JSON Schema Validator - Validate Data Against Any Schema

Validate JSON data against JSON Schema definitions. Catches type errors, missing required fields, pattern mismatches, and constraint violations. Supports inline data or URL fetch.

Key Features

Draft-07 compatible JSON Schema validation
Inline JSON or fetch from URL for both data and schema
Strict mode rejects extra properties not in schema
Detailed error reports with path, expected vs received values

Cost

Typical runs cost less than $0.01. Pure computation, no web scraping.

Input Example

{
    "jsonData": {"name": "John", "age": "not a number"},
    "schema": {"type": "object", "properties": {"name": {"type": "string"}, "age": {"type": "integer"}}, "required": ["name", "age"]}
}

Output Example

{
    "valid": false,
    "errorCount": 1,
    "errors": [{"path": ".age", "message": "Expected type integer, got string"}]
}

Use Cases

API development: validate request/response payloads before deployment
Data pipelines: ensure data quality at ingestion
