Redpine

Redpine searches licensed publisher collections and open-access research as full text rather than abstracts, and reaches Redpine-operated data integrations for news, company monitoring, earnings, aviation and legal research. Publishers are paid when their content is used.

Web search returns abstracts, paywalls, and citations that cannot be checked. Redpine licenses full-text research directly from publishers and institutions and returns the relevant chunk of the document, alongside a large open-access corpus. One query searches both.

Provenance by default. Every literature result carries its publisher, title, publication date, and a resolvable identifier such as a DOI.

Beyond literature, an account can hold data integrations, all operated by Redpine and reached through this connector. Which ones an account reaches depends on its subscription; Claude reads that list at runtime. Certain tools are billed against the same Redpine balance.

You see the price first. Any search can be previewed free: Claude sees the title, source and a snippet of every result plus the exact cost, then asks before spending anything. Unlock the three results that matter, not all 30. Results re-fetch free for seven days. Discovery, schema inspection, previews and balance checks are always free.

Built for questions where being wrong is expensive: clinical decisions, systematic review, financial and competitive analysis, and any work that has to survive a source check.

New accounts get free queries. Credits are bought on the Redpine dashboard; the connector never handles payment details. Requires a Redpine account, with OAuth sign-in on first use.
