# Sources

> Schema for source citations returned by the Google Gemini endpoint, including URLs, titles, snippets, and contextual descriptions for each reference.

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

## Overview

Gemini sources follow the [common sources structure](/guides/making-requests/sync#sources-array-structure) (`position`, `url`, `label`, `description`).

<Warning>
  **About sources availability**

  Gemini may not return sources for certain prompts. The sources array will be empty when Gemini doesn't provide citations. This is normal behavior and doesn't indicate an error. Some prompts don't trigger Gemini's source-citing mechanism.
</Warning>

## Example request

```json theme={null}
{
  "prompt": "Explain quantum entanglement",
  "country": "US"
}
```

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

## Example response

```json theme={null}
{
  "success": true,
  "result": {
    "text": "Quantum entanglement is a physical phenomenon...",
    "sources": [
      {
        "position": 1,
        "label": "Wikipedia",
        "url": "https://en.wikipedia.org/wiki/Quantum_entanglement",
        "description": "Quantum entanglement is a physical phenomenon that occurs..."
      }
    ]
  }
}
```
