About DeepAPI
DeepAPI exists so AI agents can act in the real world through one API key instead of a dozen provider accounts.
What we build
AI agents are good at reasoning but blind and handless by default. Giving one agent real capabilities today means signing up for a search provider, a scraping provider, an email provider, and more — each with its own keys, billing, formats, and failure modes. DeepAPI collapses that into a single API: web search, deep research with citations, structured extraction from public websites, GitHub, YouTube, X/Twitter, and PDFs, professional contact data, safe email sending, browser actions, image generation, and hosted agent memory — one key, one consistent JSON envelope, one prepaid balance, and per-call prices with no subscription. Failed calls are never charged.
Who is behind it
DeepAPI is built by a small team led by David Ondrej and operated by Vectal LLC, a US company based in Newark, Delaware. We use DeepAPI ourselves, daily, to run the agents that help build DeepAPI.
