Why prepaid
A billing model made for experiments.
No runaway invoice
StockUp reserves estimated cost before a call, settles actual usage, and pauses when the wallet cannot cover the next request.
Usage in the console
Track request count, token usage, model mix, wallet balance, and API keys from one developer workspace.
Enterprise when needed
Teams that need organization pools, per-user quotas, and governed access can move to Enterprise plans.
Billing FAQ
The details, plainly.
What do I get for free?
A verified developer account receives 100,000 Quan 3.4 L tokens and a separate 100,000-token Quan 3.0 allowance. Free Quan 3.4 L requests can include up to two live searches. The limits are per account, not per key.
Do prepaid packs expire?
No. Developer API wallet funds do not expire, but they belong to the purchasing account and cannot be transferred to another account.
Can I set automatic top-ups?
Not currently. Top-ups are manual, so you control the maximum amount available for paid use.
Why might a request cost more than the visible response?
Provider-reported thinking tokens count as billable output. Deep Research can also include internal stages, and searches beyond an included allowance are metered separately.
Use the free tier first
