What People Are Saying

Peter Bethke | Cellainc.com

After looking at several APIs for spam detection, we decided on OOPSpam and have not regretted that decision. The API is well documented, fast, and the developer has been very responsive and proactive. Highly recommended.

Rebecca Shiles | The Kelly Companies

It is powerful but also endlessly customizable and the few questions we had were answered promptly and the support staff went above and beyond to help us with the integration.

Frequently Asked Questions (FAQ)

How does OOPSpam API work?

OOPSpam API uses many different measurements to determine what seems to be spam and what does not. This includes multiple outputs from Machine Learning algorithms, up-to-date blocklisted IPs lists, spam words, and many more custom rules. The user (you!) directs their content to run through OOPSpam API and will get a Spam Score. This score gives you control for how conservative or liberal you would like to mark as spam.

Why do you provide a Spam Score instead of giving a simple ‘yes’ or ‘no’?

Because in the real world, things are not black and white (or in this case, green and red)! What might be the best solution for one client could look very different than the next. We’ll give an example. Say you are a travel website offering high end tour packages. You unfortunately get a lot of spam in your contact form, but it’s also the biggest conversion tool you have. In this case, since missing a ‘real’ message would mean missing out on large amounts of money, you would want to be more liberal on what content you accept. On the other hand, if you have a travel blog where comments are nice to get but more inconsequential, you might want to be more conservative on what comments you accept so you don’t need to spend lots of time combing through potential real comments. We decided to provide this spam score as a way to give developers and website managers more control and ability to create something more custom to ‘WOW’ their clients .

What does the Spam Score look like?

The API will return Spam Score which will be a number between 0 to 6. Besides Spam Score, It will also contain other details. It is up to you to decide your threshold based on Spam Score. Usually, a score 3 or above can be considered as spam.

Is a request to the OOPSpam API logged?

Not by default, but you can enable it. For API users, add the "logIt" parameter to a request body. Learn more about this here.

Is OOPSpam GDPR compliant?

OOPSpam itself as an API is GDPR compliant. It does not store any data, so there is no data to identify or track a user. Read more in the GDPR Notice and Data Processing Agreement.

Do you have a WordPress plugin?

Yes! Here you go: OOPSpam WordPress plugin.

Can I use one key for multiple websites?

Yes. Once you have a key, you can use it in our WordPress plugin as well as on any other platforms.

How to get a key?

Either via OOPSpam Dashboard or RapidAPI marketplace. Check our documentation to learn how to access your key in both through OOPSpam Dashboard and RapidAPI.
