Antideo is an API service that helps you validate your website leads by validating Phone numbers, Email addresses and looking up the IP reputation.
Validate International and local phone numbers
Validate a wide range of both national and international numbers worldwide. Use it with landlines, mobile, toll-free, VoIP, etc. For example today a valid mobile number is required within the registration process in some platforms, then SMS is sent and the user has to type it in to complete its registration. Allowing invalid numbers can increase the number of bogus users, abandonment of registration and it will cost more to send SMS to invalid numbers that won't be delivered. At very least using Antideo Phone validation endpoint will help differentiate between mobile, landline and other types of phone numbers.
Perform health check for any IP address
This health check is particularly helpful when you are using it for accepting user signups, checking orders against fraudulent indicators, or you're simply trying to stop the use of proxies from people visiting your website or mobile app. That being said proxies are not always bad, but it raises a red flag when someone from Middle East places an order on your website from an IP address in the US using an American credit card. You could be almost certain that this user had used proxy to hide their real IP address while using stolen credit card details. Such orders will more than likely result in a chargeback from your payment gateway and causing you financial damage and possibly penalties.
Control bad signups based on their email reputation
Stop accepting temporary (disposable) emails from your users when they signup to your newsletter, website or mobile app. Check the health of any email address and see if this is a known spammer or scammer. We will even detect if the email is from a free provider in case you want to act differently on that.

I like that Antideo provides thorough phone number validation, IP reputation checks, and email validation to guarantee the security and accuracy of my contact information. Even for individuals who are not tech-savvy, navigating around is made simple by the user-friendly design. Email deliverability is enhanced and bounce rates are drastically decreased using the technology. Furthermore, the customer service is prompt, kind, and available to help with any problems or inquiries. All things considered, Antideo is a dependable and useful tool for organizing and verifying contact data. Highly recommended!!
One aspect I dislike about Antideo is it takes longer validation process for really large datasets is one feature I do not like. Although the tool is generally effective, it might take a while to process large lists, which can be annoying when bulk email campaigns need to be completed quickly. Furthermore, integrating Antideo into an existing tech stack is less easy due to the restricted integration options with other email marketing and CRM solutions. The user experience would be greatly improved by making these improvements.
As a talent coordinator who manages a large set of emails, Antideo has been an excellent tool for me. The email validation feature is extremely effective, as it identifies invalid emails quickly. Before this, I had to check all the emails manually, and it cost me a lot of time. I personally recommend Antideo to anyone who wants to improve their email deliverability. It helps a lot!
Antideo is incredibly user-friendly and makes managing email validation, IP reputation checks, and phone number verification a breeze. Its integration with our systems was seamless, and the clear pricing is a major plus. It helps keep our data accurate and secure with minimal effort.
While Antideo covers the essentials well, it could benefit from features like enhanced security measures and multi-factor authentication to further protect against data breaches.
I'm really impressed with Antideo's ability to validate both national/local and international phone numbers. When validating national or local numbers, Antideo requires a two-letter country code in ISO 3166 format, ensuring that the numbers are accurate and correctly formatted for their respective countries. I will definitely continue using it
Offering more customization options for users, such as thresholds for email validation or specific parameters for IP reputation scoring, can cater to diverse use cases.

When it comes to identifying possible fraud and avoiding problems like chargebacks resulting from credit card fraud, the IP address health check tool is important.
Comprehensive Validation: IP addresses, emails, and phone numbers are all covered by ANTIDEO in one location. Using this one-stop shop saves time and effort over using several different tools.
Cost for Smaller Businesses: The expense of utilising ANTIDEO may be a barrier for startups or smaller companies, particularly if money is short.
Limited Free Tier: To let prospective customers fully explore ANTIDEO's capabilities before making a cash commitment, it would be advantageous if ANTIDEO offered a more generous free tier or trial period.
Fraud Prevention: We experienced problems with chargebacks and fraudulent orders in our e-commerce business. The IP address health check function of ANTIDEO has been quite helpful in spotting unusual activities and stopping fraud. It has aided us in identifying possible problems that could point to fraud, like mismatched locations or the usage of proxies.
