Your subscription payments and added funds become a USD balance. AI usage is deducted from this balance at the provider’s exact cost, with no markup.

​
Add funds

Paid subscription invoices add the amount paid to your balance. You can also add $10 to $500 from the billing page using the card on file. Purchased balance does not expire.

​
Track spending

Each request deducts its input, output, and cached usage according to the provider’s pricing. Your balance covers chat, agents, and API usage across supported models.

​
Keep using models

Requests stop when your balance reaches $0. Add funds from the billing page to continue. Use the quota endpoint to check your current balance programmatically.
