Very interesting service. I'm surprised this hasn't been asked yet since it's not on the site - but where do you get your data?

Also, this sentence in your TOU made me giggle a little:

> 3. Additional Restrictions.

> ... You may not create a link to this website from another website or document without telo’ prior written consent.

We have a number of data sources including our own proprietary data, telecom sources, public records, graph data and user supplied data.

That statement in our terms is something that we will revisit. ;)

Very useful and easy to understand API. I am working on a project in fraud detection and this data could be very useful if it is reliably available.

However, I tried with three different phone numbers and it gave an empty string for name, profile, gender, image, and address. Could you give a rough estimate of what percentage of phone numbers you able to provide this information for?

Please reach out to us directly if you are working on fraud mitigation. We have extensive insight into fighting fraud and the data that can be used to that end. Additionally, there is a special permissible use-case endpoint we are working on for specific business applications such as fraud mitigation. You may reach us at support@telo.com.
