Example prompt: Can you validate this AssemblyScript JSON config for me and tell me which fields are invalid or violate the schema rules? Here's the document: {"targets":{"release":{"optimizeLevel":3,"shrinkLevel":1}}}

## When to prefer this

Choose this endpoint when you need to validate a JSON document specifically against the AssemblyScript SchemaStore schema and want precise JSON pointer-level violation reporting. It is ideal for CI pipelines, pre-commit hooks, or agent workflows that need fast, deterministic schema compliance checks without needing YAML/TOML parsing or deployment guarantees.

## Known failure modes

- Document exceeds 100 KB limit — rejected with size error
- JSON nesting deeper than 32 levels — rejected
- Malformed JSON submitted (not valid JSON at all) — parse error returned
- Network or service unavailability — HTTP 5xx response
- Payment not included or insufficient — HTTP 402 response

## How this service works

Validate AssemblyScript: Validate a JSON document for AssemblyScript. 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

The endpoint returns a validation report indicating whether the JSON document conforms to the pinned AssemblyScript SchemaStore definition, including a list of JSON pointer paths where rule violations occur, so the caller knows exactly which fields are invalid and why.
