07 — Questions

Frequently asked.

How does Obol fetch my usage? +

You connect your provider API keys (admin keys for OpenAI and Anthropic). We call each provider's usage endpoint daily at 06:00 UTC. For Google AI, upload a CSV from Google AI Studio.

Is my API key safe? +

Yes. All keys are encrypted at rest with AES-256-GCM. We never log or display plaintext keys.

Which providers are supported? +

OpenAI (Admin API), Anthropic (Admin API with CSV fallback), Google AI (CSV upload), and OpenRouter.

Can I cancel anytime? +

Yes. Pro is monthly — cancel from Settings at any time.

Why Cloudflare? +

Fast, global, and free to start. We run on Workers + D1 + KV, which lets us keep pricing at $5/mo.
