The problem

Bot registrations and fake accounts plague many API platforms, leading to skewed usage metrics, increased infrastructure costs, and a degraded developer experience. These illegitimate signups often exploit free tiers, consume valuable API keys, and can even contribute to rate limit issues for genuine users. Manually sifting through thousands of invalid accounts to identify real developers is a significant drain on operations and support teams.

Without robust email validation at the point of registration, your API platform risks attracting users who have no intention of building with your product. This impacts the accuracy of your lead scoring, complicates user segmentation, and makes it harder to nurture genuine prospects. Ensuring valid emails from day one is crucial for effective developer outreach and converting trial users into long-term partners.

How Verifyr solves it

Validate developer emails in real-time during signup, preventing fake and disposable accounts from accessing your API.

Identify catch-all domains, allowing you to flag or review suspicious signups that might indicate B2B lead quality issues.

Improve the accuracy of your API usage metrics and marketing segmentation by maintaining a clean developer database.

Concrete example


# Python example for API signup validation
import requests

def validate_email_for_signup(email):
    api_key = "YOUR_VERIFYR_API_KEY"
    response = requests.get(f"https://api.verifyrhq.com/v1/validate?email={email}&api_key={api_key}")
    data = response.json()
    if not data.get("valid") or data.get("disposable"):
        return False, "Invalid or disposable email."
    return True, "Email is valid."

# In your signup logic:
# is_valid, message = validate_email_for_signup("dev@example.com")
# if not is_valid:
#     display_error(message)

Frequently asked questions

How does Verifyr prevent bot registrations on my API platform?

Verifyr helps by validating emails in real-time at signup. It detects common indicators of bot activity, such as disposable email addresses, ensuring that only legitimate emails can proceed to create accounts and obtain API keys, thereby reducing spam and abuse.

Can Verifyr integrate with our existing signup forms?

Yes, Verifyr's API is designed for easy integration into any signup flow, whether you're using a custom form or a third-party authentication service. You can call the API during form submission to validate the email before account creation.

What if a legitimate developer uses a catch-all email?

Verifyr identifies catch-all domains, allowing you to implement a custom policy. You might choose to flag these for manual review, apply stricter rate limits, or require additional verification steps to balance security with legitimate B2B developer signups.
