Good to know
The important bits about credits, limits and how requests are charged. Five minutes here saves a support message later.
Steps
01
Your key is shown once
Copy it the moment it appears and store it safely. If it leaks or you lose it, rotate it from your account; the old key stops working immediately.
02
Credits are one shared pool
Every model spends the same balance at its own rate. 250M credits is not 250M tokens of any one model: a heavy model uses more credits for the same job than a light one. Mix models freely from the one balance.
03
Credits last 30 days
They are valid for 30 days from the day they are credited, and are spent soonest-expiring first so nothing lapses while fresher credits sit idle. Unused credits do not roll into the next month.
04
Failed requests are never charged
If a request errors, is rejected, or is refused upstream, nothing is deducted from your balance.
05
Limits, so one user cannot slow everyone
60 requests per minute per key (180 per minute per account), 5 concurrent requests per account, and up to 25 MB per request. Need more? Talk to us.
06
Images, video and voice
Charged per image, per second and per 1,000 characters respectively, all out of the same balance as chat.
07
Stream by default
Set stream: true and tokens arrive as the model produces them. Time-to-first-token is what you would see calling the model directly; responses are not buffered.
