## 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-drupal-info-json-schema-validator-33ff29ef -d '<json body>'
```

Example prompt: Can you audit the changes between my old and new Drupal info JSON files and tell me which paths were added, removed, or changed, and whether any new schema errors were introduced or old ones resolved?

## When to prefer this

Choose this endpoint when you specifically need to validate Drupal Info JSON documents against the SchemaStore-pinned Drupal Info schema and want a structured diff of schema violations introduced or resolved between two versions. Prefer it over generic JSON diff tools when Drupal-specific schema compliance is the goal.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting exceeds 32 levels — parsing refused
- Invalid JSON submitted in before or after field — parse error returned
- Schema definition unavailable on host — validation cannot proceed
- Malformed request body — missing required fields returns error

## How this service works

Change audit: Drupal Info: Audit JSON changes and validate before/after for Drupal Info. 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 report listing JSON pointer paths that were added, removed, or changed between the before and after documents, along with schema rule violations present in each, and a diff of introduced versus resolved errors — all based on a pinned SchemaStore Drupal Info definition.
