Environment Variables

| Variable | Default | Description | |----------|---------|-------------| | GATESOLVE_API_URL | https://gatesolve.dev | GateSolve API base URL |

How It Works

1. Agent calls solve_captcha with the CAPTCHA type, site key, and page URL
2. GateSolve returns a 402 Payment Required with USDC amount
3. Agent pays via x402 (USDC on Base network)
4. Agent calls solve_captcha again with the payment token
5. Returns the solved CAPTCHA token

No API keys. No accounts. Just x402.
