The JSONBuddy API is a collection of reliable, developer-focused services for processing, validating, and transforming JSON, JSON Schema, and XML. It helps applications automate common data-quality and document-processing tasks, including schema-based JSON validation, JSON formatting and patching, JSON Schema documentation generation, XML well-formedness checks, deterministic XML formatting, and restricted XML signature verification. Designed for straightforward integration into development workflows, backend services, CI/CD pipelines, and data-processing systems, the API uses standard HTTP requests and returns structured, actionable results. Built-in request limits and rate limiting help provide predictable and secure operation.
