Search the Scopus academic database for papers using Boolean query syntax.

Common field codes:

• TITLE-ABS-KEY(term) — search title, abstract, and keywords (most useful)

• TITLE(term) — title only

• AUTH(name) — author name, e.g. AUTH("Smith J")

• AFFIL(institution) — author affiliation

• PUBYEAR > 2020 — filter by publication year

• DOCTYPE(ar) — document type: ar=article, re=review, cp=conference paper

Boolean operators: AND, OR, AND NOT Example: TITLE-ABS-KEY("machine learning" AND cancer) AND PUBYEAR > 2020

Read the scopus://search-syntax resource for the full syntax reference.

Search for author profiles in the Scopus author index.

Query field codes:

• AUTHLASTNAME(Smith) — last name

• AUTHFIRST(John) — first name or initials

• ORCID(0000-0002-1234-5678) — ORCID identifier

• AF-ID(60027950) — affiliation ID

Example: AUTHLASTNAME(Smith) AND AUTHFIRST(J) AND AFFIL(MIT)

Use scopus_get_author with the returned author_id to fetch full metrics.

Search for institution and affiliation records in Scopus.

Query examples:

• AFFIL(MIT) — by name keyword

• AFFIL(Harvard) AND COUNTRY(United States)

• AFFIL-ID(60027950) — by Scopus affiliation ID

Returns affiliation_id needed for author searches and filtering.

Retrieve full paper details from Scopus using any supported identifier.

Identifier types:

• scopus_id — Scopus internal numeric ID (e.g. "85123456789")

• doi — Digital Object Identifier (e.g. "10.1016/j.labeco.2024.102505")

• eid — Electronic ID (e.g. "2-s2.0-85123456789")

Returns: title, full abstract, authors with affiliations, keywords, subject areas, citation count, DOI, and open access status.

Retrieve a researcher's full Scopus profile by their Scopus Author ID.

Returns: h-index, total citation count, document count, current institutional affiliation, subject areas, ORCID (if available), and publication year range.

To find an author's ID, first use scopus_search_authors. Example author IDs: '7401234567' or '57209123456'.

Get the current total citation count for a paper.

Provide either a Scopus ID or a DOI — at least one is required. This endpoint is lightweight and cached; use it for quick citation lookups without fetching the full abstract.

Get a year-by-year citation timeline for a paper.

Returns how many times the paper was cited in each calendar year within the specified date range. Useful for tracking research impact and citation trends over time.

Requires a Scopus ID. Use scopus_search or scopus_get_abstract first to obtain the scopus_id.
