Is there a free LLM API?

Yes. UberLLM gives every new account free starter credits that work across all 380+ models — GPT, Claude, Gemini, DeepSeek, GLM, Qwen and more — through one OpenAI-compatible key, with no credit card required to begin. You can also earn more free credits by referring others. It is the fastest way to try many LLMs for free from a single API.
