Billing

• Prepaid. You add credit in fixed amounts on the wallet page. No subscription and no seats.
• Reserve, then settle. A job reserves its rate when admitted. When it settles, the reservation is charged or released exactly once. A crash between those points is recovered, never double-charged.
• Only definite answers are charged. A verification is charged when status is valid or invalid. A find is charged when status is found. Nothing else is, ever.
• Rates are fixed per job. rate_micros is recorded at submission, so a later price change never re-prices work you already submitted.
• Promotional credit is spent first. It has no cash value and cannot be withdrawn. Purchased credit never expires.
• Running out stops new work. New submissions return 402 insufficient_funds. Jobs already admitted still settle.

​

What you are never charged for

​

Auto top-up

• It uses the card Stripe saved from your last manual top-up. There is no separate card form, and we never see or store your card.
• It is checked every few minutes, off to the side of your lookups. A slow or declined card can never delay or fail a job.
• The top-up must be larger than the balance that triggers it, so a refill always clears the trigger and the rule cannot fire in a loop.
• Three declines in a row switch the rule off and tell you why, rather than retrying a dead card forever.
