How this service works

Use this service before importing or publishing JSON to check it against a restricted draft-07 schema. Send dataJson and schemaJson as JSON-encoded strings. Max 256 KiB UTF-8 each, depth 32; bounded node and work limits. Supports types, required properties, items, enums and numeric/length bounds. No regex, combinators or external references. Invalid business data returns valid=false.

Output

Returns a validation result object containing a boolean 'valid' field indicating whether the data conforms to the schema, plus a list of validation errors or constraint violations (e.g. missing required properties, wrong types, out-of-range values, invalid enum values) if validation fails.

Example use cases

Pre-import data quality gate

“I'm about to import a batch of product records into our database — can you validate this product JSON against our schema that requires 'sku' (string), 'price' (number, min 0), and 'category' (enum: 'electronics', 'apparel', 'home') before I proceed?”

API payload validation before publishing

“Before I publish this event payload to our API, check it against our event schema — the data needs a required 'eventType' string and a 'timestamp' integer, and I want to know immediately if anything is missing or the wrong type.”

Config file schema enforcement

“Can you validate this app configuration JSON against my config schema? The schema requires 'maxRetries' as an integer between 1 and 10, 'logLevel' as one of 'debug', 'info', 'warn', or 'error', and 'timeout' as a positive number — tell me if the config is valid or list any violations.”

When to prefer

Choose this endpoint when you need a lightweight, schema-constrained JSON validator that enforces draft-07 semantics (types, required, items, enums, numeric/length bounds) without needing regex, combinators, or external $ref resolution. Ideal for pre-import or pre-publish validation pipelines where you want a fast, bounded, pay-per-call check with predictable cost ($0.002 per call) and no server infrastructure to manage. Prefer alternatives if you need full draft-07 feature coverage including regex patterns, anyOf/oneOf/allOf combinators, or $ref to external schemas.

Side effects

Input JSON strings exceed 256 KiB limit — request rejected
Schema depth exceeds 32 levels — validation refused
Schema node count exceeds 2000 — work cap exceeded
Data node count exceeds 10000 — node limit hit
Schema contains regex patterns — not supported, returns error
Schema uses combinators (anyOf, oneOf, allOf) — not supported
Schema references external URIs — not supported
Malformed JSON in dataJson or schemaJson — parse error returned
Work cap of 50000 operations exceeded for complex schemas — error returned
