3 Profanity Filter APIs & Low Cost Alternatives List In 2022

Do you need a tool to filter out offensive words but don’t know where to look? There is an answer right here and the best options.

What Is An API For A Profanity Filter?

A service that use the POST request method to return data in the JavaScript Object Notation (JSON) or XML formats is referred to as an application programming interface (API) that filters profanity. Developers use an API access key to access the API after subscribing to the service provided by an API vendor.

POST requests are used by an API to locate terms that should be deleted. The response body of the API contains the results in either JavaScript Object Notation or Extensible Markup Language (XML) (JSON).

Who Exactly Is A Profanity API For?

For programmers that want to include profanity text removal capability in their apps, there is a profanity API. An API for checking vulgarity will be useful for businesses that monitor internet interactions.

Applications that could profit from a profanity API include social networking platforms, chat forums, and online communities. Filters that eliminate offensive terms will be useful to website administrators for kids’ content.

Accounts that use foul language on search engine websites risk being suspended by Google and other search engines. Search Engine Results Pages (SERPs) are badly impacted when websites break search engine guidelines.

Websites that filter profanity have a more polished, reliable, and trustworthy appearance. As a result, companies using applications with profanity detection APIs can see an increase in client traffic.

The time it takes to integrate profanity filtering into applications will be reduced for developers that use APIs as opposed to writing the complete code from scratch. Businesses will be able to discover and remove inappropriate language automatically with APIs that check for profanity.

Bad Words Filter API

Bad Words Filter

In order to use natural language processing to decode the input into logical terms, the filter ignores punctuation, case, formatting, etc (NLP). Word obfuscation can be detected via word transformations, which can also reveal words with repetitive characters, excess whitespace, and special characters. In addition to finding and extracting undesired terms from the text, you can use this API to censor them from the text as well.

A text string or URL will be provided to the API, and it will then output a list of all the offensive terms it has found. You can also choose a different character to use in place of these objectionable words. You could use an asterisk or another word of your choice.

By visiting the Zyla API Hub marketplace and selecting the Bad Words Filters API utility utilizing the search API engine, you can find the best tool and filter every bad word. Of course, you can also browse all of the APIs that are readily available. Take advantage of this fantastic tool!
