FAQ
Why can some sites not return full source?
Some sites use anti-bot controls, authentication, geo restrictions, or dynamic rendering, which can lead to incomplete or blocked responses.
What is the difference between text, links, and forms extraction?
Text extraction focuses on readable content, links extraction collects a[href], and forms extraction keeps form-related nodes like form/input/select/textarea.
How should I choose encoding and highlight options?
Use the encoding that matches the target site. Highlighting only changes presentation and does not alter the original response data.
