How this service works
Zach Riehn's lab: an about-me and portfolio, a news desk, The Atelier for AI experiments, Launch Lab for XRP research, and Fracture for games.
Output
Returns a JSON object with: a boolean 'identical' flag, a float 'similarity' score between 0 and 1, integer counts for 'lines_added' and 'lines_removed', and a 'unified_diff' string showing the standard unified diff format between the two inputs.
Example use cases
Version string comparison for release notes
“Compare these two version strings: A is '1.4.2' and B is '1.5.0' — give me the similarity score and a unified diff so I can see exactly what changed.”
Config file snippet drift detection
“I have two config snippets I need to diff: A is 'timeout=30
retries=3' and B is 'timeout=60
retries=3
debug=true' — how similar are they and what lines were added or removed?”
Checking if two text blocks are identical
“Are these two paragraphs identical? A is 'Hello world, this is a test.' and B is 'Hello world, this is a test.' — run a diff and tell me the similarity score.”
Technical details
Endpoint
GEThttps://cocoeatsai.com/area4/agent/tools/text-diff?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.001) programmatic text diff with a similarity score returned as structured JSON — especially useful in agent workflows comparing version strings, config snippets, or short text blocks where a unified diff and numeric similarity are both needed in one call.
Side effects
- Missing required query params 'a' or 'b' — likely returns an error or empty result
- Very large strings may cause performance degradation or timeouts
- Non-UTF8 or binary input strings may produce unexpected diff output
- Payment not completed (x402) results in 402 response before diff is computed
