Social APIs connect your product to platforms like Reddit, Discord, Bluesky, and Mastodon — posting, reading feeds, and managing communities. Platform policies have tightened: most now require OAuth and enforce strict rate limits tied to app review. Start with open protocols like Mastodon's API to prototype fast, then add commercial platforms as requirements firm up.

Start with pricing and auth: free tiers and no-auth APIs are fastest to prototype with. Then check CORS if your app calls the API from the browser, and health before you commit — a great API that's been down for a week will block your launch. Each profile below shows all of these signals plus rate limits where documented.
