l1m.io is an AI-powered API platform designed to convert unstructured text and images into structured JSON using large language models (LLMs). Unlike typical LLM integrations that require prompt crafting, l1m.io allows you to define your output format using a JSON schema. Once defined, the tool ensures the AI output strictly conforms to that structure�no fluff, no hallucinations. It supports various LLM providers, including OpenAI and Anthropic, and can even be connected to local models like LLaMA via Ollama. l1m.io also includes caching, making repeated requests lightning fast. With no vendor lock-in, no data retention (unless cached), and full open-source flexibility, it�s the ideal backend companion for developers building AI-native workflows.
