Extraction method guides
Everything you need to get data out of any page - CSS selectors, XPath, JSONPath, Regex, full-page hashing, and AI extraction. Each guide includes real examples with example HTML and JSON output.
How to Use CSS Selector Extraction
Target HTML elements by class, ID, or attribute and pull out their text. The fastest method for well-structured pages.
How to Use XPath Extraction
Navigate the full document tree with XPath expressions. More powerful than CSS selectors for complex conditions, attribute access, and partial text matching.
How to Use JSONPath Extraction
Query JSON API responses and embedded JSON data using JSONPath expressions - the JSON equivalent of XPath.
How to Use Regex Extraction
Run regular expressions against raw page source to extract versioned strings, counts, prices, or any pattern that appears in the HTML or text.
How to Use Full Page Hash
Detect any meaningful change on a page without configuring selectors. Verid normalizes the HTML and computes a hash - if anything changes, you hear about it.
How to Use AI (LLM) Extraction
Describe what you want to extract in plain English and let the AI figure out the rest. Works on any page, including JavaScript-heavy and unstructured content.
