A top-up of $60.00 covers this. Credit stays valid for 12 months.
How credit works
- Top up from $10. Pay by card through Stripe: $10, $25, $50, $100 or any whole-dollar amount from $10 to $1,000 per top-up.
- Valid for 12 months. Each top-up expires 12 months after you add it. The oldest credit is used first.
- Charged on success. Failed jobs cost nothing, and so do jobs you cancel while they are queued.
- Per second, 1-minute minimum. A 3 m 12 s file is 192 s = $0.1056. A 20 s file is billed as 60 s = $0.0330.
- Test keys are free. zil_test_ keys return a fixed sample file. There is no free trial of live jobs.
- Refunds within 14 days. Unused credit from a top-up can be refunded within 14 days of that top-up.
Questions
What happens when my balance runs out?
New jobs are rejected with 402 insufficient_credit before they start. Jobs already accepted always finish, because their cost was held when they were created. We never charge your card unless you start a top-up.
How is the duration measured?
From the decoded audio, not the file size. Billable seconds are the duration rounded up to the next whole second, with a 60 s minimum per file.
Can I get a receipt?
Stripe emails a receipt for every top-up, and every job records what it cost and why.
Do prices change?
Each job records the unit price and pricing version it was created with, and is charged at that price. A price change never affects a job you already started.
