You build agents. We give them eyes.

Expand is a web data API for AI agents that renders pages in a real browser and returns structured output rather than raw HTML. It addresses the problem of agents receiving incomplete or misleading page content when tables, icons, and hidden frontend state are lost during conversion. The service handles JavaScript rendering, residential proxies, and bot protection automatically for each request.

Expand Fetch returns Spatial Markdown that preserves tables, grids, and icons, along with hidden frontend state as JSON and an optional appendix containing secondary page regions. Highlights searches previously fetched pages for ranked, cited passages without re-fetching. Documents converts PDFs, office files, ebooks, and data files to Markdown; scanned pages and images are processed with a vision model. Video Transcripts and Audio Transcription handle YouTube URLs and audio files. Stealth Mode manages bot-detection avoidance and proxy rotation. Every output line links back to its source location on the page for verification. The API is available through Agents, SDK, CLI, and API interfaces.

Expand is intended for engineers building AI agents that need reliable, verifiable web data. It offers a free plan with initial credits, a pay-as-you-go option with prepaid credits that do not expire, and usage-based pricing where successful fetches and other operations consume credits. Failed, blocked, and empty requests cost nothing.
