JSON Patch Audit

Name: JSON Patch Audit
Price: 0.15 USDC
Availability: OutOfStock

Judge an RFC 6902 patch against the document it will be applied to. The patch is applied to a copy as a sequence, so each operation is judged against the state it will actually see rather than against the original: a later operation targeting a path an earlier one removed is the defect class this exists for. Reports a missing target, which makes the whole patch fail; a remove, which has no inverse; a replace that changes type; a move into itself; and a path the caller marked protected.

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Using Roundhouse, look up the x402 service JSON Patch Audit and tell me whether it is
worth paying: what a call costs, whether the endpoint answered when last probed, and what
its payment record actually shows.

curl -s 'https://api.roundhouseai.io/v0/endpoints?q=JSON%20Patch%20Audit'
curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>'

Then call it: read the price from the live 402 at https://api.zfinia.com/x402/v1/json-patch-safety-audit, never from
a cached figure, and pay with an x402 client.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
