# Sources

> Schema for source citations returned by the Microsoft Copilot endpoint, listing URLs, titles, snippets, and publishers referenced in the generated answer.

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

## Example request

```json theme={null}
{
  "prompt": "best laptops for programming",
  "country": "US"
}
```

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

## Overview

Copilot sources follow the [common sources structure](/guides/making-requests/sync#sources-array-structure) (`position`, `url`, `label`, and `description`) with no Copilot-specific fields.

<Note>
  Approximately 10% of prompts genuinely don't trigger Copilot to return citations — even after internal retries. If `result.sources` is empty, it means Copilot chose not to cite sources for that prompt, not that extraction failed. Build your pipeline to handle `sources: []` as a valid response.
