How does the rolling request window work?
Each plan includes a trailing 5-hour request allowance that refills continuously as older requests age out — there is no daily reset or monthly credit balance to track.
What happens when I exceed my window?
If you opt into wallet spillover, requests past your rolling window (plus above-tier models, long context, and embedding overages) are debited from your wallet at published catalog rates. Otherwise they queue until the window refills. Wallet top-ups never expire.
How is inference cost calculated?
Flat-rate plans cover usage within your rolling window. Anything billed to your wallet uses the per-model token, page, and endpoint rates listed in the tables above. Failed requests are not charged where metering supports it.
Can I change plans?
Yes. Upgrade or downgrade through billing settings in your account. Changes typically take effect on the next cycle per Stripe rules.
What is the concurrent request limit?
It caps how many API requests can run in parallel per key. Higher tiers allow more throughput for bursty workloads.
