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.
Description
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.
