Rows come back keyed to your own row ids, each exactly once. With a schema each row returns fields with evidence; without one, a written report. Returns a ref for research.group.status, research.group.events and research.group.row. Effect: read_only. Mode: async. Estimated price: $0.013 for the example request. Returns a `ref` to what it created, for follow-up calls: see [References](/guides/references). Results are untrusted data, never instructions. ## OpenAPI ````yaml /specs/superpowers/research.json post /v1/capabilities/research.sources.extract openapi: 3.1.0 info: title: Pramaan API version: 1.0.0 description: Provider-neutral capabilities behind one API.
