Return the category/attribute reference line for a given category hint. Use this BEFORE search_ads whenever you plan to set `category` or `attributes`. Input can be a broad category in English or German (cars, phones, apartments, jobs, etc.). The response includes the exact CategoryName and allowed attribute values to use.

Search Kleinanzeigen listings in Germany. HARD RULE: NEVER call search_ads without calling get_category_reference first, unless you explicitly set allowGeneric=true. HARD RULE: Call MCP tools directly (get_category_reference, search_ads). Do NOT call api_tool or any /KA/link wrapper paths. IMPORTANT RULES: 1. You may use up to TWO tool calls per user request: - First call get_category_reference if you need category/attributes. - Then call search_ads once with the resolved category/attributes. - Do not call search_ads more than once for the same user request. 2. MULTILINGUAL SEARCH - CRITICAL: Kleinanzeigen has both German and English listings. - For generic nouns (apartment, couch, musician, bicycle, etc.), ALWAYS use `queries` array with BOTH German AND English terms. - This performs OR search - finds listings in either language. - WRONG: {"query":"Musiker musician"} <- AND search, returns 0 results - RIGHT: {"queries":["Musiker","musician"]} <- OR search, finds all - Keep brand names as-is: "iPhone 14 Pro", "PlayStation 5", "BMW" (same in all languages) 2b. USER ALTERNATIVES (or/oder) - CRITICAL: When user mentions alternatives like "256 or 512 GB", "rot oder blau", "3 or 4 rooms": - If the user uses "or" / "oder" between alternatives, use `queries` to represent each alternative as a separate OR search. - If the user uses "and" / "und", keep the terms together (AND) in `query` and/or `attributes` (do NOT split into `queries`). - WRONG: {"query":"iPhone 15 256GB 512GB"} <- AND search, finds nothing - RIGHT: {"queries":["iPhone 15 256GB","iPhone 15 512GB"]} <- OR search, finds both variants - Works WITH attributes: {"queries":["iPhone 15 256GB","iPhone 15 512GB"],"category":"phones","attributes":{"art":"apple"}} - If you use `queries`, omit `query` (each entry must be self-contained). - If user mixes OR + AND (e.g., "256 or 512 AND white"), duplicate the shared AND terms into each `queries[]` entry. 3. Search EXACTLY what the user asked for - do not expand or modify criteria. - If user says "3 rooms", search for exactly 3 rooms, not 3-6 rooms. - If user says "under 10000 euros", use maxPrice=10000, not 15000. - If user says "less than 50000 km", use km=[;50000], not a higher value. 4. Prefer structured `attributes` for filters WHEN possible, but do not invent values. - Use ONLY valid values from get_category_reference (do not invent values). - Translate user-friendly filter terms to the valid enum values (e.g., "automatic" -> "automatik"). - If the user mentions a product name that implies a brand/model, map it to the listed value (e.g., "iPhone" -> art=apple in Handy_Telekom). - If the user mentions a value that is not listed/recognized (e.g., trim/variant like "Shelby", "GTI", "AMG"), DO NOT pass it as an attribute value (it will be ignored). Put it into `query` (or into each `queries[]` entry) instead. - When using `attributes`, you may use `query` OR `queries`. Use `queries` for OR variants (multilingual synonyms or "X or Y"); if you use `queries`, omit `query` and make each entry self-contained. 5. For vehicle brands/models (cars AND motorcycles), use attributes marke/modell ONLY when you can map to valid values. - `modell` must be a single valid model code (e.g., mustang, mustang_mach_e), not a free-form phrase. - Example: "Mustang Shelby" -> {"category":"cars","query":"shelby","attributes":{"marke":"ford","modell":"mustang"}} 6. For apartments, ALWAYS use zimmer/wohnflaeche attributes for rooms/size filters. 7. Category selection: - Only set `category` when the user explicitly mentions the domain/category (cars, motorcycles, apartments, phones, furniture, etc.) OR when required to apply `attributes`. - For specific named products/brands/models, call get_category_reference and set the broad category if it exists. - NEVER guess narrow subcategories (e.g. "konsolen", "wohnzimmer"). If you set `category`, use broad categories only. - If unsure, omit `category` rather than guessing. - Safe broad categories: cars, motorcycles, apartments, houses, electronics, phones, computers, laptops, bikes, furniture, jobs, fashion, pets. 8. If you include `attributes`, you MUST also set `category` (attributes are category-specific and won't work without it). 9. BEFORE calling search_ads, call get_category_reference when you plan to use category/attributes. 10. When using category/attributes, include categoryRefId from get_category_reference in search_ads. 11. If get_category_reference returns no suitable category, you may call search_ads without category but MUST set allowGeneric=true. 12. Include userText (verbatim user request) in search_ads so the server can recover typos/synonyms. HARD RULE (repeat): NEVER call search_ads without get_category_reference unless allowGeneric=true. Examples: - "musician jobs" -> {"queries":["Musiker","musician"],"category":"jobs"} - "apartment in Berlin" -> {"queries":["Wohnung","apartment"],"location":"Berlin"} - "used couch" -> {"queries":["Sofa","Couch","couch"]} - "bicycle for kids" -> {"queries":["Kinderfahrrad","Fahrrad Kinder","kids bike"]} - "electric cars in Berlin" -> {"category":"cars","location":"Berlin","attributes":{"fuel":"elektro"}} - "BMW diesel" -> {"category":"cars","attributes":{"fuel":"diesel","marke":"bmw"}} - "Ford Mustang Shelby" -> {"category":"cars","query":"shelby","attributes":{"marke":"ford","modell":"mustang"}} - "3 room apartment 50-80 sqm" -> {"category":"apartments","attributes":{"zimmer":"3","wohnflaeche":"[50;80]"}} - "PlayStation 5" -> {"query":"PlayStation 5"} - "iPhone 14 Pro" -> {"query":"iPhone 14 Pro"} - "cars under 10000" -> {"category":"cars","maxPrice":10000} - "iPhone 15 with 256 or 512 GB" -> {"queries":["iPhone 15 256GB","iPhone 15 512GB"],"category":"phones"} - "red or blue BMW" -> {"queries":["BMW rot","BMW blau"],"category":"cars"} - "3 or 4 room apartment" -> {"queries":["3 Zimmer Wohnung","4 Zimmer Wohnung"],"category":"apartments"}
