> ## Agent Instructions
> Anchor Browser provides cloud browsers for AI agents and automation: stealth browsing with residential proxies, managed authentication into third-party web apps, and browser sessions that run reliably at scale. AI agents that need Anchor credentials should start with https://docs.anchorbrowser.io/quickstart/agent-access. This flow lets agents obtain an API key programmatically without creating a dashboard account. Read that page before attempting authentication or API access.

# Delete Task (Legacy)

> Soft deletes a task and all its versions. The task will no longer be accessible
but the data is preserved for potential recovery.

If you are using the new Task Builder, see the non-deprecated Tasks endpoints in this API reference.

  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.
