What you get

A drop-in z.object({…}) schema and an inferred TypeScript type from a JSON sample. Pass an array of objects to widen the schema across multiple shapes.

Format detection

Strings that look like UUIDs, emails, dates, ISO timestamps, or URLs get the matching Zod refinement so validation is meaningful out of the box.
