Guidance

rank=blend weighs citations but is ~10-16x slower than bm25. Keep bm25 for fan-out, reserve blend for a small final set. before=ISO date (e.g. before=2020-01-01) gives a point-in-time view of the literature as of that date; this is the key differentiator vs OpenAlex's own free API, which has no such time-travel filter. text is the abstract, not the full paper.

Usage

The public endpoint is not live yet. Keys are invite-only during beta; contact shapeandfact+takedown@gmail.com.

Plain HTTP:

curl -s https://bipsearch.ai/search \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"corpus": "openalex", "q": "semaglutide cardiovascular outcomes", "limit": 5}'

Or via MCP, after adding the server once (see quickstart):

# after: claude mcp add --transport http bipsearch https://bipsearch.ai/mcp \
#   --header "Authorization: Bearer YOUR_KEY"
list_corpora()
search(corpus="openalex", q="semaglutide cardiovascular outcomes", limit=5)
