How this service works
Deep-merge an ordered list of JSON documents, left to right. Objects are merged key-by-key; arrays, scalars and null in a later document replace the earlier value (last-wins, no array concatenation).
Output
A single merged JSON document combining all input documents, where later documents in the array override earlier ones for any conflicting keys (last-write-wins semantics for deep merge)
Example use cases
Override defaults with user settings
“I have a default app config and a user-specific config — merge them so the user settings win. Defaults: {"debug": false, "timeout": 30, "locale": "en-US"}, user config: {"debug": true, "locale": "fr-FR"}.”
Combine multi-source API responses
“I got partial profile data from two different API calls and need them merged into one object. First response: {"id": 42, "name": "Alice"}, second response: {"email": "alice@example.com", "name": "Alice Smith"} — merge them with the second taking precedence.”
Layer environment-specific config overrides
“Merge my three environment configs in order — base, staging, then prod overrides — so prod values win: base is {"logLevel": "info", "maxRetries": 3, "region": "us-east"}, staging adds {"logLevel": "debug"}, and prod sets {"logLevel": "warn", "maxRetries": 5}.”
Technical details
Endpoint
POSThttps://data.openverbs.com/v1/mergeWhen to prefer
Use this endpoint when you need a reliable, hosted deep-merge of JSON documents with clear precedence ordering and don't want to implement custom merge logic yourself. It is especially useful for layered configuration management (defaults → environment → user overrides) or combining partial API responses. Prefer it over custom in-code merge when working in an agent pipeline where an external stateless call is safer than executing arbitrary merge code.
Side effects
- Fewer than 2 documents provided — API requires minItems: 2 in the documents array
- Invalid or non-JSON values passed as documents — items must be valid JSON values
- Malformed request body — bodyType must be 'json', 'form-data', or 'text'
- Network or payment failure (x402 protocol) — insufficient USDC balance or payment not accepted
