How this service works
Diff two JSON documents structurally. POST {a, b} returns every added, removed, and changed path with old/new values, plus an equal flag. Handles nested objects and arrays. For agents comparing API snapshots, config versions, or before/after state without writing traversal code.
Output
A structured diff object listing every path in the two JSON documents that was added, removed, or changed, with the old value and new value at each changed path, plus a top-level boolean equal flag indicating whether the documents are identical.
Example use cases
Detect API response drift
“Here are two snapshots of the /users endpoint response taken 24 hours apart — can you diff them and tell me exactly which fields changed, were added, or disappeared?”
Config version comparison
“I've got two versions of my app's config JSON — the one deployed last week and the current one. Diff them so I can see exactly what changed before I write the release notes.”
Before/after state validation
“I just ran a database migration. Here's the JSON export of a record before and after — can you compare them and confirm whether anything unexpected changed, and list every field that's different?”
Technical details
Endpoint
POSThttps://x402.shizu.me/jsondiff?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, structured JSON diff without writing custom traversal logic — especially useful for agents comparing API snapshots, config versions, or before/after state changes in a pipeline. Prefer it over text-based diff tools when you need machine-readable path-level changes with typed old/new values rather than line-by-line text output.
Side effects
- Malformed or non-JSON input for a or b returns an error
- Missing required fields a or b in request body
- Payment failure or insufficient USDC balance returns 402
- Very deeply nested or extremely large JSON documents may time out
- Arrays with reordered elements may produce verbose path-level diffs rather than semantic move detection
