    Parallel

    Parallel Web Systems

    High-accuracy web search and research APIs for AI agents.

    Parallel gives AI agents programmatic access to the web through a suite of APIs — a Search API, a Task API for structured extraction, and a Deep Research API for multi-hop questions — all served from its own proprietary web index and retrieval stack. It optimizes for high-signal, low-noise context fed straight into a model rather than ranking URLs for human clicks. Pricing is per request (the Search API starts at $0.005 per call) with a free allotment to start.
