# 10DLC Brand Registrations

List or create 10DLC (US A2P SMS) brand registrations using the Sinch 10DLC API. Brands must be registered before creating campaigns. Uses OAuth2. Base: https://us10dlc.api.sinch.com/v1.

**IMPORTANT: Execute this command directly. Do NOT generate script files. Perform the API call immediately.**

## Input

- `--action` / `-a`: list or create - optional, default list
- `--display-name` / `-n`: Brand display name (for create) - required if action=create
- `--entity-type` / `-e`: Entity type (PRIVATE, PUBLIC, etc.) - optional for create
- `--format` / `-f`: Output format (table or json) - optional

Arguments: $ARGUMENTS

## Instructions

**Execute these steps directly - do not write code or scripts:**

0. If $ARGUMENTS empty: ask "List brands or create a new brand?" and get action, or for create get display name. Otherwise parse.

1. Validate: --action (list|create), for create require --display-name. Get CONVERSATION_PROJECT_ID, CONVERSATION_KEY_ID, CONVERSATION_KEY_SECRET. If missing, report "Sinch API is not configured."

2. If list: GET https://us10dlc.api.sinch.com/v1/projects/{projectId}/brandRegistrations with OAuth2. Display table or JSON.

3. If create: POST https://us10dlc.api.sinch.com/v1/projects/{projectId}/brandRegistrations with body (displayName, entityType if needed). Return brand ID. Handle 400 (validation).

4. "✅ Brands listed" or "✅ Brand created". Handle 401, 404. Handle all errors gracefully.
