Before you purchase
Read the practical terms.
Is pay-as-you-go a subscription?
No. Credit bundles are one-time purchases. There is no recurring plan, automatic monthly charge, or subscription tier on this page.
What does one credit mean?
One AIsentrix credit equals $0.01 USD. Model usage is calculated from the registry rates and the input and output tokens used; some tools have their own displayed per-operation cost.
Do credits expire?
Purchased credits are valid for 12 months. Buying another credit bundle resets the expiry clock on the remaining balance, as described in the terms.
Why can two prompts cost different amounts?
The selected model, prompt length, and response length all affect token-based usage. Image quality or another tool-specific option can also change the displayed operation cost.
Where can I review charges?
The dashboard wallet and analytics views show your balance and recent activity. Pricing is also surfaced in model selection and after supported operations.
