Help Integrate an LLM API and Deploy It to the Cloud

I’m looking for someone to help with a small LLM integration and cloud deployment task. I need a simple Python or Node.js API that accepts text, sends it to OpenAI or Claude, and returns the response as JSON. You’ll connect one LLM provider, deploy the endpoint to a cloud platform, and add basic authentication, input validation, and error handling. Please keep API keys secure, test three sample requests, and provide the source code with brief setup instructions. I’ll provide the necessary access and cover API and hosting costs. If this sounds like a good fit, please share a relevant example and let me know when you can start.
