  Create an identity — an end user or organisation that keys and shared rate limits attach to. Unkey: POST /v2/identities.createIdentity.
• unkey_create_key Changes accounts · ~426 tokens

• unkey_delete_key Deletes data · ~143 tokens
  Revoke a key. By default this is a soft delete the key stops working but stays queryable; pass permanent to erase it. Unkey: POST /v2/keys.deleteKey.

• unkey_get_key ~159 tokens
  Fetch a key's metadata by its key id — name, owner, permissions, credits, rate limits and whether it is enabled. Read-only despite being a POST. Unkey: POST /v2/keys.getKey.
• unkey_get_ratelimit_override ~140 tokens
  Fetch the override for one identifier in a namespace. Read-only despite being a POST. Unkey: POST /v2/ratelimit.getOverride.
• unkey_list_api_keys ~197 tokens

• unkey_list_identities ~164 tokens
  List identities — the end users or organisations your keys belong to. Read-only despite being a POST. Unkey: POST /v2/identities.listIdentities.
• unkey_list_permissions ~154 tokens
  List the permissions defined in the workspace. Read-only despite being a POST. Unkey: POST /v2/permissions.listPermissions.
• unkey_list_ratelimit_overrides ~171 tokens

The query must use one of the public aliases: key_verifications_v1, key_verifications_per_minute_v1, key_verifications_per_hour_v1, key_verifications_per_day_v1 or key_verifications_per_month_v1. Physical default.* table names are rejected,
