Audience
Developers and teams that need to monitor websites and APIs for specific changes and trigger structured alerts or webhooks
About Verid
Verid is a developer-first web change detection API for monitoring any webpage for changes through structured data, not screenshots. Instead of alerting when a page visually changes, Verid extracts the exact field you care about, such as price, version, stock status, API response value, or availability, then fires a webhook only when a predicate you define is true. It is built for state monitoring, not screenshot diffing, giving developers structured extraction, durable state, field-level diffing, and predicate-driven delivery in one loop. Every monitor runs on a schedule you set through a full REST API with an OpenAPI 3.1 spec, so teams write the configuration while Verid runs the infrastructure. The pipeline follows five stages; fetch, extract, diff, predicate, and deliver. Verid starts with static fetch, automatically falls back to a headless browser when needed, and can escalate to a residential proxy when a site is harder to access.

Checkist
Copy the URL of the page you would like to track for changes, paste it into the tracking form, and submit it to get a screenshot. On the generated screenshot, select the area you would like to monitor for changes. For example, for a back-in-stock or price alert, select the area with the price and/or add to cart button. Now, every time there's any update in this area of a page, we will send you an email with the screenshot highlighting the difference between the previous and most recent state. There are many ways you can use Checkist for your personal or business activities: from back-in-stock alerts & price drops to competitor monitoring and staying up to update to legislation and administrative rules.

waiting
waiting is a small library for waiting for stuff to happen. It basically waits for a function to return True, in various modes. Waiting is compatible with flux for simulated timelines. The most basic usage is when you have a function you want to wait for. Waiting forever is very simple. If your predicate returns a value, it will be returned as the result of wait(). A timeout parameter can also be specified. When a timeout expires without the predicate being fulfilled, an exception is thrown. Sleeping polls the predicate at a certain interval (by default 1 second). The interval can be changed with the sleep_seconds argument. When waiting for multiple predicates, waiting provides two simple facilities to help aggregate them, any and all. They resemble Python’s built-in any() and all(), except that they don’t call a predicate once it has been satisfied (this is useful when the predicates are inefficient and take time to complete).
