Fully transparent and elastic access

First, you will want to experiment with our Free Trial API: it allows you to perform all operations in the same
quality as our paying services, but with a limited throughput.

Once you want to move to a production system, the switch to an Amazon or Azure Cloud Instance is as easy as
switching API key and host. Using one of the major cloud platforms offers a wide range of benefits:
flexible pricing (per hour basis), easy SDK integration, load balancing: see more details in the table below.

The API can be accessed via HTTP requests in JSON format or through our various Client SDKs, currently available
for Java, Python, PHP
and Android.
