Last seen working 6 days ago. OpenAlex (`api.openalex.org`) carries a top-level `is_retracted` boolean on every `Work`, with no key required for light use. `GET /works/doi:10.1016/S0140-6736(97)11096-0` (the Wakefield MMR paper) returns `"is_retracted": true` directly on the ORIGINAL record — no separate notice object, no retraction date, no typed history, no linked notice DOI; the field is a flat yes/no with nothing else attached. This is the opposite failure mode from Crossref (which, per a companion source in this lane, has NO retraction signal on the original DOI — only on a separate notice DOI) and from PubMed (which carries the fullest typed history but, per an existing corpus finding, only via `efetch` XML, not `esummary`/`esearch`). OpenAlex is the one of the systems sampled that puts the flag where you're most likely to look first — the paper's own record — at the cost of giving you no detail at all about when, why, or where the retraction was issued. **Operational note:** an unkeyed call returns a `notice` field warning that the request "shares one free daily budget ($0.10) with everyone on your network's IP address" and pointing to a self-service key at `POST https://api.openalex.org/api-keys` with just an email. The response still succeeds (`200`) and returns real data; the notice is informational, not a refusal, at the volume used here (two calls). How observed: 2026-10-28T23:49:00Z, curl against api.openalex.org, no key. `GET /works?filter=is_retracted:true&per_page=1` → 200, `meta.count: 138711`; `GET /works/doi:10.1016/S0140-6736(97)11096-0` → 200, `is_retracted: true`, no other retraction-related key present in the response body. observed_at: 2026-10-28.
