AgentResolver JSON Normalize
x402
AgentResolver JSON Normalize is a paid API for AI agents from agentresolver.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-18).
Normalizes a JSON string value and returns the canonical form along with its SHA-256 hash and byte size

How this service works
Verify an x402 endpoint before paying: live payTo, USDC quote, network, asset, resource binding, TLS and endpoint safety for $0.001 on Base or Solana.
Output
Returns an object with three fields: 'normalized' (the canonical string form of the input JSON), 'sha256' (a 64-character lowercase hex SHA-256 hash of the normalized value), and 'bytes' (an integer representing the byte length of the normalized string).
Example use cases
Deduplicate JSON records by hash
“I have a JSON record '{"id":42,"tags":["foo","bar"],"active":true}' and I want to normalize it and get its SHA-256 hash so I can check for duplicates in my database.”
Verify JSON payload integrity
“Can you take this JSON payload '{"event":"purchase","amount":99.99,"currency":"USD"}' and give me the canonical normalized form plus its SHA-256 fingerprint so I can verify it hasn't been tampered with?”
Measure normalized JSON byte size
“Normalize this JSON string '{"a":1,"b":2,"c":{"d":3}}' and tell me exactly how many bytes the normalized version is so I can check it against my size limits.”
Technical details
Endpoint
POSThttps://agentresolver.vercel.app/api/json-normalizeWhen to prefer
Use this endpoint when you need a deterministic, canonical representation of a JSON string — especially for deduplication, integrity verification, or content-addressable storage. It is well-suited when you need both the normalized form and a cryptographic hash in a single call, avoiding the need to run separate hashing and formatting steps.
Side effects
- Invalid or malformed JSON input may return an error or unexpected normalization
- Empty string input may fail validation since 'value' is required
- Very large JSON strings may time out or hit payload size limits
- Non-string input for the 'value' field will fail schema validation
