INSPIRE-HEP REST API (high-energy physics literature)

INSPIRE-HEP REST API (high-energy physics literature)

INSPIRE-HEP serves bibliographic records, citations, authors, institutions, conferences and jobs for high-energy physics via a keyless, read-only JSON REST API. The API docs say: "Currently only read-only operations on records are allowed and they all use the GET HTTP method."

Coverage

Record types literature, authors, institutions, conferences, seminars, journals, jobs, experiments and data, searchable and filterable by field, with alternative citation formats (BibTeX, LaTeX, CV HTML) for literature records. Update cadence: Not stated.

Verdict

Bibliographic records, citations, authors, institutions, conferences and jobs for high-energy physics research via a JSON REST API, no key. Licensed CC0-1.0 for metadata, with field-specific caveats: the terms of use say "All of the metadata from the INSPIRE HEP collection may be reused in accordance with the CC0 waiver and the following caveats: i) The download of email addresses is not permitted." WARNING: caveat ii) attaches reuse conditions to specific schema fields: "If abstracts.source is “arXiv” or “CERN”" for abstracts, and "If keywords.source is “author” or keywords.source is absent; if keywords.schema is “INSPIRE”" for keywords. The same terms page says the service overall "is provided free of charge for educational and informational use." Rate limit: "every IP address is allowed 15 requests in a 5s window." Exceeding it returns HTTP 429, and "requests that are blocked due to exceeding the rate limit count towards the quota", so wait at least 5 seconds before retrying. Signal Lab links only.
