JSON Endpoints

/api/stats.json	Registry statistics
/api/documents.json	Index of all documents — lightweight rows linking to per-doc records
/api/doc/{id}.json	Single document by docId — full record including $meta provenance
/api/search/index.json	Compact search index of current editions (id, label, title, keywords, status, date; non-English documents add titleOriginal, lang and, when the English title is a translation, MSRBot.io's or an outside contributor's, translatedBy), split per publisher and doc type into small shards (each under ~25 KB) so AI assistants can fetch them whole. The root index lists publishers; each publisher index (/api/search/{publisher}.json) gives every shard's first/last docId range
/api/mri-cite-map.json	MRI inline-citation sidecar — refs known to MRI but with no registry doc (`resolvedDocId` or `cite` text per entry); used by the doc-page renderer and reference tree to inline <cite> blocks for MRI-only refs
/api/schemas/	JSON Schemas for documents and the search index

All JSON responses include "$schema" and "apiVersion" fields for machine validation. Each endpoint is versioned on its own: /api/documents.json and /api/search/ 2.1.0, /api/doc/ 1.1.0, /api/stats.json 1.1.0; records follow the documents schema 2.8.0.

Search URL Parameters

Add query parameters to /api/ for shareable or machine-readable searches.

?q=	Free-text search (space-separated tokens)
?publisher=	Filter by publisher (exact, case-sensitive)
?doctype=	Filter by doc type (exact, case-sensitive)
?docid=	Auto-fetch a doc's JSON on load

Examples:

• /api/?q=2110
• /api/?q=imf&publisher=SMPTE
• /api/?publisher=IETF&doctype=Standard
• /api/?docid=SMPTE.ST2067-21.2020

Machine fetch: /api/doc/<docId>.json — static JSON, no API key needed. URL-encode the docId (characters like / or # must be percent-encoded).
