# Sources

> Schema for source citations extracted from ChatGPT responses, including URLs, titles, snippets, publication dates, and footnote indicators.

This section documents the **sources** data returned by the [ChatGPT endpoint](/api-reference/endpoint/monitor-chatgpt). Sources are part of the ChatGPT response, so no separate API call is needed.

## Example request

```json theme={null}
{
  "prompt": "What are the best AI recruiting tools?",
  "model": "CHATGPT",
  "country": "US"
}
```

This produces a response containing the `sources` array documented below.

## Overview

Sources are references extracted from ChatGPT's sources modal. They follow the [common sources structure](/guides/making-requests/sync#sources-array-structure) with additional ChatGPT-specific fields.

## ChatGPT-specific source fields

| Field           | Type    | Description                                                                                                                       |
| --------------- | ------- | --------------------------------------------------------------------------------------------------------------------------------- |
| `footnote`      | boolean | Whether this source appears as a footnote (in a subsequent list in the sources modal)                                             |
| `datePublished` | string  | The publication date of the source (e.g., "May 22, 2025"). Omitted when the source has no publish date — never emitted as `null`. |

  **ChatGPT doesn't provide sources for certain prompts**

  When web search is triggered but no sources are available, the `sources` field will return an empty array.
