   Step 2: Make your first API call

   Send a POST to https://listloco.p.rapidapi.com/localize with your listing data and your X-RapidAPI-Key. Replace <YOUR_RAPIDAPI_KEY> with the key from your dashboard.

   curl

   curl -s -X POST "https://listloco.p.rapidapi.com/localize" \
     -H "Content-Type: application/json" \
     -H "X-RapidAPI-Key: <YOUR_RAPIDAPI_KEY>" \
     -H "X-RapidAPI-Host: listloco.p.rapidapi.com" \
     --data '{
       "marketplace": "amazon",
       "sourceLang": "en",
       "targetLang": "de",
       "listing": {
         "title": "Wireless Headphones Model XB-900",
         "description": "Wireless Headphones Model XB-900 with 30h battery life.",
         "brand": "SoundCo",
         "material": "Plastic",
         "size": "One Size",
         "color": "black",
         "quantity": 1
       },
       "dictionary": {
         "wireless": "kabellos",
         "headphones": "Kopfhörer",
         "with": "mit",
         "battery": "Akku",
         "life": "Laufzeit"
       }
     }'

   Node.js fetch

   const body = {
     marketplace: "amazon",
     sourceLang: "en",
     targetLang: "de",
     listing: {
       title: "Wireless Headphones Model XB-900",
       description: "Wireless Headphones Model XB-900 with 30h battery life.",
       brand: "SoundCo",
       material: "Plastic",
       size: "One Size",
       color: "black",
       quantity: 1
     },
     dictionary: {
       wireless: "kabellos",
       headphones: "Kopfhörer",
       with: "mit",
       battery: "Akku",
       life: "Laufzeit"
     }
   };
   
   const response = await fetch("https://listloco.p.rapidapi.com/localize", {
     method: "POST",
     headers: {
       "Content-Type": "application/json",
       "X-RapidAPI-Key": "<YOUR_RAPIDAPI_KEY>",
       "X-RapidAPI-Host": "listloco.p.rapidapi.com"
     },
     body: JSON.stringify(body)
   });
   const result = await response.json();
   console.log(result);

   A successful response looks like this (pass: true means all compliance gates passed):

   {
     "localized": {
       "title": "Kabellose Kopfhörer Modell XB-900",
       "description": "Kabellose Kopfhörer Modell XB-900 mit 30h Akku-Laufzeit.",
       "brand": "SoundCo",
       "material": "Plastic",
       "size": "One Size",
       "color": "schwarz",
       "quantity": 1
     },
     "gates": {
       "titleLength":        { "pass": true, "length": 38, "limit": 200 },
       "bannedWords":        { "pass": true, "violations": [] },
       "requiredAttributes": { "pass": true, "violations": [] },
       "preservation":       { "pass": true, "violations": [] },
       "glossary":           { "pass": true, "violations": [] },
       "backTranslation":    { "pass": true, "score": 0.08, "threshold": 0.25 }
     },
     "violations": [],
     "pass": true
   }

   Each gate in the response corresponds to a deterministic compliance rule enforced by ListLoco: title character limit, banned keywords, required attributes, model-number and unit preservation, and back-translation divergence. If any gate fails, pass is false and violations lists exactly what to fix.

What the compliance gates check

Every response runs six deterministic checks against Amazon Germany's published listing rules. The same input always produces the same result.

• titleLength — Title must be 200 characters or fewer (Amazon DE limit).
• bannedWords — Detects restricted German terms such as garantiert, bestseller, and antibakteriell that violate Amazon DE policy.
• requiredAttributes — Verifies brand, material, size, color, and quantity are present in the localized output.
• preservation — Confirms model numbers, numeric values, and measurement units (e.g. XB-900, 30h) survived translation unchanged.
• glossary — Checks that every term in glossary.preserve appears verbatim in the localized output.
• backTranslation — Re-translates the German output to English and measures lexical divergence from the source.
