# OpenAlex API: Query 250M Academic Works, Authors, and Institutions

[New Sources](https://anysite.io/blog/tag/new-sources/) [Research Data](https://anysite.io/blog/tag/research-data/)

Anysite now covers the **OpenAlex API** — one of the largest open scholarly graphs ever built. With this launch you can query **250 million academic works**, 90 million authors, 100,000+ institutions, and millions of journals, funders, publishers, topics, and concepts through a single unified REST surface.

All **19 endpoints** across 9 entity types cost **1 credit per request**. There are no tiered per-entity prices and no pagination surcharges.

## What's in the catalog?

The integration covers every major OpenAlex entity type:

- **Works (4 endpoints)** — lookup by W-id, DOI, PMID, or MAG-id; full-text search with 25+ filter parameters; forward citations; and reference lists.
- **Authors (2 endpoints)** — lookup by A-id or ORCID; search by country, institution, and metric ranges (h-index, cited-by count, works count).
- **Institutions (2 endpoints)** — lookup by I-id or ROR; search by country and type; geo-coordinates and associated-institution graphs.
- **Sources (2 endpoints)** — journals, repositories, and conference series; ISSN lookup; OA status, DOAJ membership, APC prices.
- **Concepts, Topics, Funders, Publishers (8 endpoints)** — lookup and keyword search for each entity.
- **Autocomplete (1 endpoint)** — cross-entity suggestions for any partial query string; optionally scoped to one entity type.

## Rich metadata on every work

Work records return far more than a title and DOI. Each response includes the **abstract**, full **authorship list** with ORCID and institutional affiliations, primary topic, up to 13 matched **topics**, OpenAlex and MeSH **concepts**, keyword tags, **funder** acknowledgements, **Sustainable Development Goal (SDG)** tags, the full cited-works list, and related-works suggestions. Open-access data covers `is_oa`, `oa_status` (gold / green / hybrid / bronze / closed), the best OA URL, and a PDF link where available.

The **FWCI** (Field-Weighted Citation Impact) field is included on every work, letting you compare impact across disciplines without being skewed by field-level citation norms.

## Search that actually filters

`POST /api/openalex/works/search` accepts 25+ parameters in one call. You can combine keyword, title, abstract, and full-text search with date ranges, type filters (`article`, `preprint`, `dataset` …), open-access flags, author/institution/source/funder/topic/concept IDs, SDG tags, and range operators on `cited_by_count` (e.g. `">500"`). The same range syntax works in author and institution searches for h-index, works count, and cited-by count.

## What you can build

Common patterns we've seen emerge immediately after this kind of launch:

1. **Systematic review pipelines** — query by topic + date range, retrieve abstracts in bulk, deduplicate via DOI, export to screening tools.
2. **OA compliance dashboards** — for libraries or research offices tracking whether funded outputs are being deposited in open repositories.
3. **Faculty profiling tools** — resolve ORCID to a structured profile with h-index trajectory, affiliation history, and top research topics.
4. **Citation graph crawlers** — walk forward (citations) and backward (references) one hop at a time to map intellectual lineage.

## Pricing

Every OpenAlex endpoint — lookups, searches, citation/reference lists, autocomplete — costs **1 credit per request**. Credits are pre-purchased, never expire, and are shared across all Anysite endpoints. At $0.001 per credit, a 10,000-work literature search pipeline costs $10 in API calls.
