# OhneMakler Mietspiegel API

Returns the Mietspiegel page for one city: per-year and per-area comparison tables (city vs district vs state vs country) plus the inline Chart.js series, including error-bar points `{y, y_min, y_max}` — upstream omits error bars for some regions, which is returned as `null`, never invented. Slugs are transliterated (ü→u, ß→ss); an unknown slug is a non-billable 404.
