a comp via command line (AE 2025+) without opening A

I’m working on an automation app called X-Cast (built in Electron/NodeJS). The app patches an .aepx project file with correct data and then needs to render a specific comp from that project.

I know I can trigger renders using aerender.exe, but I have two main challenges:

1. Populate AE Output Modules in UI
   I need to programmatically load After Effects’ output module presets (codecs and settings, e.g., H.264, ProRes, etc.) into my app’s UI so users can select their desired codec. Is there a way in AE 2025+ to query or export this list without launching the AE GUI?

2. Render without opening AE UI
   After the user selects a codec, I want to start rendering from the command line — ideally using aerender or another supported headless method — so the AE GUI never launches.

Questions:

• How can I fetch the available AE output module presets programmatically (2025+)?
• What’s the best supported way to trigger rendering of a specific comp from an .aepx via command line, fully headless?
• Is there any modern API or workflow (beyond aerender) recommended for this?

Environment:

• Windows 11
• After Effects 2025
• External Electron/NodeJS app (X-Cast)

Thanks in advance for any guidance or examples!
