List the maps Ultimaps can render: the world, continents, countries subdivided into states, provinces, counties or departments, and US ZIP code areas. Each row is {id, title, regionType, layers, regionCount, labels}. id is the mapId for render_map and get_map_regions; it is the map's slug on ultimaps.com (the last path segment, not the whole URL) and always means the current edition. regionCount is how many region keys a complete dataset needs. labels: false means the map has no region labels, so style.labels does nothing there. layers are the ids render_map's layers can turn on. Pass query to search ids, titles, region types and categories (e.g. "counties", "germany", "africa"). Only call this when you don't know the id: common ids such as world, united-states and europe just work, and an unknown id usually comes back with the closest ids.

Look up one map: title, regionType, regionCount, labels, layers, and its regions as {key, title}, 200 per page. You rarely need this before rendering. render_map accepts region names, codes and common aliases and auto-corrects typos, reporting what it matched. Use it to build a dataset covering every region of a map, to see how a map names its regions, or to resolve a key render_map could not match. query searches keys, titles and aliases, so no hits means the map really has no such region. Use offset for further pages.

Render a map of the world, a continent, a country, its states/provinces/counties, or US ZIP code areas as an image shown in the conversation. Color regions with ONE of these (choropleth and categories are mutually exclusive):

• choropleth: a number per region, e.g. {"values": {"California": 39.5, "Texas": 30.5}}. Classes, breaks and palette are picked from the data unless you set them.

• categories: a label per region, e.g. {"values": {"France": "Euro", "Poland": "Złoty"}}. Colors are assigned automatically unless you set colors.

• regions: explicit hex colors, e.g. {"Texas": "#1D4ED8"}. Also works on top of either mode as an override. Region keys can be names, ISO/FIPS-style codes or common aliases. Typos are auto-corrected, and every correction or unmatched key is reported with suggestions, so there is no need to call get_map_regions first. Get mapId from list_maps if you don't know it. Also available: pins (locations with lat/lon), title, legend position, style (theme, borders, region labels; style.labels.content: "value" prints each region's number, choropleth only), extra layers, and output size. dryRun: true validates and previews region matching and the color plan without rendering. Without an API key: 30 renders per hour and 5 per minute (dry runs count), PNG up to 1600 px wide, with Ultimaps attribution on the image. The default 1200 px width is right for viewing in chat. Larger widths and scales are for files and are saved to disk instead of shown. Formats: png, or svg with a Pro key. PDF is not available. Every render is also written to a file and the path reported. Relay that path: in a terminal client the inline image is visible to you but NOT to the user, and the file is the only thing they can open. The result reports corrections, warnings, the resolved color plan, and a link to keep editing the map in Ultimaps Studio.
