OpenAlex

Bulk-add one or more matching OpenAlex entity IDs to an owned collection without duplicating existing memberships.

Resolve a partial name or title to likely OpenAlex entity IDs before filtering or retrieving metadata.

Create a private, single-entity-type OpenAlex collection, optionally with an initial bounded set of entity IDs.

Permanently delete exactly one owned private OpenAlex collection and all of its collection memberships. This does not delete the underlying OpenAlex entities.

Download an OpenAlex-cached PDF or gzipped GROBID TEI file for a work. Choose the format matching the work's has_content flags. Each call currently costs $0.01, and source copyright terms still apply. Downloads are limited to 25 MB; compressed TEI must also remain within 25 MB after expansion.

Retrieve changed entity counts and JSONL/Parquet download details for one OpenAlex changefile date. Requires an OpenAlex paid plan; inspect GET_RATE_LIMIT_STATUS for daily capacity and current endpoint cost.

Get metadata for one private OpenAlex collection owned by the connected user.

Retrieve one item from the deprecated, frozen OpenAlex Concepts taxonomy for legacy workflows. Prefer Topics through GET_ENTITY for new work; use select to limit returned fields.

Retrieve one OpenAlex work, author, source, institution, topic, keyword, publisher, funder, award, taxonomy item, country, continent, or language by its supported identifier. Returns the provider's entity object directly; use select to limit its top-level fields.

Validate the connected OpenAlex API key and inspect daily budget, prepaid balance, reset timing, and current endpoint costs before expensive queries or downloads.

Use OpenAlex's deprecated legacy classifier to infer topics from a required title, optionally accompanied by an abstract. Not recommended for new projects; costs $0.01 per request.

List all available OpenAlex changefile dates and detail URLs. Requires an OpenAlex paid plan. Keep aggregate traffic below 100 requests per second and inspect GET_RATE_LIMIT_STATUS for daily capacity and current endpoint cost.

List one page of entity IDs in an owned private collection together with collection metadata and page totals.

List private OpenAlex collections owned by the connected API-key user, optionally finding collections that contain an entity.

Query the deprecated, frozen OpenAlex Concepts taxonomy for legacy workflows. Prefer Topics through QUERY_ENTITIES for new work. Returns one cursor-controlled page; keep aggregate traffic below 100 requests per second and monitor the connected key's daily USD budget.

Search, filter, sort, sample, select, or group one OpenAlex metadata resource other than works, including authors, venues, organizations, taxonomy, geography, awards, and enumerations. Returns one cursor-controlled page.

Search, filter, sort, sample, select, or group scholarly works. Returns one cursor-controlled page and its OpenAlex query cost; use the snapshot for whole-catalog exports.

Bulk-remove one or more entity memberships from an owned private OpenAlex collection without deleting the underlying OpenAlex entities.

Update a private collection's name or description, or change its entity type while the collection is empty. Provide at least one of display_name, description, or entity_type.
