## FAQ

### Do I need an API key for embeddings?

No, JitAPI uses local embeddings out of the box, so no API keys are required for basic functionality.

### How does JitAPI handle large API specifications?

Instead of loading the entire spec into context, it uses semantic search and a dependency graph to surface only the necessary endpoints.

### Can I use multiple APIs at once?

Yes, you can register multiple APIs and ask questions that span across them, allowing Claude to chain calls between different services.

### What authentication methods are supported?

It supports bearer tokens, custom API key headers, and API key query parameters.
