Per-user AI credits, without the plumbing
Give every user their own credit balance. Set your margin, earn on every request. One API for OpenAI, Anthropic, and Google.
Ship AI credits in three steps
Integrate once, monetize any AI model. No custom billing code, no balance tables to maintain.
Get your API key
Create a free account and generate an API key. You get a starting balance to test with immediately.
Point your SDK at Quota
Change your OpenAI base URL to Quota. Your existing code works — same SDK, same format, same models.
Give users their own balance
Add the user header to requests. Each user gets a credit balance, topped up via Stripe checkout. You earn your margin automatically.
Everything you need to monetize AI
Add per-user credits to your app. Quota handles balances, billing, and multi-provider routing so you can focus on your product.
Per-user credit balances
Every user gets their own balance. Credits are deducted automatically on each AI request. Users never go negative — requests are blocked before they overspend.
Earn on every request
Set a profit margin on your app. Users pay the base model cost plus your markup. You keep 100% of the margin — no platform fee.
One API, three providers
Route to OpenAI, Anthropic, or Google through a single endpoint. Same OpenAI SDK format — change your base URL and you are done.
Credits work across apps
Users carry their Quota balance between apps. More apps on Quota means more users who already have credits ready to spend in yours.
One line to get started
Quota works with the OpenAI SDK you already use. Change the base URL, and every request is automatically billed to the user.
