Convert JSON to Prisma Schema API

What it does

JSON to Prisma Schema converts JSON objects, JSON arrays, or a JSON file into a Prisma schema. Send raw JSON, a JSON URL, or an uploaded .json file, and get back generated Prisma schema text or a downloadable .prisma file.

Use provider to target postgresql, mysql, sqlite, or mongodb. You can also set rootModelName to control the top-level Prisma model name. For raw JSON requests, the service accepts either a plain JSON object as the body or a wrapped payload with json and optional config fields. That wrapped form lets you override generation settings inline.

The raw-output endpoints return a JSON response with the generated schema string, plus meta, models, enums, warnings, and confidence. The file-output endpoints return the schema as a binary .prisma download, or a pre-signed S3 URL in a data field when you want to store or fetch the file separately.

Use JSON to Prisma Schema when you need to bootstrap a data model from an existing API payload, sample export, or customer dataset. It is useful for turning real-world JSON structures into a starting Prisma schema before you refine relations, naming, and types.
