HALOWERK medienwerk – Word/CSV Export Snapshot Compare

Choose this endpoint when you need a structured, downloadable export (Word or CSV) of differences between two document snapshots — ideal for creating shareable redline documents, audit trails, or tabular change logs. Prefer this over plain text comparison endpoints when the output must be formatted for human consumption in office tools or spreadsheets.

• Unsupported document format returns an error indicating the file type cannot be processed
• URL fetch failure if document URLs are inaccessible, private, or exceed size limits
• Invalid base64 encoding causes a parsing error
• Both inputs identical returns an empty diff or minimal change report
• Payment not settled via x402 results in a 402 Payment Required response
