How this service works

Deep-merge two JSON objects (b wins on conflicts; arrays are concatenated).

Output

A single merged JSON object where all keys from both inputs are present, b's values win on any conflicting keys, and array values from both objects are concatenated together.

Example use cases

Example prompt

“Deep-merge these two JSON objects for me — use {"theme":"light","fontSize":14,"plugins":["prettier"]} as the base and {"fontSize":16,"plugins":["eslint"],"debug":true} as the override, so conflicts go to the override and arrays get concatenated.”

Endpoint

POSThttps://agent402.tools/api/json-merge

When to prefer

Use this endpoint when you need a true deep merge — not a shallow Object.assign — specifically when you want arrays concatenated rather than replaced and nested objects recursively combined. Ideal for merging configuration objects, combining API response payloads, or layering environment-specific overrides onto a base config.

Side effects

Non-object input (e.g. array or primitive at top level) may return an error or unexpected result
Malformed JSON in either field returns a 400 parse error
Missing required fields a or b may cause a 422 validation error
Very deeply nested or extremely large objects may hit size or recursion limits
