Firebase pricing plan requirements for your chosen API provider
The Gemini Developer API offers different tiers for its pricing:
Gemini Developer API "free tier": This tier requires that your project is not linked to a Cloud Billing account. This means your Firebase project is on the no-cost Spark pricing plan.
Gemini Developer API "paid tiers": These tiers require that your project is linked to a Cloud Billing account. This means your Firebase project is on the pay-as-you-go Blaze pricing plan.
