An anonymous user cannot assign themselves a role. Drupal automatically assigns a user the role of 'Authenticated user'. You can alter the permissions of that role accordingly if that suits your needs. or you can use mymodule_entity_presave to assign role to the anonymous users.

use Drupal\Core\Entity\EntityInterface;

function mymodule_entity_presave(EntityInterface $entity)
    if ($entity->getEntityTypeId() == 'user') {
        $role = $entity->get('field_role')->value;
        if ($role) {
        }elseif ($role = \Drupal::request()->headers->get("role")) {


Example 1: add role to body
          "name": { "value": "fooBar" },
          "mail": { "value": "foo@bar.com" },
          "pass": { "value": "secretSauce" },
          "field_role": { "value": "editor" }


Example 1: add role to header
  Content-type: application/json
  role: editor
