Hey, it's Maciej 👋

I am 🧙 Software Engineer and 👾 Security Researcher ( 🏆 8 x Listed in Google's Hall of Fame)

I realized that generating JSONs from LLMs should be easy and perfect, but it is NOT. That's why I built JsonGPT API.

JsonGPT API makes it incredibly easy to get the AI-generated JSON data you need. I built it because:

Save time ⏳ - One simple endpoint to get AI data for new project, making everything work seamlessly without a lot of code
Avoid headaches 🤕 - Parsing generated JSON from LLMs is not simple. I invested significant time to perfect it
Grow quickly 🚀 - The more you build, the more you learn, the more you earn

Now, I can spend less time on repetitive tasks and focus on what truly matters - building my business. Join me on this journey 😊
