Frequently Asked Questions
How does auto-pause work?
When a prompt template's cumulative spend reaches your configured limit, Budget Guardian sends a pause signal via webhook to your API layer, halting further calls until you reset or raise the limit.
Which AI providers are supported?
Any provider that exposes usage data via API or webhook — including OpenAI, Anthropic, Cohere, and others. You pipe usage events to our endpoint and we handle the rest.
Can I change or cancel my plan?
Yes. Your subscription is managed through Lemon Squeezy. You can upgrade, downgrade, or cancel at any time from the billing portal with no penalties.
