Convert JSON to Prisma Schema API

Hosted on ApyHub

What it does

JSON to Prisma Schema converts JSON into a Prisma schema, either from a raw JSON payload, an uploaded JSON file, or a JSON resource at a public URL. You can get the result back as raw JSON, a downloadable .prisma file, or a pre-signed S3 URL to the generated file.

Use it when you need to turn example data or an existing JSON payload into a starting Prisma data model. The service accepts JSON as a request body, a binary JSON file, or a url pointing to a publicly accessible JSON resource. For generation options, it supports provider (postgresql, mysql, sqlite, or mongodb) and an optional rootModelName. Some endpoints also accept an output name for the generated file.

The raw response includes the generated schema text plus supporting meta, enums, models, warnings, and confidence fields. That makes it useful when you want to inspect or post-process the generated schema in your own pipeline. If you prefer file delivery, the file endpoints return the .prisma content directly, or a data URL pointing to the saved file.

A typical use case is bootstrapping a Prisma model from API fixtures, import samples, or a JSON export before you wire it into a database migration workflow.
