SpecStream for Claude computer use

SpecStream is the live web data engine for teams and agents. Claude reads a screenshot and returns clicks and keystrokes. Playwright runs them in a SpecStream browser session over its connect_url, for $0.10 an hour charged by the second.

What you get

A full loop to copy
One Python file opens the session, runs every action Claude returns in order, answers each with its result, and closes the session.
No beta header
The script sends computer_toolset_20260801, the version Claude Opus 5.5 and the other current models take. The guide lists the header for each older version.
You pay for the time alone
Driven over connect_url, clicks and keystrokes add no charge. A 5 minute session is under 1 cent of browser time.

Set it up

  1. Run pip install anthropic playwright httpx on Python 3.10 or newer.
  2. Create a SpecStream key with a spending limit and set SPECSTREAM_API_KEY and ANTHROPIC_API_KEY.
  3. Save the guide's agent.py and run python agent.py.

The full setup guide has every step, with what to do if something doesn’t arrive.
