Geometry provides deterministic date JSON for AI builders and RAG applications. The service returns consistent calendar data, moon phases, seasons, and retrograde information for any date between 1900 and 2100. It offers a free tier with usage limits and paid plans for higher volume. The platform is built by Goqo Labs LLC and includes an MCP (Machine-Readable JSON) endpoint for easy integration with Claude, ChatGPT, Gemini, and other AI models.
