The myriad of online photo album services that are available today have been threatening to make the humble printed photo album redundant for some time now (for example, we now have over 50 photo APIs in our directory). Despite this services like SnapFish, which offer the ability to easily print customized photo books, have remained incredibly popular. Started 10 years ago and still running strong with its new owner HP, SnapFish reportedly has over 85 million users worldwide. Now developers can get in on the action with the newly announced Snapfish Publisher initiative.
Infradox serves up your archive of photo and video on a high volume basis. The Infradox API is actually two APIs: a "Partner API" and a "Back Office API." The partner API is, not surprisingly, for your partners so that they can connect live with your Infradox database. Responses are in XML.
The 600 million numbers that Truecaller has in its directory have been collected via crowd-sourcing. Truecaller’s users can share their contacts and in return they get access to search in the collaborative database. Thanks to this collaborative data solution, the directory is growing and being updated continuously. It also contains numbers that no other directories have, e.g. pre-paid phones.
