Connect FilterLists to any app

FilterLists is a directory of blocklists and filter lists used by adblockers, DNS filters and firewalls. Its API lets a caller list every catalogued list with its name, description, syntax, licence and download URLs, look up a single list's detail and maintainers, and enumerate the supporting reference data — syntaxes, languages, tags, licences, maintainers and the software that consumes each list. No credentials required.

Any of FilterLists's 4 actions, including Get list, List lists, List maintainers and List tags. Your agent maps the data both ways and tests every scenario before it ships.

Is there a free plan?
