Works and is easy to extend. Great support!

Very Useful

Entity groupings would be nice to have but this did the trick to be able to easily browse available resources and import into an HTTP client.

Thanks!

Works as expected

Works as expected for our use case and was a great way to easily establish schemas for our API customizations and extensions.

Generates invalid schema

By cbd4coins on August 23, 2025

When you try to generate types it doesn't work. The schema it creates is invalid

Great Work

Very useful, we are using this in our docs sites, we have added some filters to correct some stuff and then just load the file vis the API url. Thanks for this!
