About Verid

Verid is an API-first web change-monitoring service designed for developers who need to track changes on any webpage without building custom scrapers. It fetches pages using static, headless, or proxy methods and extracts structured fields using six different extraction techniques, including LLM-powered AI extraction that locates fields described in plain English even when selectors break. The service only notifies users when predicate-driven rules fire, delivering alerts via HMAC-signed webhooks, Slack, Discord, or email. It provides per-field diffs, durable state tracking, and reliable delivery to ensure monitoring remains quiet and resilient. By combining fetching, extraction, and alerting into a single service, Verid eliminates the need for developers to maintain separate scraping and alert logic, making it ideal for tracking price drops, stock restocks, dependency updates, or API drift. The platform is built to handle dynamic content and changing page structures while minimizing false positives and unnecessary noise in notifications.
