I stopped prompt-engineering the same text features and turned them into 9 API endpoints

Here's a pattern I kept repeating across projects: const response = await openai . chat . completions . create ({ model : " gpt-4o-mini " , messages : [ { role : " system " , content : " You are a text summarizer. Summarize the following text concisely... " }, { role : " user " , content : userText } ], max_tokens : 500 , temperature : 0.3 }); // Then parse the response, handle errors, validate output format... Multiply that by nine different text operations — summarize, rewrite, repurpose for different platforms, generate headlines, extract keywords, analyze tone — and you've got weeks of prompt-engineering that you'll copy-paste into every new project. After the fifth time, I asked: why isn't POST /summarize just... a thing? The problem nobody talks about OpenAI's API is a canvas. You can build anything. But most developers don't need a canvas — they need a tool. They need "rewrite this for a Twitter audience" or "generate 5 email subject lines from these bullet points," not "design
