Telnyx AI Assistants Curl

Telnyx AI Assistants - curl

Installation

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

Setup

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:

curl \
  -X POST \
  -H "Authorization: Bearer $TELNYX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
      "name": "my-resource",
      "instructions": "You are a helpful assistant.",
      "model": "openai/gpt-4o"
  }' \
  "https://api.telnyx.com/v2/ai/assistants"

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

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

Create an assistant

Assistant creation is the entrypoint for any AI assistant integration. Agents need the exact creation method and the top-level fields returned by the SDK.

POST /ai/assistants

curl \
  -X POST \
  -H "Authorization: Bearer $TELNYX_API_KEY" \
  -H "Content-Type: application/json" \

      "instructions": "You are a helpful assistant.",
      "model": "openai/gpt-4o"
  }' \
  "https://api.telnyx.com/v2/ai/assistants"

Primary response fields:

• .data.id
• .data.name
• .data.model
• .data.instructions

Chat with an assistant

Chat is the primary runtime path. Agents need the exact assistant method and the response content field.

  -H "Content-Type: application/json" \

    },
    {
      "criteria": "Provides correct product information",
      "name": "Accuracy"
    }
  ]
}' \
