## Tools (7)

- `compare_places`: Two UK areas of the same level side by side on the same published figures, each with its own period and source. Key figures by default.
- `fetch`: Read one UK area's overview figures by its canonical page path. Includes periods, sources, licences, gaps and citation links at the published level of detail.
- `get_place`: Published figures for one UK area: key figures by default, or every figure in one topic. Each figure has its period, publication date, rank, comparisons, source and a link to the figure on its page.
- `get_ranking`: Councils ranked on one measure across the UK, a nation or an English region, for the latest period. Measures each nation makes its own way (such as deprivation) are ranked within one nation only.
- `lookup_postcode`: The areas a Great Britain postcode sits in (council, constituency, ward, neighbourhood and more) with their codes and pages. A district (E8) or sector (E8 1) gives its councils. Northern Ireland postcodes are not available.
- `search`: Find UK area overview documents by place name for research, with canonical page paths, titles and citation URLs. Great Britain postcodes identify their published area. No Northern Ireland postcodes.
- `search_places`: Find UK places (nations, regions, councils, constituencies, towns, wards, neighbourhoods) and postcodes by name, with each one's official code, level and page URL. Also lists matching data layers.
