## 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-opctl-schema-validator-44410480 -d '<json body>'
```

Example prompt: Can you audit my Opctl JSON change — here's the before document and the after document — and tell me what paths were added, removed, or changed, and whether any new schema validation errors were introduced or old ones resolved?

## When to prefer this

Choose this endpoint when you specifically need to audit JSON configuration changes for Opctl against the official pinned SchemaStore definition, particularly when you want to understand which fields changed and whether those changes introduced or resolved validation errors. It is purpose-built for Opctl JSON diffing and schema compliance checking, not general JSON comparison or deployment validation.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- Nesting depth exceeds 32 levels — parsing halted
- Invalid JSON submitted for before or after — parse error returned
- YAML or TOML input provided instead of JSON — not supported
- Network or payment processing failure — no result returned
