​
Authentication

All LeoKit endpoints use an API key passed in the Api-Key header.
​
Api-Key
string
required
Your LeoKit API key.
Never commit API keys to version control or embed them directly in documentation pages.

​
Use the API Playground

1

Add your API key once

In any endpoint page, open the API Playground and paste your API key into the Api-Key field.
Mintlify stores this value in your browser, so it will be reused across all endpoints.

​
Demo key (sandbox)

Use your demo key in the API Playground:

If you want the docs to be “ready to run” for every visitor, treat the demo key as public (tight rate limits, sandbox-only, minimal permissions). Even then, it can be abused, so you should expect to rotate it.
