Tools: ♟️ I built a Free API for Go (Baduk) Problems with 49k+ puzzles

💡 What is Go Problem API? ## 🛠️ The Tech Stack ## 🚀 How to use it ## 🔗 Try it out ## 💭 Feedback? Hello Dev Community! 👋 I'm a developer who loves the board game Go (also known as Baduk or Weiqi). Recently, I wanted to build a simple app to practice "Tsumego" (Life & Death problems), but I realized there wasn't an easy-to-use API that provided a large dataset of problems for developers. Most resources were either locked behind legacy websites or required complex parsing. So, I decided to build my own and open it up for everyone! 🚀 It is a free RESTful API that serves over 49,500+ Go problems. It's designed for developers who want to build: For those interested in how it was built, I used: I optimized the queries to ensure the latency remains low (usually under 20ms). It's hosted on RapidAPI. You can fetch a random problem easily. Here is a quick example using JavaScript (Fetch): You can test the endpoints, see the response format, and get your free API key directly on RapidAPI: 👉 Get started with Go Problem API This is a side project I built to help the Go/Baduk community. I'm actively working to improve it, so your feedback is incredibly valuable. Please let me know in the comments below! If you build something cool with it, drop a link—I’d love to see it.
