Overview

Welcome to Content Delivery Network API Reference. Content Delivery Network (CDN) is an intelligent virtual network built on top of existing Internet infrastructure. Origin content is cached on nodes closer to end users so content can load faster. CDN speeds up site response and improves site availability, breaking through the bottlenecks caused by low bandwidth, heavy user access traffic, and uneven distribution of edge nodes.

This document describes how to use application programming interfaces (APIs) to perform operations on CDN, such as creating, deleting, and modifying an accelerated domain name.

If you plan to access CDN through an API, ensure that you are familiar with CDN concepts. For details, see Service Overview.
