Why We Exist
Even with CAPTCHA protecting your signup forms, sophisticated fake users still slip through. Here's why—and how we're different.
CAPTCHA does an excellent job at one thing: proving you're human. It blocks automated bots and scripts from flooding your signup forms.
But here's the problem: being human doesn't mean being legitimate.
Real Scenario:
A real person solves your CAPTCHA, enters user123@tempmail.com, and signs up for your free trial. They use your service, and when the trial ends, they simply create another account with user456@10minutemail.net. Same person, new disposable email, another free trial.
CAPTCHA sees this as legitimate because it is a human. But your business sees revenue loss, skewed metrics, and resource waste.
CAPTCHA Solves:
Blocks automated bots and scripts
Prevents mass automated signups
Stops credential stuffing attacks
Verifies human interaction
CAPTCHA Doesn't Solve:
Human-operated fake accounts
Disposable email abuse
Trial/promo gaming
Low-quality user detection
Disposable email services make it trivially easy for anyone to create unlimited temporary email addresses. These services are designed to be used and discarded.
Common Abuse Patterns:
- •Trial Farming: Creating multiple accounts to abuse free trials or premium features
- •Promo Abuse: Exploiting first-time user discounts and referral bonuses repeatedly
- •Content Spamming: Posting spam or malicious content without accountability
- •Review Manipulation: Creating fake reviews or ratings to boost or damage reputation
- •Data Pollution: Flooding your database with low-quality, unmaintainable user data
These aren't bot attacks—they're sophisticated users who understand the system and know how to game it. CAPTCHA can't help because these are real humans with real browsers.
API Armor doesn't replace CAPTCHA—we complement it. While CAPTCHA validates humanity, we validate email authenticity.
Real-time Disposable Email Detection
We maintain a constantly-updated database of 100,000+ disposable email domains from Certificate Transparency logs, community reports, and proprietary detection algorithms.
Smart Heuristic Analysis
Beyond simple domain matching, we analyze MX records, WHOIS data, domain age, and behavioral patterns to catch newly created disposable services before they appear in public lists.
Lightning-Fast API Response
Sub-50ms response times from our global edge network means validation happens seamlessly without impacting user experience.
Privacy-First Approach
We never store email content or personal information. We only validate the domain, keeping your users' privacy intact.
The most effective signup protection combines both approaches:
CAPTCHA
Blocks automated bots and verifies human interaction
✓ Automation prevention
✓ Human verification
API Armor
Validates email quality and blocks disposable addresses
✓ Trial abuse prevention
✓ Data quality assurance
Result: Comprehensive Protection
Stop both automated attacks and sophisticated human abuse. Ensure every signup is legitimate, trackable, and valuable.
Success Story:
"We had CAPTCHA enabled for years, but we were still losing thousands of dollars to trial abuse. After adding API Armor, our fake signup rate dropped from 23% to under 2% in the first week. The ROI was immediate."
