  Yes, it is possible, I used to do this for simple tasks years ago, before the [Element API](https://plugins.craftcms.com/element-api) plugin was released, and now there is the [GraphQL API](https://craftcms.com/docs/3.x/graphql.html), of course. But it really only is practical for pre-determined queries, otherwise you should probably use one of the solutions above or a custom module/plugin.
  
  Here is a trivial example:
  
  ```
  {# Fetches entries with specific custom field values. #}
  
  {# Get initial entry query. #}
  {% set entryQuery = craft.entries %}
  
  {# Get custom field values from query params. #}
  {% set params = craft.app.request.queryParams %}
  
  {# Filter entries by custom field values. #}
  {% if params.customField1 is defined %}
      {% do entryQuery.customField1(params.customField1) %}
  {% endif %}
  
  {# ... #}
  
  {# Output the entries. #}
  {% set entries = entryQuery.all() %} 
  
  ```
