Fal.ai api key not working - fal-ai/mmaudio-v2

[ambrish_varshney]

Describe the problem/error/question

I keep getting the Error “Authorization fails” for fal.ai nodes, I tested different api keys and the error persists. I have also tried Fal.ai api key not working this method but no luck. So this much likely might be a problem on fal.ai. PLEASE HALP.

What is the error message (if any)?

Authorization failed - please check your credentials [item 0]

Cannot access application ‘fal-ai/mmaudio-v2’. Authentication is required to access this application

Hey! That error means your fal.ai API key does not have access to the specific model you are trying to use (mmaudio-v2). Some fal.ai models require special access or are in private beta. Log into your fal.ai dashboard and check if that model is available under your account tier, or if you need to request access. If the model is restricted, try using a different publicly available fal.ai model first to confirm your API key works overall.
