Below you will find the documentation on our API, it's very easy to use and requires SSL.

The response time for our API is between one second and 70 seconds. Since API's are meant to be fast by nature, we limit the amount of time we spend validating an email address. So if we encounter a slow mail server or a mail server with a greylisting algorithm you will get an unknown result. You can always re-validate those conditions, uploading a file to the bulk email validator.

On average 96-98% of all domains will return in 1 to 5 seconds, there are a handful of domains that run off Postfix/Dovecot that have a 20 second connection time for real-time validations and a very small fractional percentage of other domains that are very slow to respond to SMTP inquires. All the major ISP will return in 1 to 3 seconds, which is usually the majority of most email distribution.

The API will return these results in a JSON format using the "Validate" method.
