## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability one-service-descriptor-json-change-auditor-e13c134c -d '<json body>'
```

Example prompt: Can you audit the changes I made to my ONe service descriptor — here's the before version and the after version — and tell me which JSON paths were added, removed, or changed, and whether any new schema violations were introduced or old ones resolved?

## When to prefer this

Use this endpoint when you specifically need to audit changes to an ONe service descriptor JSON document against its pinned SchemaStore definition. It is purpose-built for before/after diffing of that schema, reporting JSON pointer-level diffs and schema rule violations. Prefer it over generic JSON diff tools when you need ONe-schema-aware validation with error introduction/resolution tracking, not just structural diffing.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting exceeds 32 levels — parsing fails
- Invalid JSON submitted (e.g. YAML or TOML) — unsupported format error
- Malformed request body — missing before or after field
- Network or payment failure — no audit result returned

## How this service works

Change audit: ONe's service descriptor: Audit JSON changes and validate before/after for ONe's service descriptor. Uses a pinned SchemaStore definition on this PC. Reports JSON pointers and rule violations, added/removed/changed paths and introduced/resolved errors. Up to 100 KB per document; no YAML/TOML parsing or deployment/security guarantee. 0.01 USDC includes one two-document change audit.

## Output

Returns a structured diff report including JSON pointers for added, removed, and changed paths between the before and after documents, along with a list of rule violations per the pinned SchemaStore definition, flagging which errors were introduced and which were resolved by the change.
