A powerful suite of APIs for developers including deep Email Validation (with DNS MX checks), OpenGraph URL Metadata Preview extraction, and a high-speed Profanity/Toxicity filter. Designed to be fast, reliable, and secure.
The Email Validation endpoint returns details about the email's validity, including syntax, domain type, and MX records. The URL Metadata endpoint provides OpenGraph data such as title, description, and images from a URL. The Profanity Filter returns a boolean indicating the presence of profanity and a censored version of the input text.
Key fields for Email Validation include `isValidSyntax`, `isDisposable`, and `deliverability`. For URL Metadata, important fields are `title`, `description`, and `image`. The Profanity Filter highlights `hasProfanity` and `censoredText`.
The Email Validation endpoint accepts an email address as a parameter. The URL Metadata endpoint requires a target URL. The Profanity Filter takes a text string to analyze. Each endpoint is designed for specific input types relevant to its functionality.
Each endpoint returns a JSON object structured with relevant fields. For example, Email Validation includes fields like `email`, `isValidSyntax`, and `deliverability`. The URL Metadata response contains `url`, `title`, and `image`, while the Profanity Filter provides `originalText` and `censoredText`.
Email Validation uses live DNS MX record lookups and checks against a database of disposable domains. URL Metadata is extracted from the HTML of the provided URL using OpenGraph tags. The Profanity Filter relies on a comprehensive local dictionary of banned words.
Common use cases include verifying user email addresses during sign-up, generating rich previews for shared links, and moderating user-generated content for profanity. These functionalities enhance user experience and maintain content quality.
Users can leverage the Email Validation results to filter out invalid or disposable emails, enhancing communication reliability. URL Metadata can be used to create engaging previews in applications, while the Profanity Filter helps maintain a safe environment by censoring inappropriate language.
Data accuracy is ensured through real-time checks for Email Validation and continuous updates to the profanity dictionary. The URL Metadata extraction relies on parsing current HTML content, ensuring that the information reflects the latest data available from the target URL.
