I already have the basic plan, but if I go beyond 5 dollars, I would like to know if there is any way to buy credit, without the intention of buying a higher plan, as I am still just learning.

I went to look at my railway usability panel and saw that it increased from 5.06 to 7.02, but during this period I was with my father at the hospital, as I am a beginner I would like to know what is happening, and if it is in the configuration only charge when I am running it

and also, it is not active for the public

I understand what you said, but I don't understand what's going on, because I have 5% of the project being tested, which is just a chat to answer questions with AI n8n, about tarder, with only 16 pdfs, and it costs 14.99 per month. I use mini openai, it doesn't make sense, and that's what I would like you to help me know if it's the platform's value, if it's my codes that are generating, I want help, because with this value I'm going to have to stop a project that I've barely started.

and if you have to stop the project from charging when you are not using it in its development, is there any way?

How do I stop it when I'm not using it, since I'm still developing the project?
Do you have any idea of ​​what might be happening, since my project is small, an AI that consults a Google Drive folder and answers questions related to it, and an API, to consult the assets (trader) in the analyses
and it's on the invoice (image not sent) for 14.99 dollars, it's a lot, imagine if it had scalability, it would be impossible to put it on the market

What I don't understand is that I don't have access to n8n, with bills worth 9.99 dollars and now I see that it's worth 10.37.
If I don't have access, is the amount to be fixed at 9.99 or is there a link I can use to stop paying until the next bill opens, so I can use railway (that was the question I asked in the other question and I didn't get the answer)

but that's what I want to know from the beginning, where do I restore, you can see I even asked what link could do this?
