# List Senders (Numbers API)

Interactive code generator for the Sinch Numbers API. This command helps you generate code snippets for listing virtual phone numbers.

**IMPORTANT: Execute this command directly. Do NOT create script files. Either show an interactive menu or directly query the Numbers API based on user needs.**

## Input

No arguments required - this is an interactive command

Arguments: $ARGUMENTS

## Instructions

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

1. Present an interactive menu with the following options:
   - List all numbers
   - Filter by region code
   - Filter by type (MOBILE, LOCAL, TOLL_FREE)
   - Filter by capability (SMS, VOICE)
   - View pagination options

2. Try to call `mcp__sinch__sinch-mcp-configuration` to get the current configuration.

3. If MCP is NOT available, retrieve configuration from environment variables:
   - CONVERSATION_PROJECT_ID (or NUMBERS_PROJECT_ID)
   - CONVERSATION_KEY_ID (or NUMBERS_KEY_ID)
   - CONVERSATION_KEY_SECRET (or NUMBERS_KEY_SECRET)
   - If any are missing, report: "Sinch API is not configured. Please set the required environment variables."

4. Based on user selection, generate TypeScript code examples showing:
   - How to authenticate with Sinch Numbers API
   - How to make the API request with proper filters
   - How to handle pagination
   - How to process the response

5. Display the generated code with syntax highlighting if available.

6. Optionally, if user requests it, execute the code directly:
   - Use the Sinch Numbers API
   - Endpoint: `GET https://numbers.api.sinch.com/v1/projects/{projectId}/activeNumbers`
   - Use OAuth2 authentication with key ID and secret
   - Apply any filters from user's menu selection
   - Display results in a formatted table

7. Provide execution instructions and next steps.

## Examples

Launch the interactive generator:
```
/sinch-api-senders-list
```

## API Reference

- **MCP Tool**: `mcp__sinch__sinch-mcp-configuration` (for getting configuration)
- **API Endpoint**: `GET /v1/projects/{projectId}/activeNumbers`
- **Documentation**: https://developers.sinch.com/docs/numbers/api-reference/numbers/tag/Available-Number/

## Sample Generated Code

```typescript
import { SinchClient } from '@sinch/sdk-core';

const sinch = new SinchClient({
  projectId: 'your-project-id',
  keyId: 'your-key-id',
  keySecret: 'your-key-secret'
});

// List all active numbers with pagination
const listNumbers = async () => {
  const response = await sinch.numbers.available.list({
    regionCode: 'US',
    type: 'LOCAL',
    capabilities: ['SMS']
  });
  
  console.log('Available Numbers:', response.availableNumbers);
};
```

## Notes

- This is an educational/development tool for learning the Numbers API
- Generated code is ready to use in your Node.js/TypeScript projects
- The command provides interactive guidance for different use cases
- Numbers API requires proper authentication with project credentials
- This command uses `mcp__sinch__sinch-mcp-configuration` to retrieve your Sinch configuration
