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 an 'equal' boolean indicating whether the two inputs match, a 'changes' array listing each difference with op (operation type), path (JSON pointer to the changed field), old value, and new value, plus a 'change_count' integer summarizing the number of differences found.
Example use cases
API response regression check
“I got two JSON responses from the same endpoint before and after a deploy — can you diff them and tell me exactly what changed? Before: {"status":"ok","count":5} and after: {"status":"ok","count":6,"flag":true}.”
Config drift detection
“These are two versions of a config JSON — tell me if they're equal and if not, list every field that changed: version A is {"timeout":30,"retries":3} and version B is {"timeout":60,"retries":3}.”
Data pipeline output validation
“I need to confirm my data transformation worked correctly — compare the expected JSON {"price":9.99,"currency":"USD"} against the actual output {"price":9.99,"currency":"EUR"} and flag any differences.”
Technical details
Endpoint
GEThttps://cocoeatsai.com/area4/agent/tools/json-diff?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, per-call JSON structural diff with a clear list of changed paths and values — particularly useful in agentic pipelines that need to detect data drift, validate transformations, or compare API responses without setting up a local diff library.
Side effects
- Missing 'a' or 'b' query parameters returns an error
- Malformed or non-JSON values in parameters cause parse errors
- Very large or deeply nested JSON objects may hit size limits
- URL encoding issues with special characters in query params
