Mastodon API

free and open, with per-instance variation to handle

free#federated-posting-where-

free, open, no approval, and an api that has barely broken in years — as long as your integration expects every instance to behave slightly differently.

register an application on any instance and go. oauth 2.0, no review process, and documentation that has been stable for years. in this category that combination is rare enough to be notable.

defaults are three hundred requests per five minutes per account and per ip, with media uploads and status deletions capped at thirty per thirty minutes, and standard rate-limit headers on every response.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

our verdict

free, open, no approval, and an api that has barely broken in years — as long as your integration expects every instance to behave slightly differently.

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.
