GET /api/v1/entities/search with a subject to find curated articles
whose extracted themes mention a topic — a case-insensitive substring match
against metadataJson.themes. Unlike ticker / person / company /
organization, subject-only queries do not fill matchedEntity.
Limited to enabled publications curated for chat. Free, no auth required.
Request
The endpoint requires at least one ofticker, company, person,
organization, subject, or author. Multiple entity inputs are matched
as alternatives; author and the other filters narrow the results.
Set
sort=earliest for oldest first. Keep the same filters and sort when
following nextCursor. Invalid parameters, reversed date bounds, or an invalid
cursor return 400.
Response
publishedAt, most recent first by default (sort=latest).
Use this to browse a named theme by recency. Broad “what are analysts saying about X?” research
still belongs on /api/v1/search.
