  "summary": "A developer has open-sourced the full category tree for Kleinanzeigen.de, Germany's largest classifieds site, after reverse-engineering it due to the lack of a public API. The category tree consists of 15 top-level, 143 second-level, and 476 third-level categories, each assigned unique numeric and slug IDs. The source material, found on Dev.to, includes a full tree with IDs, a flat names-only version, and a lookup example, all available on GitHub under the MIT license. The developer encourages contributions to keep the category tree current as Kleinanzeigen continues to make changes.",
