How this service works
JSON Object Sort Keys: JSON Object Sort Keys returns a top-level JSON object with deterministic key order from bounded caller-supplied values without an external provider. Call JSON Object Sort Keys before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Object Sort Keys as versioned deterministic JSON. Price: $0.001 USDC…
Output
Returns the input JSON object with its top-level keys reordered in deterministic (alphabetical) order, along with metadata such as key counts, normalized values, and a versioned result contract. The response is structured deterministic JSON.
Example use cases
Stable payload before downstream tool
“Before handing this config object to the schema validator, sort its keys alphabetically so the key order is always deterministic: {"timeout": 30, "retries": 3, "endpoint": "https://api.example.com"}.”
Reproducible hash of JSON object
“I need to compute a consistent hash of this JSON object — can you sort its keys first so the order never varies between runs? The object is {"user": "alice", "role": "admin", "created": 1700000000}.”
Normalize API response keys for diff
“I'm comparing two versions of an API response and the key order keeps changing. Sort the keys of this object so I can do a clean diff: {"status": "ok", "data": null, "code": 200}.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-object-sort-keysWhen to prefer
Choose this endpoint when you need a fast, cheap, stateless, and deterministic sort of a JSON object's top-level keys — especially before passing structured data to a downstream tool with a strict key-order contract, computing a canonical hash, or performing reliable diffs. It is preferable over rolling your own sort logic when you want a versioned, auditable result contract with counts and normalization metadata.
Side effects
- Object exceeds 128 top-level properties — request rejected with validation error
- Input is not a valid JSON object (e.g. array or primitive) — type error returned
- Malformed request body — 400 bad request
- Payment not included or insufficient — 402 payment required
- Network timeout or server unavailability — 5xx error
