GET /schema-org

GET /schema-org alias: /schema-org

Returns a well-formed Schema.org / JSON-LD document: @context is https://schema.org, @type is in the vocabulary, all required properties for the type are present, no context-array shadowing. Served as application/ld+json. Counterpart to /schema-org, which ships one of four violations.

expect: 200 OK with Content-Type: application/ld+json. Body is spec-compliant JSON-LD with a real schema.org @context and a vocabulary-valid @type. Build structured-data extractors against this, then flip hostname to chaos.catastrophic.io to test adversity.
