Choosing between these Business & Commerce APIs
Business APIs cover company registries, job boards, product catalogues and commerce infrastructure. Official company registries in several countries are open data and unusually reliable.
Job board and e-commerce APIs tend to be the most restrictive on free tiers, since the data is the product. Check whether redistribution is permitted before building anything public-facing.

These are catalogued from the public-API lists and link straight to each provider's own documentation — we have not tested them yet, so treat the auth and CORS flags as the upstream list's claim rather than ours. They are promoted to a full tested page as we work through them.
