Datasets
AutoSugges's reference data catalog — real provenance, a real licence and a worked example for every dataset, whether it's free today or still an offering.
AutoSugges-published free datasets are never priced on their own — every plan includes all of them. What a plan prices is how many queries you may make, not which free list you may query. A few catalog entries are licensed from a third party or supplied by you, and those carry their own access terms, shown on that dataset's own page.
