capmonster
Solve CAPTCHAs (reCAPTCHA v2/v3, hCaptcha, Cloudflare Turnstile, image CAPTCHAs) using CapMonster Cloud API. Use when browser automation encounters CAPTCHA challenges.
Why use this skill?
Integrate CapMonster Cloud into OpenClaw to automatically solve reCAPTCHA, hCaptcha, and Cloudflare Turnstile challenges during your browser automation tasks.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/easonc13/capmonsterWhat This Skill Does
The CapMonster skill allows OpenClaw agents to programmatically bypass common web-based CAPTCHA challenges during browser automation tasks. By integrating with the CapMonster Cloud API, the agent can identify, submit, and resolve CAPTCHA tokens for reCAPTCHA v2/v3, hCaptcha, and Cloudflare Turnstile without human intervention. This skill is essential for maintaining session persistence during web scraping, account management, or automated workflow execution when websites protect themselves against bot traffic.
Installation
To integrate this skill into your environment, run the following command in your terminal:
clawhub install openclaw/skills/skills/easonc13/capmonster
Ensure you have a valid CAPMONSTER_API_KEY defined in your environment variables, as this key is required to authenticate requests to the CapMonster Cloud infrastructure.
Use Cases
This skill is ideal for complex browser automation scenarios where manual interaction is blocked. Common use cases include: 1. Automated e-commerce product monitoring that triggers protective CAPTCHAs. 2. Lead generation scraping on sites requiring hCaptcha. 3. Managing automated logins for services that use Cloudflare Turnstile. 4. Large-scale data harvesting that requires frequent reCAPTCHA v3 token generation.
Example Prompts
- "Check the current account balance on my CapMonster account to ensure I have enough credits for today's tasks."
- "Go to the login page at [target_url], detect if there is a CAPTCHA, extract the site key, and use the CapMonster skill to solve it so I can proceed."
- "Solve the reCAPTCHA v2 challenge on the target page using the site key [site_key_value] and submit the response token into the browser input field."
Tips & Limitations
Success depends heavily on accurate site key extraction. Always verify the DOM structure, as some websites randomize their class names. Be mindful of the cost per 1,000 solves, as high-frequency automation can quickly deplete your account credits. While effective, CAPTCHA solvers are not foolproof against sophisticated anti-bot systems like fingerprinting; use this in combination with other anti-detection browser techniques for the best results. Always handle API errors gracefully by implementing retries if a token is rejected by the target website.
