Preview file from citation.

Purpose

This endpoint lets you Preview file from citation for indexed pages/documents inside an agent’s knowledge base.

This endpoint also doubles as your ingestion debugger: by inspecting page records and crawl/index statuses, you can work out what content is actually searchable by the agent at any given time.

At a high level, this is the canonical way to work with indexed pages/documents inside an agent’s knowledge base via the CustomGPT API.

When to use

• When you need to preview file from citation as part of your backend or automation workflows.
• To debug ingestion by checking which URLs or files have actually been crawled and indexed, and in what state.
