Compared to Long Acting ISP Proxies, they offer higher IP purity, lower ban risk, more stable connection performance, and longer session retention — improving target website pass rates while maintaining strong network performance. They're ideal for business scenarios that demand high stability, anonymity, and risk-control pass rates. **Best suited for:** * Fine-grained cross-border e-commerce operations * High-value data collection * Financial/brand sentiment monitoring 9HTTP provides round-the-clock technical support.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://doc.9http.com/en/proxies/premium-isp-proxies.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
