Questions
 
Schema or example — which should I paste? 
Either. A JSON Schema (with type/properties, formats, enums, min/max and $ref) is followed exactly. A sample JSON object is used as a template and field names like email, price or createdAt get realistic values.
Can I get the same data again? 
Yes. The seed makes output repeatable; change it for a new set.
Is my schema uploaded? 
No. Data is generated in your browser with Faker.
