ZeroEntropy

ZeroEntropy builds specialized, lightweight AI models for information retrieval and retrieval-augmented generation (RAG). Its zerank rerankers and zembed embedding models improve the accuracy of any search pipeline, and its hosted retrieval API lets developers create collections, index documents, and run relevance queries (top documents, pages, and snippets) with metadata filtering. The API is a versioned (/v1) HTTP JSON service with US and EU data-center endpoints, official Python and TypeScript SDKs, and API-key bearer authentication. ZeroEntropy is a portfolio company of Initialized Capital operating in the enterprise AI / search sector.

ZeroEntropy publishes 7 APIs on the APIs.io network, including Admin API, Collections API, Documents API, and 4 more. Tagged areas include Company, Enterprise Saas, Artificial Intelligence, Search, and Retrieval.

ZeroEntropy’s developer surface includes authentication, documentation, API reference, quickstart, signup flow, pricing, engineering blog, and 12 more developer resources.
