## 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 change-audit-cargo-manifest-schema-validator-db0be0f1 -d '<json body>'
```

Example prompt: Can you audit the change I made to my Cargo manifest — here's the before JSON and the after JSON — and tell me which fields 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 need schema-aware change auditing specifically for Cargo (Rust package) manifest files in JSON format, and you want both a structural diff (added/removed/changed paths) and schema validation results (introduced/resolved errors) in a single call. Prefer this over generic JSON diff tools when Cargo-specific SchemaStore rules matter, or over generic JSON schema validators when you need to compare two document states simultaneously.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting exceeds 32 levels — request rejected
- Invalid JSON submitted (YAML/TOML not supported) — parse error returned
- Malformed request body — HTTP 400 response
- Payment not included or insufficient — HTTP 402 response

## How this service works

Change audit: Cargo Manifest: Audit JSON changes and validate before/after for Cargo Manifest. 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 of the two Cargo manifest JSON documents including: JSON pointers for all added, removed, and changed paths; schema rule violations present in before and/or after; newly introduced errors from the change; and errors resolved by the change — all validated against a pinned SchemaStore Cargo manifest definition.
