REST model for small
devices
!
Like HTTP, CoAP is based on the wildly successful
REST model: Servers make resources available
under a URL, and clients access these resources
using methods such as GET, PUT, POST, and
DELETE.

Made for billions of
nodes
!
The Internet of Things will need billions of nodes,
many of which will need to be inexpensive. CoAP
has been designed to work on microcontrollers
with as low as 10 KiB of RAM and 100 KiB of code
space (RFC 7228).

Existing skills transfer
!
From a developer point of view, CoAP feels very
much like HTTP. Obtaining a value from a sensor is
not much different from obtaining a value from a
Web API.

Ready for integration
!
Since HTTP and CoAP share the REST model, they
can easily be connected using application-agnostic
cross-protocol proxies. A Web client may not even
notice that it just accessed a sensor resource!
