Filter resources by tag

The GET /accounts/{account_id}/tags/resources endpoint supports tag filtering via the tag query parameter. Multiple tag parameters combine with AND logic. For the full endpoint specification, refer to the Resource Tagging API reference ↗.

Filter types

Key-only filter

Match resources that have a specific tag key, regardless of value.

# All resources with an "environment" tag (any value)
curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/tags/resources?tag=environment" \
  -H "Authorization: Bearer $API_TOKEN"

Key-value filter

Match resources where a tag key has a specific value.

# All resources with environment=production
curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/tags/resources?tag=environment=production" \
  -H "Authorization: Bearer $API_TOKEN"

Multiple values (OR)

Match resources where a tag key has any of the specified values. Separate values with commas.

# environment=production OR environment=staging
curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/tags/resources?tag=environment=production,staging" \
  -H "Authorization: Bearer $API_TOKEN"

Maximum of 10 OR values per filter (error code 1013 if exceeded).

Negate key

Match resources that do not have a specific tag key.

# All resources without an "archived" tag
curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/tags/resources?tag=!archived" \
  -H "Authorization: Bearer $API_TOKEN"

Negate key-value

Match resources where a tag key does not have a specific value.

# All resources where region is NOT us-west-1
curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/tags/resources?tag=region!=us-west-1" \
  -H "Authorization: Bearer $API_TOKEN"

Combining filters

Multiple tag parameters combine with AND logic. All conditions must match.

# Production resources in US regions, excluding archived
curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/tags/resources?tag=environment=production&tag=region=us-west-1,us-east-1&tag=!archived" \
  -H "Authorization: Bearer $API_TOKEN"

Maximum of 20 tag filters per query (error code 1010 if exceeded).

Discover available tags

List all tag keys

curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/tags/keys" \
  -H "Authorization: Bearer $API_TOKEN"

List values for a key

curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/tags/values/environment" \
  -H "Authorization: Bearer $API_TOKEN"

Optionally filter by resource type:

curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/tags/values/environment?type=worker" \
  -H "Authorization: Bearer $API_TOKEN"

Pagination

All list endpoints use cursor-based pagination with a fixed page size of 100 results.

When the response includes a non-null result_info.cursor, pass it as a query parameter to get the next page:

curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/tags/resources?tag=environment=production&cursor=$CURSOR" \
  -H "Authorization: Bearer $API_TOKEN"

When cursor is null, you have reached the last page. Pagination works seamlessly with tag filters.
