Every API here publishes an OpenAPI specification at a public URL. We check it on a schedule — no scraping, no guesswork.
New endpoints, removed parameters, changed schemas — the diff engine records exactly what moved between versions.
Each change is classified as breaking, potentially breaking, or safe — so you know at a glance whether to care.
Missing an API you depend on? Tell us which one and we'll add it to the directory. The more requests an API gets, the sooner it lands.
Each vendor publishes an official OpenAPI (or Swagger) specification at a public URL. We fetch it on a schedule, diff it against the previous snapshot, and record every meaningful change. Nothing is hand-written — if it's in the changelog, it changed in the spec.
Removed endpoints, removed or newly-required parameters, narrowed response schemas, changed types — anything that can make an existing client fail. Changes that only add functionality are classified as non-breaking.
Yes — open any API's changelog page and add your email. We'll watch the spec for you and email you when it changes. You can also watch any other spec URL from the validator.
If your OpenAPI spec is at a public URL you can watch it yourself for free — and with the GitHub Action you can validate and diff it on every pull request. Want your API listed in this directory? Request it here — it takes a few seconds.
