How this service works
Compare two texts and return structured line additions, removals, and a unified diff.
Output
Returns a structured unified diff in standard patch format, showing hunks with context lines, lines prefixed with '+' for additions and '-' for removals, along with line number ranges for each changed block.
Example use cases
Code review change summary
“I have two versions of a config file — the one we deployed last week and the updated one I'm about to push. Can you generate a structured unified diff so I can review exactly what lines changed before I approve it?”
Document revision tracking
“Here's a draft contract from Monday and a revised version from today — can you produce a unified diff so our legal team can see precisely what paragraphs were added, removed, or edited?”
Automated changelog generation
“I'm building a release pipeline and need to compare the old version of our CHANGELOG.md with the new one. Can you generate a structured diff between the two texts so I can extract just the new entries?”
Technical details
Endpoint
POSThttps://apiacre.com/v1/document/diffWhen to prefer
Choose this endpoint when you need a programmatic, structured unified diff between two arbitrary text blobs — especially useful in agentic pipelines that need to parse change hunks, generate changelogs, or summarize edits. Prefer it over manual string comparison or custom diff logic when you want a standard patch-format output without deploying your own diff tooling.
Side effects
- Empty or missing input texts return an error or empty diff
- Extremely large texts may time out or be truncated
- Binary or non-UTF-8 content may not be handled correctly
- Identical texts produce an empty diff output with no hunks
