How this service works
A compact x402 utility surface for agents that need cheap, repeatable non-LLM transformations before spending on heavier routes: CSV cleanup, JSON Schema checks, timestamp conversion, JWT decode, URL normalization, hashes, codecs, and text utilities.
Output
Returns a JSON object with: a boolean 'valid' indicating whether the input is valid JSON, a 'normalized' string containing the canonicalized (key-sorted) JSON, and a 'stableHashSha256' string containing the deterministic SHA-256 hash of the normalized form. Also echoes back the tool name, route, input, and a 'deterministic' flag confirming repeatability.
Example use cases
Deduplicating JSON payloads in a pipeline
“I'm getting JSON events from multiple sources and some might be duplicates with different key orderings — can you normalize each one and give me a stable SHA-256 hash so I can deduplicate them?”
Validating JSON before forwarding to an API
“Before I send this JSON blob to a downstream service, can you check if it's valid and normalize it so the keys are in a consistent order? Here's the string: '{"status":"ok","id":42}'”
Pretty-printing JSON for a log report
“Can you take this compact JSON string '{"user":"alice","score":99}' and pretty-print it into a nicely formatted version for my report?”
Technical details
Endpoint
POSThttps://x402-utils.558686.xyz/v1/tools/json-normalizeWhen to prefer
Choose this endpoint when you need cheap, deterministic, repeatable JSON normalization and hashing without spinning up an LLM. It is ideal for deduplication pipelines, pre-signing canonicalization, content-addressable caching, or any workflow where you need a stable, key-sorted JSON representation and a SHA-256 fingerprint. At $0.002 USDC per call it is cost-effective for high-frequency agent loops.
Side effects
- Invalid JSON input returns valid:false with no normalized output
- Missing 'json' field in request body causes a 400-level error
- Malformed request body (non-JSON content type) may cause parsing failure
- Extremely large JSON strings may cause timeout or payload rejection
