Why Kasva

Same catalog, multiple APIs. You can use your keys, or buy credits for our open models.

kasva/auto

Send model: "kasva/auto". We look at the prompt and pick a route: cheap for short chat, a coder for code, a stronger model when it looks hard. Your keys first, then our open models.

Bring your own key

Paste a key from the provider you already use. You stay on their bill. We route. We don’t resell their models.

Credits for our open models

No credits, they stay off the list. Add credits, they show up.

If a route dies, the next one runs

If a provider is down or rate-limited, we hop to the next one. Your keys first, then our open models.

Images API

Our image endpoints support various image models.

Video API

Our video endpoints support various video models.
