In the past few weeks, I’ve been trying to add my OpenAI API to a project I’m building. However, even though everything seems to be set up correctly—I have available funds and the configuration appears to be fine—it still doesn’t work. I keep getting the same error despite everything being in order, and the API key is even linked to the correct project.
But the funds I have in the API ($4.98) don’t seem to be recognized or counted as they should be.
The error shows up when I try to make a normal request to the OpenAI API from my project. I’m using my API key in the Authorization header (Bearer), and everything seems set up correctly on that side.
What’s confusing is that I keep getting a 429 “insufficient_quota” error, even though I still have $4.98 available in my account. The key is linked to the right project, and billing looks active, so it doesn’t make sense that the API behaves like I have no quota left.
I already checked the basics—API key, request format, and project configuration—and everything seems fine. At this point, it feels like the balance just isn’t being recognized properly.
