Telnyx Numbers Javascript Agent Skill

Telnyx Numbers - JavaScript

Installation

npm install [email protected]

Setup

import Telnyx from 'telnyx';

const client = new Telnyx({
  apiKey: process.env['TELNYX_API_KEY'], // This is the default and can be omitted
});

All examples below assume client is already initialized as shown above.

Error Handling

All API calls can fail with network errors, rate limits (429), validation errors (422),

or authentication errors (401). Always handle errors in production code:

try {
  const availablePhoneNumbers = await client.availablePhoneNumbers.list();
} catch (err) {
  if (err instanceof Telnyx.APIConnectionError) {
    console.error('Network error — check connectivity and retry');
  } else if (err instanceof Telnyx.RateLimitError) {
    const retryAfter = err.headers?.['retry-after'] || 1;
    await new Promise(r => setTimeout(r, retryAfter * 1000));
  } else if (err instanceof Telnyx.APIError) {
    console.error(`API error ${err.status}: ${err.message}`);
    if (err.status === 422) {
      console.error('Validation error — check required fields and formats');
    }
  }
}

Common error codes: 401 invalid API key, 403 insufficient permissions,

404 resource not found, 422 validation error (check field formats),

429 rate limited (retry with exponential backoff).

Important Notes

• Phone numbers must be in E.164 format (e.g., +13125550001). Include the + prefix and country code. No spaces, dashes, or parentheses.
• Pagination: List methods return an auto-paginating iterator. Use for await (const item of result) { ... } to iterate through all pages automatically.

Reference Use Rules

Do not invent Telnyx parameters, enums, response fields, or webhook fields.

• If the parameter, enum, or response field you need is not shown inline in this skill, read references/api-details.md before writing code.
• Before using any operation in ## Additional Operations, read the optional-parameters section and the response-schemas section.

Core Tasks

Search available phone numbers

Number search is the entrypoint for provisioning. Agents need the search method, key query filters, and the fields returned for candidate numbers.

client.availablePhoneNumbers.list() — GET /available_phone_numbers

| Parameter | Type | Required | Description |

|-----------|------|----------|-------------|

| filter | object | No | Consolidated filter parameter (deepObject style). |

console.log(availablePhoneNumbers.data);

Response wrapper:

• items: availablePhoneNumbers.data
• pagination: availablePhoneNumbers.meta

Primary item fields:

• phoneNumber
• recordType
• quickship
• reservable
