Default endpoint can be overridden with `FLARESOLVERR_URL` environment variable (default: `http://localhost:8191`). ## When to Use - `web_fetch` returns Cloudflare challenge page - curl gets 403 or "Just a moment" / "Checking your browser" ## Usage ```bash # Using default URL FLARESOLVERR_URL="${FLARESOLVERR_URL:-http://localhost:8191}" curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.get", "url": "https://example.com/page", "maxTimeout": 120000 }' ``` ## Response ```json { "status": "ok", "message": "Challenge solved!" or "Challenge not detected!", "solution": { "url": "final URL after redirects", "status": 200, "response": "...", "cookies": [...], "userAgent": "..." } } ``` Extract content from `solution.response`. ## POST Requests ```bash curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.post", "url": "https://example.com/api", "postData": "key=value&foo=bar", "maxTimeout": 120000 }' ``` ## Tips - `maxTimeout` is in milliseconds; recommend 120000 (120s) for complex challenges - Simple pages typically return in 2-5 seconds; timeout is just the upper limit - Response is full HTML; parse as needed - If status is "error", check `message` for details
