Prevent API Response Failures with Automated JSON Validation

JSON Schema provides automatic validation of API responses to catch data structure mismatches before they cause application failures. As a vocabulary standard developed since 2009 and now an IETF draft standard, JSON Schema is essential knowledge for developers working with APIs, configurations, or structured data. By validating data at the API boundary before it reaches your business logic, you eliminate silent failures caused by unexpected null values or missing fields.
