      "keyword": "[EXTRACTED_KEYWORD]",
      "domains": [
        {"domain": "[KEYWORD].io", "price": [PRICE_IN_USD]},
        {"domain": "[KEYWORD].ai", "price": [PRICE_IN_USD]},
        {"domain": "[KEYWORD].lab", "price": [PRICE_IN_USD]},
        {"domain": "[KEYWORD].tech", "price": [PRICE_IN_USD]}
      ]

2. Ensure that the keywords are specific, meaningful, and directly related to the content.
3. Avoid overly generic or irrelevant keywords (e.g., "chip", "software", "startups").
4. Keywords must not include or resemble domain extensions like ".io", ".ai", ".lab", or ".tech".
