Plans, limits and billing
Successful requests and their tokens (prompt + completion, as reported by your provider) count toward the monthly limits. Failed requests don't count. At the limit, the gateway answers HTTP 402 with code plan_request_limit or plan_token_limit until the 1st (UTC) or an upgrade. We email owners at 80%. You're never charged overage, and provider costs are billed by your provider.
Cancel any time from Billing; you keep the paid plan until the period ends.
