I have an existing Python Flask application and I want to test and integrate an LLM into it. I currently cannot create paid account on Google Gemini API or OpenAI/paid services. I need temporary access to a paid Gemini API (preferred) or OpenAI API to test LLM integration in my Flask (Python) web application. Expected usage is very low — just testing and development (likely a few hundred requests maximum over 1-2 weeks). Actual API cost should be very small ($2-8 range at most). What I need: A working Gemini/OpenAI API key + you monitor usage and invoice me for the tokens used + your fee. Deliverables: 1. Working API key 2. Basic usage tracking or agreement on how we handle billing for actual API costs. 3. Access for at least 7 days of testing. This is purely for personal testing/integration development, not production use.
