This section documents the sources data returned by the Microsoft Copilot endpoint. Sources are part of the Copilot response, so no separate API call is needed.

​
Example request

{
  "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 (position, url, label, and description) with no Copilot-specific fields.
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.
