Overview

This node sends a user-provided prompt to a GPT-based API endpoint and returns the generated response. It is useful for integrating GPT-powered conversational AI or text generation capabilities into workflows, such as generating text completions, answering questions, or creating content based on user input.

Use Case Examples

1. A user inputs a prompt asking for a summary of a document, and the node returns the summarized text.
2. A user provides a question, and the node returns an answer generated by the GPT model.

Properties

Output

JSON

• response - The JSON response from the GPT API containing the generated text or answer based on the user's prompt.

Dependencies

• Requires an API key stored in the environment variable `UNEXO_API_KEY` for authorization.
• Requires the base URL of the GPT API stored in the environment variable `CDP_URL`.
• Makes HTTP POST requests to the endpoint `${CDP_URL}/api/gpt/askGPT` with the user prompt in the request body.

Troubleshooting

• Common issues include missing or invalid API key (`UNEXO_API_KEY`), resulting in authorization errors.
• Network or endpoint unavailability may cause request failures; the node retries the request up to 3 times with a 2-second delay between attempts.
• If the environment variable `CDP_URL` is not set or incorrect, the node will fail to reach the API endpoint.
