Description
Solve CAPTCHAs with 2Captcha from the command line during browser automation.
Usage Guidance
Install only if you are comfortable sending CAPTCHA content, target page metadata, and related challenge data to 2Captcha and its human solvers. Use it only for authorized workflows, avoid sensitive or internal pages unless approved, and protect the 2Captcha API key stored in the environment or local config file.
Capability Assessment
Purpose & Capability
The artifacts consistently describe solving CAPTCHAs through the 2Captcha service, and the Python CLI implements that purpose directly via createTask/getTaskResult and balance requests.
Instruction Scope
The documentation clearly warns to use it only for authorized automation and says CAPTCHA images, page URLs, sitekeys, challenge IDs, and metadata are sent to 2Captcha and human solvers.
Install Mechanism
Installation is disclosed through skills.sh/OpenClaw plus a manual git clone and symlink flow; an optional README command uses sudo to link into /usr/local/bin, but it is visible and not automatically executed by the skill.
Credentials
Network access to api.2captcha.com, local CAPTCHA image reads, optional image URL downloads, and API key use are proportionate to a CAPTCHA-solving CLI but involve third-party processing.
Persistence & Privilege
The only persistent elements described are a local API key file and CLI symlink; there are no background workers, startup hooks, credential harvesting beyond the documented 2Captcha key locations, or destructive file operations.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install 2captcha - After installation, invoke the skill by name or use
