SignalDesk AI JSON Diff
x402
SignalDesk AI JSON Diff is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).
Computes a JSON Patch (RFC 6902) diff between two JSON values, returning the sequence of add/replace/remove operations needed to transform 'before' into 'after'

How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
A JSON object with a 'patch' array containing RFC 6902 patch operation objects, each with an 'op' field (add, remove, or replace), a 'path' field (JSON Pointer string), and optionally a 'value' field for add/replace operations. The patch fully describes how to transform the 'before' JSON into the 'after' JSON.
Example use cases
Config drift detection between deployments
“I have two versions of a service config — the old one is {"timeout":30,"retries":3,"debug":true} and the new one is {"timeout":60,"retries":3}. What patch operations describe the changes?”
API response change tracking
“My API returned {"status":"pending","count":5} yesterday and today it returns {"status":"done","count":7,"result":"ok"} — can you show me exactly what changed as a JSON patch?”
Schema migration diff for feature flag update
“I need to know the diff between my old feature flags JSON {"flagA":false,"flagB":true} and the updated one {"flagA":true,"flagC":false} — give me the RFC 6902 patch operations.”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/json/diff?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call JSON diff computation without running your own server — especially useful for agents performing change detection, config audits, or migration planning where you need RFC 6902-compliant patch arrays. Prefer it over local libraries when operating in serverless or sandboxed environments without native JSON patch support.
Side effects
- Malformed or non-JSON input for 'before' or 'after' fields returns an error
- Overly large or deeply nested JSON structures may be rejected due to bounded execution limits
- Missing required fields ('before' or 'after') results in a validation error
- Payment not provided or insufficient USDC causes a 402 Payment Required response
- Cloudflare Worker cold start or quota exhaustion may cause transient 5xx errors
