Verid guides
How every part of Verid works, start to finish - what a monitor is made of, how to get data out of any page with CSS selectors, XPath, JSONPath, Regex, full-page hashing or AI, and how alerts are decided and delivered. Every guide includes real config and real output.

Extraction methods
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.
.product .priceHow 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.
//span[@id="price"]How to Use JSONPath Extraction
Query JSON API responses and embedded JSON data using JSONPath expressions - the JSON equivalent of XPath.
$.items[0].priceHow 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.
v(\d+\.\d+\.\d+)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.
sha256(normalized html)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.
