  title: Notte Agents Page API
  description: Notte is a REST API for web browser and agent infrastructure for AI. It creates cloud browser sessions, runs autonomous web agents from natural-language tasks, exposes a perception layer to observe / step / scrape live pages, performs one-shot scraping and AI web search, and manages personas, vaults, profiles, secrets, file storage, and serverless functions. The core framework is open source (SSPL-1.0). This document models the primary documented surface; see https://api.notte.cc/openapi.json for the full machine-generated specification.
