Do I need to manage API keys?

Use OpenAdapter directly in browser-based apps

Browser-based, OpenAI-compatible apps — like Janitor AI, SillyTavern, and other web chat front-ends — can now call the API directly.

Set the endpoint to https://api.openadapter.in/v1/chat/completions and use your sk-cv-… key.
Previously these apps hit a browser "network error" because the API only accepted requests from our own domains. The /v1/* endpoints now accept any origin.

Note: only paste your key into apps you trust — a key used in the browser is visible to that app.
