## Tools (as reported by the server, not verified)

- `search\_datasets`: Search StackData's catalog of 50k+ official statistical datasets \(SDMX/World Bank dataflows, China censuses and yearbooks, tariff schedules\). Multilingual: an English query finds Chinese-titled tables. Returns dataset ids usable with the other tools.
- `get\_table`: Fetch a STORED table whole, by dataset id \(families cn-nbs-census and cn-nbs-yearbook\): labelled rows × columns with original-language labels, English overlay, units, and provenance down to the source file. Ids look like 'cn-nbs-census:2010\_a0101a'.
- `tariff\_lookup`: As-of customs-tariff lookup: which measures/duty rates apply to a goods code in a jurisdiction \(eu, us, uk, jp\), optionally from an origin, on a date. Duty expressions are verbatim; every measure carries its legal citation. Not legal advice.
- `resolve\_data`: Ask a data question in English \('unemployment rate in Japan', 'compare GDP in Japan and Germany'\) — resolves to the best covering dataset and returns the observations, with coverage honesty \(missing countries are reported, never papered over\).
- `get\_structure`: The published structure of one dataset, free: its dimensions with every member code and label, frequencies, period coverage, the ISO3 countries it serves, and whether it is servable. Call this before get\_series to learn the codes to send. Dataset ids come from search\_datasets.
- `get\_series`: Fetch ONE series with every dimension named by you \(no guessing or relaxing\): dataset, ISO3 countries, an ISO period range and a member code for every dimension from get\_structure. Returns status ok/empty/refused with each value's provenance, and the missing country-periods listed. A bad request is
