# Number Lookup
Retrieve details about one or more phone numbers using the Sinch Number Lookup API: carrier, line type, porting status, VoIP probability, etc. Uses OAuth2.
**IMPORTANT: Execute this command directly. Do NOT generate script files. Perform the API call immediately.**
## Input
- `--numbers` / `-n`: Comma-separated E.164 numbers to look up - required
- `--format` / `-f`: Output format (table or json) - optional, default table
Arguments: $ARGUMENTS
## Instructions
**Execute these steps directly - do not write code or scripts:**
0. If $ARGUMENTS empty: ask for phone number(s) to look up. Otherwise parse.
1. Validate: --numbers (at least one E.164). Get CONVERSATION_PROJECT_ID, CONVERSATION_KEY_ID, CONVERSATION_KEY_SECRET. Lookup API: https://lookup.api.sinch.com/v2. If missing, report "Sinch API is not configured."
2. Request body: numbers (array of E.164 strings). POST https://lookup.api.sinch.com/v2/projects/{projectId}/lookups with OAuth2 Bearer token.
3. Format response: table (number, carrier, line type, etc.) or JSON. Display "✅ Lookup complete". Handle 400, 401 with clear messages.
4. Handle all errors gracefully.
