Use sources in your application

Find the dataset

Browse the catalogue, or use the Datasources API to discover source IDs and metadata programmatically.

Check access and supported APIs

Inspect the source’s access_modes (which APIs can use it) and the plan it needs. While you have free credits, every standard-plan source is available. Some sources are available only through DeepResearch; licensed content may have separate access requirements.

Search or start a research task

Use exact dataset IDs in source filters, or describe the evidence you need in a DeepResearch brief.

Understand coverage

Availability, freshness and full-text coverage vary by source. Public records, licensed publications and web results have different access and use conditions. The catalogue is the place to check current details; data coverage and access explains how to interpret them.

All datasets

Every dataset in the public catalogue, grouped by category. “Access” shows which APIs can query the dataset. DeepResearch can also draw on additional sources that are not listed here; name the evidence you need in the research brief. For live details and pricing, see the platform catalogue, or call GET /v1/datasources to read the same list programmatically. 50 datasets across 11 categories, as returned by GET /v1/datasources.
