Telnyx Ai Inference - curl

Installation

text

# curl is pre-installed on macOS, Linux, and Windows 10+

Setup

bash

export TELNYX_API_KEY="YOUR_API_KEY_HERE"

All examples below use

$TELNYX_API_KEY

for authentication.

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:

bash

# Check HTTP status code in response
response=$(curl -s -w "\n%{http_code}" \
  -X POST "https://api.telnyx.com/v2/messages" \
  -H "Authorization: Bearer $TELNYX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"to": "+13125550001", "from": "+13125550002", "text": "Hello"}')

http_code=$(echo "$response" | tail -1)
body=$(echo "$response" | sed '$d')

case $http_code in
  2*) echo "Success: $body" ;;
  422) echo "Validation error — check required fields and formats" ;;
  429) echo "Rate limited — retry after delay"; sleep 1 ;;
  401) echo "Authentication failed — check TELNYX_API_KEY" ;;
  *)   echo "Error $http_code: $body" ;;
esac

Common error codes:

invalid API key,

insufficient permissions,

resource not found,

validation error (check field formats),

rate limited (retry with exponential backoff).

Important Notes

Pagination: List endpoints return paginated results. Use
```
page[number]
```
and
```
page[size]
```
query parameters to navigate pages. Check
```
meta.total_pages
```
in the response.
