Wavu

Need to stop spam comments, fake sign-ups or junk form submissions from reaching your site? Wavu is an anti-spam API that checks user-generated content so you can filter it before it gets published.

It sits in the AI content detector and text classifier space, and you call it from your own code or no-code and low-code setups.

Pricing is by monthly API calls, and every plan includes all features and unlimited websites.

Personal costs $9 a month for 1,000 calls with basic email support.

Pro is $35 for 50,000 calls and priority email support.

Business is $299 for 500,000 calls and priority support.

Enterprise is custom priced and adds more API calls, assisted installation and direct support.

The call limits are the main thing to check.

A small blog fits the entry plan, but a busy community or a site with many forms will move up quickly.

Wavu is a paid service, and the listing shows no free tier.
