Risk API: detect bad actors & prevent spam signups
A major pain point of running an online business is the number of bad actors trying to defraud you, whether that's via stolen credit cards, or by exploiting your free trials and creating thousands of fake accounts.
Over the past few years at Clearbit, we've had our fair share of fraudsters try to take advantage of us. The nature of our business has allowed us to build up a proprietary dataset of people, companies and IP addresses, which puts us in a great position to tackle the problem, and frankly gives us an unfair advantage.
Introducing the Risk API
Our new Risk API lets you detect bad actors, identify disposable email addresses and stop spam signups. Simply embed it in a signup form or a payment checkout, and we'll give you a risk score for every transaction.
We've been battle testing this API with some of our customers over the last three months, and the results are impressive. We've seen upwards of 95% of spam signups being detected.
Powering things behind the scenes are a combination of our proprietary data, device fingerprinting, and machine learning models. We look at whether an email address is disposable, whether the client is using a proxy, signup velocity, and more to determine an accurate risk level.
Since this API gets more useful as more people use it, we're giving everyone 50k free requests every month which should cover most people's needs.
Fraudsters keep getting better at solving CAPTCHAs and circumventing protections, leaving you in an arms race when you should be focusing on your business. The Risk API effectively detects bad actors today, and will continue to evolve and improve over time.
