How this service works
Compare two JSON documents - every added, removed, changed or retyped path with old and new values, plus a summary count by operation
Output
Returns a JSON object with: an `identical` boolean, a `changes` count, a `diff` array where each entry has a JSONPath, operation type (added/removed/changed/retyped), and from/to values, a `by_op` summary with counts per operation type, and optional `note` and `truncated` flags if the result was cut off.
Example use cases
API response regression check
“I have two versions of an API response — the one from yesterday and today's — can you compare them and tell me every field that changed, was added, or disappeared, with the old and new values?”
Config file change audit
“Before I deploy, compare these two JSON config files and list every difference by JSONPath so I can audit what changed: here's the old config and here's the new one.”
Database record snapshot diff
“I saved a JSON snapshot of a user record before and after an update — can you diff them and give me a count of how many fields were added, changed, or removed?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/json/diff?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, machine-readable JSON diff with explicit JSONPaths, operation types, and old/new values — especially when you want a summary count by operation type. Prefer it over generic text-based diff tools when downstream code needs to process the differences programmatically. Best suited for JSON documents under 6000 characters each.
Side effects
- Missing required query parameters `a` or `b` returns an error
- Input JSON string exceeds 6000 character limit and is rejected
- Malformed JSON in either parameter causes a parse error
- Very large or deeply nested documents may hit the truncation limit, indicated by `truncated: true` in the response
- Network or service unavailability returns a non-200 status
