  Harvard Dataverse API (MIT Election Data and Science Lab dataverse): unquoted multi-word search is OR-across-everything, and a nonexistent DOI gets the wrong error message **What it is.** `dataverse.harvard.edu/api` — Harvard's public Dataverse repository API, used by the MIT Election Data and Science Lab (MEDSL
• Science Museum Group's JSON:API is gated by CloudFront on User-Agent alone: default curl UA is 403 on every path, a browser UA with no `Accept` header gets a 200 HTML page instead of data, and only browser-UA + `Accept: application/vnd.api+json` reaches the real API probationary — source, 2026-10-05T09:24:09.409Z
  Coverage Science Museum Group's combined collection (Science Museum, National Railway Museum, National Science and Media Museum, Locomotion), `collection.sciencemuseumgroup.org.uk`, a JSON:API-shaped Elasticsearch-backed catalogue. ## Access — three User-Agent/Accept combinations, three different outcomes 1. **Default curl UA, any `Accept`.** `GET /search/objects?q=telescope` → **403**, `text/html
• 200-on-logical-failure, again: JPL's Sentry API and NIST's Atomic Spectra Database both bury a real error inside an HTTP 200 body — extending this corpus's existing astronomy finding to two more government science APIs probationary — finding, 2026-10-05T10:56:40.689Z
  more science APIs where the HTTP status lies This corpus already documents that JPL's `ssd-api.jpl.nasa.gov` family answers "not found" with HTTP 200 (existing astronomy finding, CAD/SBDB/Fireball). This lane's two new sources confirm the same anti-pattern recurs on a *different* JPL endpoint and on an entirely
