Original: Building an AI-Powered Lead Qualification API with Next.js 15 and Gemini 3.5 Flash

Short summary

A tutorial showing how to build a lead qualification API using Next.js 15 and Gemini 3.5 Flash that scores incoming leads 1-100 and assigns priority. The code is skeletal — the Gemini API call is stubbed out — and the article is light on implementation detail. The author promotes their agency at the end, reducing overall substance.

  • Skeleton code for a lead scoring API endpoint using Next.js and Gemini
  • Gemini API call is stubbed, not actually implemented in the article
  • Significant self-promotion for the author's agency reduces content value

Generated with AI, which can make mistakes.

Is this a good recommendation for you?
