List all document collections accessible to the authenticated API key.
/api/v1/search/collectionsAuthorization
BearerAuth API key authentication. Pass your key in the Authorization header as Bearer sk_live_.... An X-API-Key: sk_live_... header is also accepted as an alternative. Keys are created in the Redpine Connect dashboard under Settings > API Keys.
Keys come in two kinds. A live key (sk_live_...) searches real content and spends credits. A sandbox key (sk_test_...) returns canned results at no cost and never reaches licensed content, so you can build and test an integration before spending anything. Sandbox responses have the same shape as live ones and every result is marked synthetic, so going live is a matter of swapping the key. Check the X-Billing-Mode response header to confirm which you are using.

Free. Journals present in your scope of the collection, ranked by h-index (each with its journal_metric.impact_factor, an impact factor computed by Redpine from OpenAlex citation data with the JIF formula. It is not Clarivate's Journal Impact Factor. Journals that publish many news items, letters and editorials (for example BMJ, JAMA, The Lancet) score far below their JCR figure, because OpenAlex classifies those items as articles.), or with `topic` by the relevant content each journal holds on it. Only journals anchored to the metrics table count as proved; sampled, title-only and unresolved entries are reported beside the total. Each journal carries the ISSNs to filter a search on.
Assisted search (verified results only) POST
Agentic search: the query is interpreted, one or more internal searches are planned and run, every candidate is verified as actually addressing the query, and only verified results are returned. **Billing differs from `/search/query`:** only delivered, verified results are charged. A clarification request or an honest no-results answer costs nothing. Internal search fan-out and LLM tokens are absorbed by Redpine. Accepts the same `filters` as `/search/query`, applied to every internal search.
