Hi @ronakganatra, welcome to WordPress Trac! Thanks for the patch.

The $r parameter is already documented as $args here.

That said, other filters (http_request_args, pre_http_request, http_response) have it documented as $r, so we could probably change it to $r in http_api_debug as well for consistency.

Replying to SergeyBiryukov:
thanx for reviewing.

Docs: Change $args to $r in the DocBlock for http_api_debug filter to match the variable name.

Props bor0, ronakganatra.
Fixes #41379.
