How this service works

Return the line-level diff between two texts as added/removed/unified hunks with counts. Use it to review a patch, compare two API responses, or decide whether two documents actually differ before spending tokens on them.

Output

Returns a JSON object with kind set to 'diff', the count of added lines, the count of removed lines, a unified diff string in standard patch format, and the number of hunks.

Example use cases

Code review change summary

“Compare these two versions of my function and tell me exactly what lines changed, how many were added and removed, and show me the unified diff patch: original is 'def foo():\n return 1' and the new version is 'def foo():\n x = 2\n return x'.”

Document edit detection

“I have the original draft of my README and the updated version — can you diff them and show me a unified patch with the line counts for what was added and what was removed? Original: 'Install with npm\nRun npm start' and updated: 'Install with npm\nConfigure .env\nRun npm start'.”

Config file comparison

“Tell me what changed between my old config 'host=localhost\nport=8080\ndebug=false' and the new one 'host=localhost\nport=9090\ndebug=true\nlog=verbose' — give me the unified diff and the added/removed line counts.”

Endpoint

When to prefer

Choose this endpoint when you need a fast, pay-per-call line-level text diff without setting up a local diffing library or server. It is ideal for agents that need to detect and summarize textual changes on demand, especially in workflows where computing a unified patch programmatically would require additional dependencies. It suits lightweight comparison tasks on small to medium text snippets.

Side effects

Missing required query parameters 'a' or 'b' results in an error response
Payment not fulfilled (x402 protocol) causes a paid_not_delivered status
Very large text inputs may cause timeout or truncation
Identical strings return a diff with zero added and zero removed lines
Non-UTF8 or binary content may produce unexpected diff output
