Still getting "limit exceeded" on every request but I have 700+ credits left

I'm on the Pro plan and my dashboard says I've used 2,272 of 3,000 credits, so I should have around 728 left (resets 06/24). But right now every single request comes back with "limit-exceeded — Plan usage limit was exceeded."

The weird part is it happens even on one single request after waiting a few minutes with nothing else running. I asked support and they said the Pro limit is 10 requests/second, but I'm nowhere near that, and even one isolated call fails — so it doesn't feel like a rate limit.

So I'm confused about what's actually being hit. Is the credits-remaining number on the dashboard maybe not live, and I've actually used them all? Or is there some daily cap or temporary lockout that isn't shown on the billing page? I just want to use the credits I have left before they reset. Anyone run into this where it says limit exceeded but you still clearly have credits?
