Großwald · machine-readable layer

Data API

Every published article and tracked entity as JSON. No key, no authentication, no rate limit. Base URL https://www.grosswald.org.

Endpoints

`/data/index.json`	Manifest — counts, every article slug with its last update, the entity list, the endpoint list. Start here.
`/data/changes.json`	Articles added and updated since the previous build, and the entities they touch. Poll this instead of re-crawling.
`/data/articles/{slug}.json`	One article: title, canonical URL, type, dates, excerpt, editorial facets, sources, entities.
`/data/entities/{slug}.json`	One entity: aliases, coverage timeline, last_covered, co-occurring entities, sources.
`/data/status.json`	Build status and freshness of this layer.
`/data/openapi.json`	OpenAPI 3.1 description of everything on this page.
`/data/sitemap.xml`	Every data endpoint with a lastmod date.
`/data/terms.txt`	Usage terms.
`/llms.txt`	Text index: overview, taxonomy, latest coverage.
`/llms-full.txt`	Every published article with date, type and excerpt.

Discovery

The catalog at /.well-known/api-catalog (RFC 9727, served as application/linkset+json) points to this page, the OpenAPI description and the status endpoint. The homepage carries the same pointers as RFC 8288 Link headers.

Conventions

Only published posts are mirrored — drafts and editorial holds are excluded by construction.
Article slugs are identical to the slugs in the public URLs.
sources come from the editorial source registry, not from link extraction.
Freshness is last_covered — when we last wrote about it, never a claim that a fact was re-verified.
Editorial facets (countries, domains, capabilities) are tag-derived. Machine-derived facets live separately under inferred.
CORS is open (Access-Control-Allow-Origin: *) on every data endpoint.
