Alix5sec Solver API

The Solverify Alibaba x5sec NoCaptcha Solver API creates a task for pages protected by Alibaba's x5sec NoCaptcha interstitial (the "Sorry, we have detected unusual traffic from your network" slide-to-verify page) and returns the x5sec cookie plus all other cookies set on the domain in solution.cookies.

Request Parameters

Field	Required	Description
`clientKey`	Yes	Your API key.
`websiteURL`	Yes	Full URL of the page protected by x5sec NoCaptcha.
`useragent`	No	User-agent string to use for the browser session. Max 512 characters.
`proxyType`	Yes	Proxy type. Only `http` is accepted.
`proxyAddress`	Yes	Proxy IP address or hostname.
`proxyPort`	Yes	Proxy port. Numeric string, 1 to 5 digits.
`proxyLogin`	Yes	Proxy username.
`proxyPassword`	Yes	Proxy password.

The x5sec cookie is IP-bound. A proxy is strongly recommended — replaying the cookie from a different IP than the one that solved the challenge will not lift the block. Use the same proxy for any follow-up business request.

If you provide useragent, use a desktop Chrome or Chromium user-agent. Firefox, Edge, Opera, iOS, and Android user-agents are rejected.

solution.value contains the x5sec cookie value. solution.cookies contains all cookies captured from the browser session, including x5sec. Replay the full cookie set (not just x5sec alone) against the target domain — some Alibaba endpoints require accompanying session cookies (xman_t, xman_f, cna, etc.) alongside x5sec to lift the block.

Timeout

Alibaba x5sec tasks can run for up to about 90 seconds before timing out internally.

Next Steps

After creating an Alibaba x5sec task, poll the Get Task Result API with the returned taskId. For validation and capacity errors, see Solverify API Error Codes.
