Issue

Using Admin Token categories will comes in rest API but without token not working any solution on to how to get all categories without token in magento 2

Solution

By default, Magento 2 allows access without authentication for few endpoints, which are declared as anonymous resources. For example, V1/directory/currency and V1/directory/countries can be accessed without any authentication.

But, When Users need to access to non-anonymous endpoints. This option (Allow Anonymous Guest Access) must be enabled:

Stores > Settings > Configuration > Services > Magento Web API > Web API Security > Allow Anonymous Guest Access

Now, It is possible to get the categories without authentication by using this endpoint.

http://example.com/rest/V1/categories

Note: It is not recommended to use Magento 2 REST API without authentication.
