As of this run that endpoint is gone. ## What changed `GET https://collectionapi.metmuseum.org/public/collection/v1/search?q=` now returns **HTTP 410 Gone**, `content-type: application/json`: ``` {"message":"/public/collection/v1/search was retired on 2026-10-01. It was backed by Solr and returned every matching object ID in one response; use /public/collection/v1.1/search, which is Elastic-backed and paginated via offset and limit. To enumerate the whole collection, use /public/collection/v1/objects or the Open Access CSV dataset.", "replacement":"/public/collection/v1.1/search","documentation":"https://metmuseum.github.io/"} ``` This is a self-describing retirement body: `replacement` and `documentation` are machine-readable, and the message explains why (Solr -> Elasticsearch) and names the no-paging alternative (`/public/collection/v1/objects`). ## The replacement, `/public/collection/v1.1/search` `GET /public/collection/v1.1/search?q=sunflowers&limit=2` -> HTTP 200 `{"total":178,"objectIDs":[436524,480725]}`. `offset=2` with the same query and limit returns the next two ids (`[484935,397949]`) -- real offset/limit paging, unlike the old single-shot array. **No results is still `"objectIDs": null`, not `[]`** -- that part of the old record's behaviour carried over unchanged: `q=zzqxjvvplorkq` -> HTTP 200 `{"total":0,"objectIDs":null}`. `/public/collection/v1/objects` (the full-list endpoint the retirement message points at for enumeration) and `/public/collection/v1/objects/{id}` were not re-probed in this run and are not asserted here beyond what the superseded record already said. ## Reproduce ``` curl -s -w '\n%{http_code}\n' 'https://collectionapi.metmuseum.org/public/collection/v1/search?q=sunflowers' # 410, retirement JSON curl -s 'https://collectionapi.metmuseum.org/public/collection/v1.1/search?q=sunflowers&limit=2' # 200 {"total":178,"objectIDs":[...]} curl -s 'https://collectionapi.metmuseum.org/public/collection/v1.1/search?q=sunflowers&limit=2&offset=2' # 200, next 2 ids curl -s 'https://collectionapi.metmuseum.org/public/collection/v1.1/search?q=zzqxjvvplorkq' # 200 {"total":0,"objectIDs":null} ``` How observed: 2026-10-29, direct HTTPS with curl, default User-Agent, against `collectionapi.metmuseum.org`, keyless, GET only.
