What Is A Bad Words Filter API And Which Are The Best Ones

Many of us have to deal with user input, search terms, and circumstances where the input text can contain foul language or other inappropriate language. This frequently has to be filtered away.

Our Bad Terms Detection API automatically recognizes these foul words whenever they are used in a remark and censors them. You have likely heard the phrase “Global Village” used frequently. This is accurate in that the Internet gives us access to everything. We can effortlessly and communicate with anyone on the planet.

We are therefore somewhat fortunate to have lived during the internet era, because we have access to everything. From our couch, we can debate any concept. But the modern world also has certain drawbacks.

Some of the worst problems that the internet and the world community are dealing with include hacking, racism, cyberbullying, harassment, etc. The use of offensive language and hate speech in online comments is one of the problems that we have all undoubtedly encountered. And we’re here to address this issue by creating an API that automatically identifies offensive language and removes it from comments.

Building applications where users post (or interact with) content will inevitably require you to detect and filter profanity. These include, to mention a few, chat rooms for video games, comment sections, and social networking applications.

Anyone who owns a WordPress site knows how problematic spam and vulgar language can be. You should be cautious about profanity and spammers whether you operate a straightforward website with a few pages or a multi-user platform that offers tons of user-generated material for two main reasons:

Profanity will drive off potential customers, leaving you with a smaller bank account.
Your SEO rankings in Google and other search engines will be adversely affected right away by spammers.

Also, kids will be kids, and occasionally bad language may find its way into the user experience. Parents want to be certain that the software is safe for their kids to use. However, if a student’s tale was mistakenly marked for vulgarity, we don’t want to prevent them from entering.

The Children’s Online Privacy Protection Rule (“COPPA”) requires that every story be vetted by humans, however we might give tales with potential profanity more priority for moderator approval. When a story is flagged, a moderator reviews it first to determine whether the flag is accurate or false.

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!


PurgoMalum is a straightforward, RESTful online service for filtering and deleting offensive language, obscenity, and other information. The interface of PurgoMalum supports a number of customisation parameters and can provide results in plain text, XML, and JSON.

Based on an internal profanity list (you can, at your discretion, add your own terms to the profanity list using a request parameter), PurgoMalum is meant to eliminate words from input text (see Request Parameters below). As an example, “@” will be recognized as a “a,” “$” will be recognized as a “s,” and so on. It is meant to recognize character alternates that are frequently used in place of normal alphabetic characters.

Additionally, PurgoMalum makes use of a list of “safe words,” or neutral phrases that contain words from the profanity list (like “class”). these secure words are excluded from the filter.

The system can identify profanity in more than 100 different languages. The maximum character length for text while using the API is 1024. Ai Powered Content Moderator will provide an error code informing the user of the problem if the content it receives is larger than the permitted size.

A cognitive service called the APS Content Moderator API scans text for potentially unpleasant, dangerous, or objectionable content. When such content is discovered, the service tags the content with the necessary labels (flags). Afterward, your app can manage flagged material to abide by rules or keep the intended user experience.
