How this service works
Unified diff between two texts, plus added/removed line counts and a similarity ratio.
Output
Returns a unified diff string showing line-level changes between the two input texts, a count of added lines, a count of removed lines, and a floating-point similarity ratio (0–1) indicating how alike the two texts are.
Example use cases
Code review change summary
“I have two versions of a Python function — the original and the one my teammate edited. Can you diff them and tell me exactly what lines changed, how many lines were added or removed, and give me a similarity score?”
Document revision tracking
“Compare these two drafts of my blog post introduction and show me a unified diff with the line-level changes, plus tell me the similarity ratio so I know how much it changed.”
Automated config change detection
“I need to diff my old nginx config against the new one and get back a unified diff along with counts of added and removed lines — can you do that for me?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/text-diffWhen to prefer
Choose this endpoint when you need a structured, machine-readable diff with similarity scoring between two arbitrary text strings — particularly when you need both the unified diff format and quantitative change metrics (line counts + ratio) in a single call, without setting up a local diff library.
Side effects
- Missing or empty input texts return a 400 error
- Extremely large texts may time out or be rejected
- Non-UTF-8 encoded content may cause parsing errors
- Both texts identical returns zero diff with similarity ratio of 1.0
