Problem
AI agents often generate responses based on outdated or unverified information, leading to hallucinations and unreliable outputs. Standard search APIs return raw links without context, forcing agents to parse entire pages and struggle to identify credible sources or distinguish bias in the information they retrieve.
Solution
Flux provides a grounded search API specifically built for AI agents, delivering live web results with byline citations that help agents assess source credibility and recency. The platform includes a Lineage feature that extracts only the passages from a page or document that directly answer a query, with names and dates filled in for immediate context. Developers can integrate Flux through a simple API, with SDKs available for OpenAI, Vercel, and LlamaIndex, or test it through a built-in chat interface. The service supports tracking companies, reviewing case law, following markets, monitoring research, and staying current on news, all with ranked results and optional passage-level answers.
Target Audience
Primary customers are developers and teams building AI agents and applications that require real-time, verifiable web search capabilities, including those working with LLM frameworks like OpenAI, Vercel, and LlamaIndex.
