Pricing questions

Do you charge a percentage of my AI spend?

No. Flat price, whatever you spend. Percentage-of-spend pricing is a tax on your growth — we're a tool, not a toll.

What counts as a connection?

One admin key from one provider account. Two Anthropic orgs = two connections. Both connections and discovered keys are unlimited.

What happens if I cancel?

Syncing stops at the end of your billing period. We keep your history, so if you come back it's all still there.

Why does history matter?

Providers forget: OpenRouter serves 30 days, OpenAI's per-key costs about 8 months. Costbase keeps everything from the day you connect — the longer you're connected, the more your dashboard knows that the providers no longer do.
