One billed request = one successful HTTP response (status 2xx) returned by the API. Failed requests, retries, and timeouts don’t count against your quota.

No. Retries on transient failures (5xx, timeouts, upstream hiccups) are absorbed by us, not billed to you. If we ship you a 200, you pay. If we don’t, you don’t.

Every plan has a hard cap: requests beyond it return 429 until your cycle renews — no overage charges, no surprise bills, ever. Need more mid-month? Upgrade and the new allowance starts immediately with a fresh cycle.

No — the counter resets with your billing cycle: at each renewal, and immediately when you subscribe or change plan. Pick the tier that covers a normal month, and upgrade whenever a bigger one is coming.
