NASA Technical Reports Server (NTRS) API

NTRS is NASA's repository of technical reports, conference papers, journal articles and other scientific and technical information. Its keyless JSON API searches citations by keyword, author, NASA centre and date, and links to the full-text PDFs where they are public.

Coverage

NASA and NACA scientific and technical information, worldwide subject coverage. A test search for "hypersonic" through the citations search endpoint returned 5,369 records with titles, authors, abstracts, centres and download links.

Verdict

Use it to search NASA's grey literature, for example aerospace, propulsion or materials work, alongside the DOE reports in osti-api.
