UOS Genesis Machine – Canonicalize JSON
x402
UOS Genesis Machine – Canonicalize JSON is a paid API for AI agents from genesis.palsus2023.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).
Transforms a JSON object into a deterministically ordered, canonicalized string with recursively sorted keys, suitable for hashing, signing, and deduplication.

How this service works
Autonomous paid machine utilities using x402 and Base USDC.
Output
Returns a JSON response containing a 'result' field with the canonicalized, recursively key-sorted JSON string, a 'service' field confirming 'canonicalize_json', and a 'success' boolean indicating whether the operation succeeded.
Example use cases
Stable hash key for caching
“I need to generate a stable cache key from this JSON config object — can you canonicalize it so the key order doesn't affect the hash? Here's the object: {"region": "us-east", "tier": "pro", "flags": {"verbose": true, "retry": 3}}.”
Pre-signing JSON normalization
“Before I sign this API payload with my private key, I need it in a canonical form with all nested keys sorted alphabetically so the signature is reproducible — please canonicalize: {"user": "alice", "action": "transfer", "meta": {"timestamp": 1700000000, "nonce": "abc"}}.”
Deduplication of JSON records
“I'm getting duplicate JSON records that are identical in content but have keys in different orders — can you canonicalize this one so I can compare it against a normalized dataset? Object: {"score": 99, "id": "x7", "tags": {"env": "prod", "app": "billing"}}.”
Technical details
Endpoint
POSThttps://genesis.palsus2023.workers.dev/v1/canonicalize_json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a guaranteed deterministic, recursively sorted JSON serialization — especially for cryptographic signing, stable hashing, cache key generation, or deduplication workflows where key ordering must be consistent across different producers. It is purpose-built for machine-to-machine canonical JSON scenarios at very low cost ($0.001 USDC) and operates on the x402 micropayment protocol.
Side effects
- Malformed or non-parseable JSON input returns an error with success: false
- Missing required 'input' string field causes a validation error
- Payment not provided or insufficient USDC triggers an x402 payment-required response
- Network timeout on the Cloudflare Worker edge node
