Migrate from OpenAlex or Semantic Scholar
Outcome: your existing metadata pipeline keeps working, with grounded answers added on top.
Field mapping
| Their field | Ours | Notes |
|---|---|---|
id / paperId | id (pap_…) | different namespace; map via DOI |
doi | doi | the reliable join key |
title | title | |
abstract / abstractInvertedIndex | abstract | plain text, not inverted |
tldr | tldr | |
authorships[] | authors[] | flatter shape |
host_venue / venue | venue | typed journal | conference |
open_access | open_access | |
cited_by_count | citation_count | |
| — | is_retracted | no direct equivalent; use it |
Verify each row against the Paper object before relying on it — field names here follow the v1 design and the OpenAPI spec is authoritative.
What you gain
Grounded answers with page-level citations, extraction over your own PDFs, and 2,000+ citation styles — none of which have an equivalent in a metadata-only API.
What changes operationally
Auth becomes a key with scopes rather than an anonymous or polite-pool request
Calls are metered in credits — budget before you migrate a bulk job
Licensing terms differ; re-read content-licensing before rehosting anything
