Buffer API
a free-tier api and an official mcp server, from a company that will still exist next year
a decade-old company shipping a genuinely open api with an official mcp server — the best reliability-per-dollar here, if you can live with the monthly ceiling.
buffer reopened as a real developer platform: self-serve keys from your account settings, bearer auth, and endpoints for channels, posts, ideas and metrics. api access works on the free plan, which almost nothing else here offers.
the rate-limit design is the best in this ranking and it is worth copying. three rolling windows — fifteen minute, twenty-four hour and thirty day — and when you exceed one, the 429 response tells you which window you exhausted and includes a retry-after header. most first-party platform apis just say no.
the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
