The Decisions API bills per token read, by model: $0.025 to $0.035 per million billed tokens, at least 256 tokens a request. There is no subscription and no seat count. Every account starts with $5 of free credit, no card needed: 200 million billed tokens on opendecision-large-packed. See what is billed. Training a fine tune has its own price, and only a win is charged.

​
Prepaid credits

Buy credit up front in the dashboard under Billing; each request draws down the balance. At a zero balance POST /v1/decide returns 402:
Nothing else changes — keys stay valid, and requests succeed again the moment credit lands. An account can never spend more than it holds. Credits do not expire.

​
Low-balance alerts

Set the dollar balances you want to hear about — $5, $1 and empty by default — in the dashboard under Settings. Crossing one emails the organization’s owners and admins, or a single address if the org sets one there. Members are not emailed: they cannot buy credit, so the alert would be noise about a problem they cannot fix. Alerts warn. They do not stop anything: at a zero balance the credit gate itself is what refuses the request. A new top-up resets the mark, so the same account can warn again the next time its balance runs low.

​
Handling 402 in an agent

Retrying a 402 will not succeed until credit is added.

​
Fine tunes

A fine tune with a file costs $2.00, charged only if it beats OpenDecision-Small on rows labeled by you. A job with no file is never charged. A job that fails, is canceled, or does not win costs nothing. Starting any fine tune needs $2.00 in your balance. A job with a file holds $2.00 until it ends, and the hold then becomes the charge or goes back to your balance. A hold counts as spent while it lasts, so a low balance can get a 402 on /decide, or a low-balance email, until the hold ends. Billing lists each hold and charge. Hosted calls to a fine tune bill at the opendecision-small price. Running one on your machine and downloading it are free. See prices and limits.

​
Payments and invoices

Payments are processed by Stripe and sold through Link, our merchant of record. Link handles cards, currency and sales tax, sends the receipt and invoice, and appears on your statement as LINK.COM*. We store no card details. tokz keeps the credit ledger and the usage counters behind it; the payment instrument never reaches our servers.

​
What we count

Billed tokens of the text and questions you send, priced by model, and any fine tune that won. Answers are free, and requests that fail (any 4xx or 5xx) are not billed.
