How to setup Fal AI api in N8N

Questions people ask

What does fal.ai do?

It hosts AI models behind an API and bills per run. You send a request naming a model, it queues the job on a GPU and returns the output. You are renting inference, not a product.

Can I use fal.ai for free?

There is a small starting balance to test with; sustained use is paid per second of GPU time. Anything generating video is where that adds up fastest.

Do I have to pay for fal.ai?

For anything beyond testing, yes. Pricing is per model and per second, so two models that look similar can differ by an order of magnitude on the same job.

How do I start using an AI API as a beginner?

Get a key, run one request with the provider's own example, then change one field at a time. The mistake that costs people a day is starting from a large workflow instead of from one working call.

Should I call fal.ai directly or through one API?

Directly is fine for one model. Once you use several, one endpoint in front of them saves you a separate key, billing account and error format per vendor.
