WWW::Foursquare is a wrapper for the Foursquare API written in PERL. It allows users to connect their apps with Foursquare via OAuth 2.0 authentication.
Nine APIs have been added to the ProgrammableWeb directory in categories including Internet of Things, Messaging, and Social Media. Featured today are APIs from CronAlarm, for integrating with the cron jobs platform, and from The Things Network, a crowdsourced IoT networking platform.
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.
