Filter any RSS or Atom feed using regex. Subscribe to only what you want.
Build a URL with query parameters:
GET /feed?url=FEED_URL&filter=REGEX&field=FIELD&mode=MODE
Multiple filters can be applied (AND logic) by repeating the filter, field, and mode parameters.
Use GET /fields to see all available field names.
