# Endpoints and Domain Names

Endpoint: OBS provides an endpoint for each region. An endpoint is a domain name to access OBS in a region and is used to process access requests of that region. For details about regions and endpoints, see Regions and Endpoints.

Bucket domain name: Each bucket in OBS has a domain name. A domain name is the address of a bucket and can be used to access the bucket over the Internet. It is applicable to cloud application development and data sharing.

An OBS bucket domain name is in the format of BucketName.Endpoint, where BucketName indicates the name of the bucket, and Endpoint indicates the domain name of the region where the bucket is located.

Table 1 lists the bucket domain name and other domain names in OBS, including their formats and protocols.

Object domain name

BucketName.Endpoint/ObjectName

After an object is uploaded to a bucket, you can use the object domain name to access the object. You can spell out the domain name according to the structure of object domain names, or you can obtain it from the object details on OBS Console or OBS Browser. Alternatively, you can call the GetObjectUrl API through the SDK to obtain the object domain name.
