Halowerk Official Sources Directory is a paid API for AI agents from research.halowerk.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).
Filters a curated directory of authoritative bodies—standards organisations, registers, intergovernmental bodies—by subject and country, returning what each authority is actually authoritative for
Answers the two questions that open any serious piece of research. First, where does something stand officially: filter a curated directory of authorities, registers, standards bodies and intergovernmental organisations by subject and country and get, for each one, what it is actually authoritative for, which is the real answer rather than a bare list of links.
A list of authoritative organisations matching the subject and country filters, each entry describing the organisation's name, its domain of authority, and a clear statement of what it is officially authoritative for — giving substantive answers rather than bare links.
POSThttps://research.halowerk.com/v1/official-sourcesUse this endpoint when you need to identify the correct official or authoritative body for a specific subject area in a specific country or region — especially for research, compliance, legal due diligence, or academic sourcing where credibility of source matters. Prefer this over general web search when you need structured, curated results that tell you what an authority is actually responsible for, not just a list of government URLs.
