Questions about the API

How many usernames can I generate at once?

You can generate up to 50 usernames per request. Each username is unique and checked for basic availability patterns.

Does the profanity check work in multiple languages?

Yes! Our profanity detection covers 20+ languages and catches leetspeak variations, hidden words, and creative bypasses.

How does the API generate usernames?

The API generates usernames based on the email address you provide. It creates creative variations using the local part of the email and various word combinations.

How do you ensure usernames are appropriate?

Every generated username is automatically screened against our profanity database. You can also validate user-submitted names with our profanity check API.

Is there a free tier available?

Yes! The free tier includes 1,000 API calls per month for development and testing purposes. Commercial use requires a paid plan. Check our pricing page for details.

Are generated usernames guaranteed to be available?

Generated usernames are checked against profanity lists but not against your user database. You must verify availability in your own system before allowing registration.

What are the rate limits?

Rate limits vary by plan. Check our pricing page for details. Our plans support high-volume username generation for large user bases.

Can I generate usernames based on user input?

Yes! Pass the user's email address and the API will generate creative username variations based on the email's local part (before the @).

What types of usernames are generated?

The API creates variations of the email local part combined with random words, suffixes, and creative modifications to produce unique, memorable usernames.

Do you check for trademark violations?

No, our profanity check focuses on inappropriate content only. You are responsible for checking generated usernames against trademarked names and brand protection.
