## 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-dss-2-0-0-json-schema-validator-f377051b -d '<json body>'
```

Example prompt: Audit the change I made to my dss-2.0.0.json config — here's the before document and the after document — and tell me which paths were added, removed, or changed, and whether any new schema violations were introduced or old ones resolved.

## When to prefer this

Choose this endpoint when you specifically need to validate JSON changes against the dss-2.0.0.json SchemaStore schema, want a diff of added/removed/changed paths alongside introduced or resolved errors, and your documents are under 100 KB. Not suitable for YAML/TOML files, other schema versions, or documents requiring deployment or security guarantees.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting depth exceeds 32 levels — parsing rejected
- Invalid JSON submitted (not parseable) — error returned
- YAML or TOML input submitted instead of JSON — not supported
- Network or payment failure for the 0.01 USDC x402 transaction
