The Text Emotion Recognition API allows you to accurately identify and interpret the emotions expressed in a given piece of text.

The Expletive Detection API safeguards digital platforms by accurately identifying and filtering offensive language, ensuring a positive and respectful user experience.

The Verbal Expression Analyzer API swiftly classifies text as positive, negative, or neutral, offering real-time insights for informed decision-making.

"Empower your applications with our Expression Recognition API uncover emotions, assess opinions, and analyze attitudes for enhanced decision-making and user engagement."

The Expression Evaluation API is a versatile natural language calculator that can evaluate mathematical expressions and return the results in plain text. Simply input the expression to be evaluated, and the API will scan and compute the calculation, making it an easy-to-use tool for developers who want to incorporate a calculator function into their applications.

It utilizes artificial intelligence to identify and manage offensive language in user comments, fostering digital etiquette and enhancing online safety.

Expression Guard API: Seamlessly integrate advanced linguistic analysis into your platform, ensuring real-time content moderation for a positive user experience.

Test a regular expression against an input text and get every match with capture groups and named groups. Patterns run in an isolated worker with a hard time limit, so catastrophic patterns are stopped safely.

Parse any scheduler expression, get the next execution times in any world time zone, and a plain language description of the schedule. Validate schedules before they reach production.

Parse, validate, describe, and generate cron expressions. Converts cron syntax to human-readable descriptions and calculates next run times.
