Antideo

Antideo is an IP intelligence and data validation service that provides APIs for IP address geolocation, IP reputation checks, email validation and related lookups. Online businesses increasingly need to understand who is interacting with their websites and applications, whether a sign-up is likely to be genuine, and whether an email address supplied in a form is valid and safe to use. Without that information, organisations face fraudulent registrations, fake accounts, chargebacks and poor-quality marketing lists. Antideo's approach is to expose these checks as simple, developer-friendly REST APIs that can be called in real time at key points in a user journey, such as account creation, checkout or login. By returning structured data on location, network type and risk indicators, the service helps developers build their own rules for fraud prevention, content localisation and data quality, without having to maintain the underlying intelligence databases themselves. The service is designed to be lightweight and quick to adopt, with clear documentation and predictable response formats.

The IP location API returns country, region, city and other attributes for a given address, while IP reputation checks identify proxies, VPNs, Tor exit nodes, hosting providers and addresses associated with spam or abuse. Email validation verifies syntax and domain configuration, detects disposable or free email providers and flags addresses likely to bounce or be associated with fraud. Checks can be combined in a single workflow, so a sign-up can be screened for both network risk and address quality before an account is created. Results are delivered in JSON, making integration straightforward in most programming languages, and a dashboard lets users monitor usage and manage API keys. The service is fully cloud-hosted and scales with request volume. It is aimed at developers, e-commerce operators, SaaS providers, fintech companies and marketers who want low-cost, reliable enrichment and risk data within their applications and sign-up flows. Pricing starts from around USD 5 with a free trial; there is no permanently free version.
