Verid Description
Verid is an API designed for developers that focuses on monitoring webpage changes through structured data rather than relying on screenshots. It alerts users only when specific fields of interest change, such as price or stock status, by triggering a webhook based on customizable conditions. This approach emphasizes state monitoring over visual comparisons, offering features like structured data extraction, persistent state tracking, field-specific differences, and condition-based notifications all within a single workflow. Each monitoring instance operates according to a schedule defined via a comprehensive REST API that conforms to the OpenAPI 3.1 specification, allowing teams to manage configurations while Verid handles the backend infrastructure. The process comprises five distinct stages: fetching, extracting, differentiating, assessing predicates, and delivering results. Verid initially employs a static fetch method but can seamlessly switch to a headless browser when necessary, and if challenges arise, it can further adapt by using a residential proxy for enhanced access. This flexibility ensures that users can effectively monitor any webpage regardless of its complexity.

Gaffa is a REST API built for web scraping and browser automation, allowing developers to run real, full browsers at scale with a single API call. It removes the difficulty of managing headless browser frameworks, rotating proxies, CAPTCHA solving, and scaling infrastructure, all of which are handled automatically.
JavaScript-heavy and dynamic websites render exactly as they would for a human visitor by default. Beyond standard scraping, Gaffa supports AI-driven structured data extraction (extract data into a defined schema without writing CSS selectors), screenshot and PDF capture, infinite-scroll and form-filling automation, and clean Markdown conversion for feeding webpages directly into LLM and RAG pipelines.
A rotating residential proxy network keeps access reliable across regions, and a credit-based pricing model means teams pay only for the browser time and bandwidth they actually use. Gaffa is designed for AI engineers, data teams, and developers who want production-grade web data extraction without having to build and maintain their own infrastructure.

waiting
Waiting is a compact library designed to facilitate the process of waiting for specific conditions to be met. It fundamentally pauses execution until a designated function returns True, offering various operational modes. Additionally, Waiting is designed to work seamlessly with flux for simulating timelines. The simplest way to utilize it is by providing a function to monitor. It’s straightforward to wait indefinitely; if your predicate yields a value, that value will be returned as the output of wait(). You can also set a timeout, and if this period lapses without the predicate being satisfied, an exception will occur. The library polls the predicate at a default interval of one second, which can be adjusted using the sleep_seconds parameter. When dealing with multiple predicates, Waiting offers two efficient methods for aggregation: any and all. These methods are similar to Python's built-in any() and all(), but they ensure that a predicate is not invoked more than necessary, which is particularly beneficial when working with predicates that are resource-intensive and time-consuming. By streamlining these functions, Waiting enhances both the efficiency and user experience of handling asynchronous operations.

Checkist
To begin tracking changes on a webpage, first copy the URL of the desired page, paste it into the designated tracking form, and submit it to receive a screenshot. Once the screenshot is generated, choose the specific area you wish to keep an eye on for any modifications; for instance, if you are looking for price notifications or alerts for items back in stock, make sure to highlight the section that shows the price and/or the 'add to cart' button. Each time there is an update in this selected area, you will receive an email featuring a screenshot that highlights the differences between the last version and the most current one. Checkist can be utilized in numerous ways for both personal and professional purposes, including receiving alerts for restocked items and price reductions, monitoring competitors, and ensuring you stay informed about changes in legislation and administrative regulations. By leveraging this tool, you can efficiently streamline your monitoring processes and stay ahead in various aspects of your endeavors.
