ONE Engine Sort Keys
x402
ONE Engine Sort Keys is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0011/call, status unknown (last checked 2026-10-02).
Recursively sorts all keys in a JSON object alphabetically and returns the canonically ordered result.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object identical in content to the input but with all keys sorted alphabetically at every level of nesting. The structure and values are preserved; only key ordering changes.
Example use cases
Canonical JSON for deterministic hashing
“I need to hash this JSON payload consistently — can you sort all its keys alphabetically first so the key order doesn't affect the hash? Here's the object: {"timestamp":"2024-01-01","amount":100,"currency":"USD","metadata":{"source":"web","id":42}}”
Normalizing API response for comparison
“I'm comparing two API responses that might have the same data but different key orderings — can you sort all the keys in this JSON so I can diff them cleanly? Object: {"status":"ok","data":{"name":"Alice","age":30},"code":200}”
Preparing JSON for canonical signature
“Before I sign this JSON payload, I need all keys sorted alphabetically at every level — please sort this for me: {"user":{"role":"admin","email":"a@b.com"},"action":"delete","resource":"post"}”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/json/sort-keys?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, pay-per-call, agent-native way to canonicalize JSON key order — especially in workflows where deterministic key ordering matters for hashing, signing, or diffing. At $0.0011 USDC per call via x402 on Base, it is ideal for high-frequency agent pipelines where spinning up a local utility is impractical. Prefer it over ad-hoc sorting logic when you need a reliable, stateless microservice call.
Side effects
- Invalid or missing 'value' field in request body — endpoint may return an error or empty result
- Non-object input types (arrays, primitives) may not be sorted or may return unexpected output
- Payment failure via x402 protocol blocks the call entirely
- Deeply nested objects may have unexpected behavior if circular references exist
