Every API, one clean contract.

Search archive.org's catalogue. Filter by mediatype (texts/audio/movies/software/image/etree…), collection, creator, subject, language and year range; sort and paginate. Returns items with identifier, title, mediatype, creator, year, downloads, rating, collections and thumbnail/details URLs.

{
  "query": "apollo 11"
}

Full metadata for one archive.org item by identifier: title, creator, description, date, publisher, language, subjects, collections, license, rating — plus the COMPLETE file list (name, format, size, duration, source) with direct download URLs, and the item's reviews. Set include_files=false / include_reviews=false to slim the payload.

{
  "identifier": "OTRR_Dragnet_Singles"
}

Browse the items inside an archive.org collection by its identifier (e.g. 'nasa', 'librivoxaudio', 'prelinger', 'GratefulDead'). Same rich item rows as search, paginated and sortable; optionally narrow by mediatype within the collection.

{
  "collection": "librivoxaudio"
}

All public reviews and star ratings for one archive.org item: reviewer handle, star rating (0-5), review title, body and date. Reviews are embedded in the item record, so this returns every review in one call (no pagination needed).

{
  "identifier": "OTRR_Dragnet_Singles"
}

Just the downloadable files for one archive.org item (no heavy metadata/reviews): name, format, size, duration, source and a direct download URL for each. Useful for fetching the actual book PDF / MP3 / video / ZIP.

{
  "identifier": "OTRR_Dragnet_Singles"
}

Full-text 'search inside' one digitized book on archive.org: find a phrase within the book's OCR text and get the matching snippets with page numbers. The item must be a texts/book item with OCR (most scanned books are).
