## How costs are calculated

* **LLM services**: Token-based pricing (input/output per million tokens)
* **Pay-per-use APIs**: Per-request cost from the pricing registry
* **Infrastructure**: Monthly plan cost (from your `burn0 init` config)

Pricing data is fetched from the burn0 backend and cached locally for 24 hours.
