AI agents should start at https://docs.anchorbrowser.io/for-agents, then get an API key with Agent Access at https://docs.anchorbrowser.io/quickstart/agent-access — no dashboard account required. Read those two pages before authentication or API calls. # Create Profile > Creates a new profile from a browser session. A Profile stores cookies, local storage, and cache. ## OpenAPI ````yaml /openapi.yaml post /v1/profiles openapi: 3.1.0 info: title: AnchorBrowser API version: 1.0.0 description: > Anchor Browser ([anchorbrowser.io](https://anchorbrowser.io)) provides cloud browsers built for AI agents and automation. Use this API to launch and control browser sessions, run natural-language web tasks, authenticate into third-party web apps with managed identities, and capture recordings — reliably and at scale, without operating browser infrastructure yourself. ## Core resources - **Sessions** (`/v1/sessions`): launch configurable cloud browsers — residential proxies, stealth browsing, captcha solving, profiles, extensions, recording — and connect over CDP with Playwright, Puppeteer, or any CDP client. - **AI tools** (`/v1/tools/perform-web-task`): state a goal in natural language and the built-in agent completes it inside the browser. Related tools fetch webpages, take screenshots, render PDFs, and execute code in a session. - **Tasks** (`/v1/task`): create, version, deploy, and monitor repeatable browser automations built to run reliably in production. - **Applications and identities** (`/v1/applications`, `/v1/identities`): managed authentication into third-party web apps — including multi-step logins and TOTP-based 2FA — so agents can act on behalf of users. - **Profiles** (`/v1/profiles`): persist cookies and login state across sessions. - **OS-level control** (`/v1/sessions/{sessionId}/mouse`, `/keyboard`, `/clipboard`): raw input for flows that resist DOM automation. - Plus batch sessions for running browser fleets in parallel, session recordings, webhooks, events, extensions, client certificates, and billing usage. ## Authentication Pass an API key in the `anchor-api-key` header on every request. Create keys at [app.anchorbrowser.io](https://app.anchorbrowser.io) under API Access. AI agents that have no key yet can obtain one autonomously through the unauthenticated [agent-access flow](https://docs.anchorbrowser.io/quickstart/agent-access) (`POST /v1/agent-access`). ## For AI agents and LLMs - Docs: [docs.anchorbrowser.io](https://docs.anchorbrowser.io), with a machine-readable index at [/llms.txt](https://docs.anchorbrowser.io/llms.txt) and the full corpus at [/llms-full.txt](https://docs.anchorbrowser.io/llms-full.txt). - MCP server for hosted browser control: `https://api.anchorbrowser.io/mcp`. - Official SDKs: `anchorbrowser` on [npm](https://www.npmjs.com/package/anchorbrowser) and [PyPI](https://pypi.org/project/anchorbrowser/). `DELETE` operations terminate sessions or permanently remove resources (profiles, identities, extensions); `GET` operations are safe and read-only. servers: - url: https://api.anchorbrowser.io description: API server security: [] paths: /v1/profiles: post: tags: - Profiles summary: Create Profile description: >- Creates a new profile from a browser session.
