Description
### Expected Behavior
I was testing the new API nodes today with no issues, whether for images (Flux, SD3.5) or video (Kling, Pika).
I got $2.11 left so I decided to give Luma a try and set it up for the best quality possible: FLF2V, Ray-2, 1080p, 9sec.
(Don't mind the failed outputs in the logs, that's just some harmless 'Save Image' nodes I forgot to bypass)
### Actual Behavior
To my surprise, after 202 seconds, the queue was interrupted and my balance was now $0.00.
The terminal says "Please add credits to your account to use this node" as if "insufficient credits".
I'd totally understand that a 9 seconds 1080p Ray-2 video would cost more than $2.11 but to charge me AND fail BECAUSE OF not enough credits is beyond my comprehension.
Isn't ComfyUI supposed to check my balance BEFORE queueing?
Isn't Luma supposed to reject the generation beforehand?
I ain't blaming the provider here because I'm pretty sure Luma's website wouldn't even let me PROMPT if I didn't have enough credits for said generation. If ComfyUI is building a bridge between user and provider, it means it should manage these potential issues, especially when dealing with money.
### Steps to Reproduce
- Low balance
- Queue "Luma Image to Video" (or maybe any API node? not sure)

### Other
By the way, please build a standard for pricing.
How should I know how many Million pixels would fit in a 9sec 1080p video * 0.0064?
It just looks kinda lazy (different units, fonts, pure copy&paste):
Anyway, I don't mean to get a refund (already got it while writing this! Thanks Yoland, really appreciate it!) but to actually report that there might be something wrong with how Comfy is managing credits and queueing.
And last but not least, I LOVE COMFYUI, it's the best f*cking software I've ever used and I've been using it for so long (March 2023) so don't take it as a personal insult but rather a report/feedback to make it even better.
