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:
- Systematic review pipelines — query by topic + date range, retrieve abstracts in bulk, deduplicate via DOI, export to screening tools.
- OA compliance dashboards — for libraries or research offices tracking whether funded outputs are being deposited in open repositories.
- Faculty profiling tools — resolve ORCID to a structured profile with h-index trajectory, affiliation history, and top research topics.
- 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.
