Choosing between these Social Media APIs
Major social platforms have steadily restricted their APIs, so most now require OAuth, app review, or a paid tier. The genuinely open options tend to be smaller or federated platforms such as Mastodon and Lemmy.
Link preview and Open Graph APIs are the practical standouts here — they need no platform relationship and solve a real problem when rendering shared URLs.

61 further APIs in this category, of which 9 need no API key. 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.
