Native IUAM task

POST mode: "iuam" with the protected URL and a proxy. Compatibility clients can keep task types such as AntiCloudflareTask or TurnstileTask without a sitekey.

curl -X POST https://api.xsolve.me/task \
  -H "X-Api-Key: <Your API Key>" \
  -H "Content-Type: application/json" \
  -d '{
    "mode": "iuam",
    "url": "https://example.com/protected",
    "proxy": "http://user:pass@host:8080"
  }'

Turnstile vs IUAM

  • Use Turnstile when the page exposes a sitekey.
  • Use IUAM for Cloudflare challenge / interstitial pages that gate the document itself.
  • IUAM expects a proxy so the clearance matches the client IP.
