javascriptimport 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.
All API calls can fail with network errors, rate limits (429), validation errors (422), or authentication errors (401). Always handle errors in production code:
javascripttry { const result = await client.messages.send({ to: '+13125550001', from: '+13125550002', text: 'Hello' }); } catch (err) { if (err instanceof Telnyx.APIConnectionError) { console.error('Network error — check connectivity and retry'); } else if (err instanceof Telnyx.RateLimitError) { // 429: rate limited — wait and retry with exponential backoff 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).

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 23 cases were attempted. The headline lift of +74 percentage points is the difference between those two pass rates over the 23 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
