Query Posts without URL parameters to avoid running into character limit with many filters

[anghenfil]

Hey,

currently, the REST API only supports GET requests to query posts. This is fine as long as the query including all filters (e.g. category filters) don't exceed the 2048 char URL character limit. Some servers will report an 500 Internal Server Error if exceeding the limit.

This is problematic, especially when using the exclude category filter which can't be replaced by multiple smaller requests.

There should be an API route to filter posts by body parameters.
