# API Explorer control

> Enable or disable the API Explorer for OpenRPC methods using `x-fern-explorer`

The [API Explorer](/learn/docs/api-references/api-explorer) is enabled by default for every method. Set `x-fern-explorer: false` at the document root to hide the Playground for all methods, and override it on individual methods; a method's own value takes precedence. Non-boolean values are reported as errors when importing the specification.

**`openrpc.yml`**
