Provider Status

No key saved

Provider Configuration

Save an endpoint and key here to pre-fill the validator. Any provider speaking the Anthropic /v1/messagesshape works, whoever's models it resells. Your key stays in this browser's local storage (lightly obfuscated, not encrypted) and is never sent anywhere except the provider you configure.

Saved Key

A saved key pre-fills the validator on the main page. Removing it only clears this browser's storage — nothing else on your machine is touched.

No key saved
