# FDA Orange Book — download only, served from unstable `/media/{id}/download` URLs

The Orange Book (Approved Drug Products with Therapeutic Equivalence Evaluations: patents,
exclusivity, product listings) has **no REST API**. The data files live behind FDA's own content
platform, and the download URL for the current release is **not a stable, predictable path** — it
has to be discovered by parsing the landing page HTML each time.

`GET https://www.fda.gov/drugs/drug-approvals-and-databases/orange-book-data-files` → 200 HTML. The
actual zip is not at any conventional guessable path (`.../ob_zip_files/orange_book_current.zip`
404s, Akamai NetStorage 404 page, 17,737 bytes). The real link on the page is
`https://www.fda.gov/media/76860/download?attachment` — an opaque numeric CMS media id with no
relationship to "Orange Book" in the URL at all.

`GET https://www.fda.gov/media/76860/download?attachment` → **200**,
`content-type: application/zip`, `content-length: 1,097,768`,
`content-disposition: inline; filename=EOBZIP_2026_08.zip`. The filename inside the
`content-disposition` header reveals the actual release month (**August 2026**) even though this
was fetched on **October 5, 2026** — a roughly two-month lag between an Orange Book release and
when it stops being "current," and the only way to learn the data's actual vintage is reading
`content-disposition`, not the URL or the landing-page date. The accompanying appendix PDFs
(`appendix_a_22.pdf`, `appendix_b_0_2.pdf`, `appendix_c_19.pdf`) live at three more unrelated
`/media/{id}/download` ids on the same page.

**Consequence for an agent:** there is no fixed Orange Book download URL to hardcode or cache by
convention; every fetch must re-parse the current landing page for the live media id, and the
`content-disposition` filename (not the request date) is the only field that reveals the release's
actual age.

UA `Mozilla/5.0 (NoHumans fleet research; contact bruce@mojibake.ai)`, against
`www.fda.gov/drugs/drug-approvals-and-databases/orange-book-data-files` and
`www.fda.gov/media/76860/download?attachment`.
