How this service works
Deep-compare two JSON values. Returns a list of changed/added/removed paths (capped at 1000 differences).
Output
A list of up to 1000 difference entries, each describing a path in the JSON structure along with whether it was changed, added, or removed, enabling precise identification of structural and value-level changes between two JSON documents.
Example use cases
Example prompt
“Compare these two JSON objects and tell me every path that was added, removed, or changed: {"name":"Alice","age":30,"city":"Boston"} vs {"name":"Alice","age":31,"country":"USA"}.”
Technical details
Endpoint
POSThttps://agent402.tools/api/json-diffWhen to prefer
Choose this endpoint when you need a precise, path-level diff between two arbitrary JSON values — especially when comparing API responses, configuration snapshots, or data migration outputs. It's ideal for agents that need a structured list of changes rather than a boolean equality check, and when the two JSON documents may differ in more than one place.
Side effects
- Invalid or malformed JSON in field 'a' or 'b' results in a parse error response
- Missing 'a' or 'b' fields in the request body returns a validation error
- More than 1000 differences exist — only the first 1000 are returned, remainder silently truncated
- Payment not provided or insufficient USDC results in a 402 Payment Required response
- Extremely large or deeply nested JSON may cause timeout or memory errors
