How the data is handled
Correct and traceable first
Every record is cited
Each response carries the publisher, the exact source URL and when it was fetched, so you can show your work.
source_url · fetched_at
Nothing is invented
If the agency doesn't publish a value, the field is null. Derived figures like totals and rankings are labeled as derived.
null, not a guess
Freshness you can check
Every dataset reports when it last refreshed and whether it's stale, and every response says how old its data is.
X-Data-Age · data_as_of
Developers
Typed, versioned, ready for agents
One response format across every domain, an OpenAPI spec, generated Python and TypeScript clients, and an MCP server so AI assistants can call it directly.
