Today in APIs: Mailgun Email Validation API, Cloudmade's Authorization API, and 12 New APIs

Mailgun launches new API to verify emails in webforms. Cloudmade's API launched for clients to securely authorize against CloudMade's servers. Plus: Beer mapping, the most profane API ever, and 12 new APIs.

Mailgun's Guardpost API Makes Email Validation Easier

The Mailgun API, called "Guardpost," validates emails typed into forms by users. A Mailgun account is required to use the service, but use of the API itself is free.

The documentation reveals that the API checks email addresses a number of ways: it validates address based off syntax checks (RFC defined grammar), uses DNS validation, spell checks, and if available, Email Service Provider (ESP) specific local-part grammar.

According to Mailgun's blog post on the API, the API addresses what seems like a straightforward problem--is this email address valid?--but is in difficult to pull off:

"We suggest using Guardpost as part of your email collection form to reduce typos and false address submission in conjunction with a link emailed to the address to confirm the email is valid (double opt-in). Of course, you can use Mailgun to send the double opt-in email, as well. This is not intended to be a bulk mailing list cleaning service and we reserve the right to disable your account if we see it being used as such."

The reason why it's such a tough but to crack is that email syntax can be complex, making it hard to successfully apply a rule and be right; there's no definition of valid syntax; and because the Internet must act on the principle of being robust, will accept addresses that do not conform standards, but are otherwise understandable.
