Pricing
$0.0075 per minute of audio, for both models. Speech to text is $0.00015 per minute of recording ($0.009 an hour). You're charged for the length of the audio you receive, to the millionth of a dollar, so a 10-second clip costs $0.00125. There are no plans, seats or minimums.
- Requests that fail on our side cost nothing.
- If you disconnect partway through a stream, you pay only for the audio that was sent.
- Each realtime piece is billed the same way, as its own request.
Credits
Usage draws down a prepaid balance in US dollars.
- Top up in the console under Billing: $5 to $5,000 at a time, by card, with a receipt for each.
- Auto-recharge tops you up when the balance falls below an amount you choose, using your saved card, so your app never stops.
- At zero, requests fail with
402 insufficient_creditsuntil you add credit. Requests already running finish.
The console shows your balance, every top-up, and your usage and spend by day. Receipts, invoices, your card and your billing details (address, tax ID) are in the billing portal, linked from the Billing page.
High volume or invoicing? We offer custom rates and monthly invoicing with payment terms. Email business@iodine.dev.
Zero Data Retention
Zero Data Retention (ZDR) is on for every account by default, at no extra cost:
- The text you send is held in memory only while the audio is generated, then discarded.
- Generated audio is streamed to you and never stored. Responses are marked
no-store. - We keep only request metadata (when, which key, model and voice, the character count but not the characters, audio length, time to first byte and status), which powers your usage page and billing.
The account owner can turn ZDR off in the console's settings. While it's off, we keep the text and audio of each completed request and may use them to train and improve our models, and those requests cost 15% less: $0.006375 per minute at the list price. Turning it back on takes effect immediately for new requests, and the owner can delete everything kept from the console. Cloned voices are never used for training, whatever the setting.
