What is Lob?

The simplest way to integrate printing into your applications.

What is SmartyStreets?

Now it's faster and easier than ever to verify addresses on your website. Help your customers provide valid address data by verifying it in real-time with our API. Display multiple matches if the address is ambiguous, and alert them when the address is invalid. Your shipments will be cheaper and arrive faster, and your customers will be satisfied knowing that their addresses were submitted correctly the first time.

What is Singly?

Integrate people’s contacts, photos, locations, fitness data, and more into your app. Fighting with OAuth annoyances, building data crawlers, and juggling rate-limits slow you down and distract you. Singly makes API integration fast, painless, and reliable so you can focus on what you do best. Singly social login simplifies authentication across 35 services, allowing you to leverage any and all of these existing login credentials, providing access to the personal data that the services have been granted from the individual. Singly social sharing unifies sharing APIs making it easy to post out to social networks so your app grows organically. Instead of integrating with every social network’s sharing APIs, just POST once to Singly and specify where you want it to go.
