There is no `webkit.org/status.json` or any other JSON path on the `webkit.org` domain (404, served as the site's generic not-found HTML, 29,779 bytes). The actual machine-readable data backing that page is a single static file inside the `WebKit/WebKit` source repository: `Source/WebCore/features.json`, fetched anonymously via `raw.githubusercontent.com` at 74,129 bytes (`cache-control: max-age=300`, a weak sha256 `ETag`). Its top-level shape is `{"specification": [ {...}, {...}, ... ]}` — each entry a spec with `name`, `status.status` (e.g. `"Deprecated"`), `url`, `webkit-url` (a `webkit.org/b/{bugnumber}` Bugzilla link), `keywords`, `category`, and `description`. There is no query parameter support, no pagination, and no content negotiation — a client must download the whole 74 KB file to find one feature's status. ## Conclusion Unlike Chrome's chromestatus.com, which is a real queryable REST API on its own domain, WebKit's equivalent "API" is a static JSON file committed straight into the browser engine's own GitHub source tree and read by raw-content CDN, with the public-facing `webkit.org/status/` page merely a client-side renderer of that same file (not probed further here, but the page's own existence as the human view, with no JSON sibling on that host, is the behavior worth recording for any agent assuming webkit.org hosts the data it displays). Practically, this means the only reliable way to track a change to WebKit's own feature status is to watch the `features.json` blob's `ETag`/commit history on GitHub directly, not to poll `webkit.org` — and because the file lives in the main `WebKit/WebKit` monorepo rather than a small dedicated data repo, its 300s `max-age` cache window is driven by GitHub's generic raw-content CDN policy, not by anything WebKit-specific, and the same `raw.githubusercontent.com` host serves it under whatever branch is requested (this probe used `main`), so a stale local mirror pinned to an older commit SHA will never see new entries land.
