project_id	Yes	String	Specifies the project ID.

Request

Table 2 describes the request parameters.

**Table 2** Request parameters
Parameter	Mandatory	Type	Description
tags	No	Array<Object>	Specifies the included tags. Each tag contains a maximum of 10 keys, and each key contains a maximum of 10 values. The structure body cannot be missing, and the key cannot be left blank or set to an empty string. Each tag key must be unique, and each tag value in a tag must be unique. Resources identified by different keys are in AND relationship, and values in one tag are in OR relationship. If no tag filtering criteria is specified, full data is returned.
tags_any	No	Array<Object>	Specifies any included tags. Each tag contains a maximum of 10 keys, and each key contains a maximum of 10 values. The structure body cannot be missing, and the key cannot be left blank or set to an empty string. Each tag key must be unique, and each tag value in a tag must be unique. Resources identified by different keys are in OR relationship, and values in one tag are in OR relationship. If no tag filtering criteria is specified, full data is returned.
not_tags	No	Array<Object>	Specifies the excluded tags. Each tag contains a maximum of 10 keys, and each key contains a maximum of 10 values. The structure body cannot be missing, and the key cannot be left blank or set to an empty string. Each tag key must be unique, and each tag value in a tag must be unique. Resources not identified by different keys are in AND relationship, and values in one tag are in OR relationship. If no tag filtering criteria is specified, full data is returned.
not_tags_any	No	Array<Object>	Specifies any excluded tags. Each tag contains a maximum of 10 keys, and each key contains a maximum of 10 values. The structure body cannot be missing, and the key cannot be left blank or set to an empty string. Each tag key must be unique, and each tag value in a tag must be unique. Resources not identified by different keys are in OR relationship, and values in one tag are in OR relationship. If no tag filtering criteria is specified, full data is returned.
limit	No	String	Number of records. This parameter is not available when action is set to count. The default value is 1000 when action is set to filter. The maximum value is 1000, and the minimum value is 1. The value cannot be a negative number.
offset	No	String	Specifies the index position. The query starts from the next piece of data indexed by this parameter. This parameter is not required when you query data on the first page. The value in the response returned for querying data on the previous page will be included in this parameter for querying data on subsequent pages. This parameter is not available when action is set to count. If action is set to filter, the value must be a number, and the default value is 0. The value cannot be a negative number.
action	Yes	String	Specifies the operation to perform, which can only be filter (filtering) or count (querying the total number). The value filter indicates pagination query. Value count indicates that the total number of query results meeting the search criteria will be returned. Returning other fields is not allowed.
matches	No	Array<match>	Specifies the search criteria. The tag key is the field to match, for example, resource_name. The tag value indicates the matched value. This field is a fixed dictionary value. Determine whether fuzzy match is required based on different fields. For example, if key is resource_name, fuzzy search (case insensitive) is used by default. If value is an empty string, exact match is used. If key is resource_id, exact match is used.

**Table 3** Parameter description of field **tag**
Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the tag key. It can contain a maximum of 127 Unicode characters. key cannot be left blank, be an empty string, or be spaces. Before using key, delete spaces before and after the value.
values	Yes	Array<String>	Specifies the tag values. Each value contains a maximum of 255 Unicode characters and cannot contain spaces. Before verification, delete spaces before and after the value. The asterisk () is a reserved character. The value can be empty but cannot be left blank. If the value starts with an asterisk (), the string following the asterisk is fuzzy matched. If the values are null, it indicates any_value (querying any value). The values are in OR relationship.

**Table 4** Description of field **match**
Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the tag key. The value is fixed at resource_name.
value	Yes	String	Specifies the key value. It can contain a maximum of 255 Unicode characters.

Response

Table 5 describes the response parameters.

**Table 5** Response parameter
Parameter	Type	Description
resources	Array<resource>	Specifies the resource object list. For details, see Table 6.
total_count	Integer	Specifies the total number of resources.

**Table 6** Data structure description of field **resource**
Parameter	Type	Description
resource_id	String	Specifies the resource ID.
resource_detail	Object	Provides details about the resource. The value is a resource object, used for extension. This parameter is left blank by default.
tags	Array<resource_tag>	Specifies the list of queried tags. If no tag is matched, an empty array is returned. For details, see Table 7.
resource_name	String	Specifies the resource name. This parameter is an empty string by default if there is no resource name.

**Table 7** Parameter description of field **resource_tag**
Parameter	Type	Description
key	String	Specifies the tag key. It contains a maximum of 36 Unicode characters. A tag key cannot be left blank. It cannot contain non-printable ASCII characters (0–31) or the following special characters: *<>\=
value	String	Specifies the key value. The value can contain a maximum of 43 Unicode characters and can be an empty string. It cannot contain ASCII characters (0–31) and the following characters: *<>\=
