Features and benefits

Confidence in data security

With ISO27001:2013 certification, robust technology and clearly defined policies and procedures, you can trust Email Hippo with your data.

See privacy policy for more information.

Consistent, parsed records

WHOIS records are intrinsically designed for humans to read and records come in different formats according to the choices made by an individual Domain Name Registrar and the Domain Name Registry.

For any serious application demanding data in a predictable, consistent machine-readable format, the standard WHOIS system will not work. This is where Email Hippo adds value to the WHOIS system by adding services capable of presenting the relatively chaotic structure of WHOIS records as reliable, predictable and machine-readable formats.

Machine readable dates

For ultimate in machine integration compatibility, Email Hippo returns dates and durations in ISO 8601 standard formats.

> 99.9% uptime

Fully load balanced and automatic fail-over systems dispersed across multiple data centers in multiple regions deliver enterprise-grade resilience.

See Service reliability for more information on availability and SLA.

Easy integration

See integrations to see how quick and easy it is to integrate with our services from over 19 different technologies and platforms.

Fanatical Service Quality Management

Email Hippo operational staff obsessively monitor services to ensure the best possible uptime and coverage.

Uptime and functional correctness are actively monitored on a minute by minute basis from multiple data centers dispersed across North America, Europe, and Asia.

Fast, transparent response times

Every query response includes stopwatch data that shows the time taken to execute the request.

Unrivalled performance

Strategic data centers in Europe, aggressive caching, global network delivery optimization and cloud-based auto-scaling deliver outstanding performance. Typical queries are answered between 0.2 to 1.5 seconds.

Thoughtful versioning

Endpoints are “versioned”. This means that Email Hippo can continue to release new functionality without “breaking” existing clients committed to integrating with our systems on legacy endpoints.

What it does

Email Hippo is used to query WHOIS records in real-time.

Service reliability

Like you, we care about the reliability of our services.

By using the latest, distributed cloud-based systems, we deliver fast response times together with an enterprise-grade uptime of more than 99.9%.

About our infrastructure

We operate three data centers geographically dispersed as follows:

Network traffic is optimized for fast, reliable global delivery using Cloudflare Argo.

Service level agreement

Our API has a stated SLA that ensures that we provide you with more than 99.9% uptime for our services.

See our full service level agreement for further information.

Concurrency

To preserve the operational integrity of the service to all of our customers, there is a maximum concurrency enforced by our systems.

Limits

Allowed throughput is 50 WHOIS queries per second.

Throughput exceeding these limits will receive HTTP response code 429 (too many requests) for subsequent requests for a duration of one minute.

Suggestions on how to manage throughput

If you experience or anticipate exceeding throughput limits, here are two ways to control query rates:

Large throughput requirement

For sustained throughput of more than 50 domain queries per second, please contact us about a private, dedicated service.

Frequently asked questions

Can I trust you with my data?

Great question. See Data privacy for more information.

How can I get a key?

How reliable is the API?

> 99.9% average availability with a defined SLA.

Does the system get slower when it’s busy?

No. All infrastructure is hosted in cloud based platforms with automatic scaling enabled. Automatic scaling kicks in at busy times to provide more hardware resources to meet demand.

Do you cache results?

To deliver the speed and reliability demanded by our customers, verification results are cached as follows:

Can I get my usage in real-time?

Not yet. This feature is in the development pipeline.

How does it work?

At a basic conceptual level, the process of querying WHOIS services is very simple. First, find the authoritative WHOIS server for a particular TLD. Next, connect to the server on port 43, query the domain and capture the response.

The hard bit is dealing with WHOIS services that are intrinsically configured to work against the process of querying domains in any form large volume scale. Additionally, the WHOIS system does not follow one, unified standard which means that the data returned from WHOIS services is very difficult to parse to anything that is useful for automation or integration purposes.

Email Hippo’s strength in dealing with the “hard bit” of the WHOIS system comes from years of experience in solving similar challenges in email verification.

Can I get blacklisted using this API?

No. It’s Email Hippo infrastructure that does the work.

Will anyone know that I am quering a domain?

No. It’s Email Hippo infrastructure that does the work.
