CitedEvidenceResearch APIs

Migrating from legacy clients

Drop-in swap with a handful of host changes.

Our API is wire-compatible with api.openalex.org. In most cases you change the host, keep every path, filter, and cursor identical.

Base URL

Replace https://api.openalex.org with https://scholar.citedevidence.com/v1/oa. All downstream paths (/works, /authors, etc.) remain unchanged.

Identifier handling

We accept record IDs such as W123 and A123, namespaced prefixes (doi:..., orcid:..., ror:..., issn:..., pmid:..., pmcid:..., mag:...), and full URL identifiers (https://doi.org/...) exactly like the legacy API.

What changes

  • Use your API key instead of the legacy provider's. The mailto polite-pool parameter still works.
  • Our API returns the same JSON schema plus a small set of additive fields (we never remove or rename compatibility fields).
  • Snapshot releases live under /v1/oa/snapshot; per-entity manifests and per-release dates mirror the upstream layout.

Examples

  • GET/v1/oa/works?filter=publication_year:2024&per_page=50

    Same filter grammar as the legacy API.

  • GET/v1/oa/authors/orcid:0000-0002-1825-0097

    ORCID lookup works identically.

  • GET/v1/oa/works/W2741809807?select=id,title,cited_by_count

    Field selection supported.
