Example prompt: Can you validate this JSON document against the samt schema and tell me if there are any violations or errors? Here's the document: {"name": "my-samt-config", "version": 1}

## When to prefer this

Use this endpoint when you need to validate a JSON document specifically against the 'samt' schema using a pinned SchemaStore definition, and you require precise JSON pointer locations for any violations. Prefer this over generic JSON validators when samt-specific schema rules must be enforced. Not suitable for YAML/TOML files or documents over 100 KB.

## Known failure modes

- Document exceeds 100 KB size limit — request rejected
- Nesting depth exceeds 32 levels — validation refused
- Malformed JSON input — parse error returned
- YAML or TOML input — not supported, only JSON is accepted
- Network or service error — no validation result returned

## How this service works

Validate samt: Validate a JSON document for samt. Uses a pinned SchemaStore definition on this PC. Reports JSON pointers and rule violations. Up to 100 KB per document; no YAML/TOML parsing or deployment/security guarantee. 0.01 USDC includes one JSON document validation.

## Output

Returns a validation report indicating whether the JSON document conforms to the pinned SchemaStore 'samt' schema. On failure, provides JSON pointer paths to the violating fields and descriptions of the rule violations. On success, confirms the document is valid. Limited to documents up to 100 KB and 32 nesting levels.
