About

The Parallel Search API is a web-search tool engineered specifically for AI agents, designed from the ground up to provide the most information-dense, token-efficient context for large-language models and automated workflows. Unlike traditional search engines optimized for human browsing, this API supports declarative semantic objectives, allowing agents to specify what they want rather than merely keywords. It returns ranked URLs and compressed excerpts tailored for model context windows, enabling higher accuracy, fewer search steps, and lower token cost per result. Its infrastructure includes a proprietary crawler, live-index updates, freshness policies, domain-filtering controls, and SOC 2 Type 2 security compliance. The API is built to fit seamlessly within agent workflows: developers can control parameters like maximum characters per result, select custom processors, adjust output size, and orchestrate retrieval directly into AI reasoning pipelines.

About

The world's most performant knowledge graph and semantic reasoning engine. Founded by three professors at the University of Oxford, Oxford Semantic Technologies emerged as a result of extensive research into Knowledge Representation and Reasoning (KRR), out of which came the most powerful knowledge graph and semantic reasoning engine on the market today, RDFox. As an AI reasoning engine, RDFox mirrors human reasoning principles. With unrivaled reasoning capabilities, relying on accuracy, truth, and explainability, it empowers the next generation of AI applications. By inferring new knowledge exclusively from factual data, RDFox ensures results are firmly grounded in reality. RDFox’s incremental reasoning capabilities cause the consequences of the rules-based AI to be applied to the database in real-time as data is added, changed, or removed, all without needing a restart. Only the relevant information is updated without needing to reanalyze the entire data set.
