## 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 validate-pgrls-json-schema-validator-e2dcf934 -d '<json body>'
```

Example prompt: Can you validate this JSON document against the pgrls schema and tell me which fields or rules are violated? Here's the document: {"name": "my-pgrls-config", "version": "1.0"}.

## When to prefer this

Choose this endpoint when you need to validate a JSON document specifically against the pgrls schema definition (pinned from SchemaStore). It is purpose-built for pgrls config validation with precise JSON pointer error reporting, making it ideal for CI/CD pipelines, developer tooling, or any workflow that needs to confirm pgrls JSON correctness before use. Not suitable for YAML or TOML formats, and does not provide deployment or security guarantees.

## Known failure modes

- Document exceeds 100 KB size limit — request rejected
- Nesting depth exceeds 32 levels — validation not performed
- Input is not valid JSON — parsing error returned
- pgrls schema definition unavailable or pinned version mismatch — validation may fail
- Malformed request body — HTTP 400 returned
