What APIGenerator reads from your schema

Tables, columns and types for PostgreSQL, MySQL and SQLite.
Primary keys, foreign keys and unique constraints.
Nullable and default values, which become validation rules.
Prisma models and relations.

CREATE TABLE orders (
  id          uuid PRIMARY KEY,
  customer_id uuid REFERENCES customers,
  status      text NOT NULL,
  total       numeric(10,2),
  placed_at   timestamptz
);

GET/v1/orders

GET/v1/customers/{id}/orders

From tables to a documented API

A resource per table with list, read, create, update and delete.
Relations from foreign keys, with nested routes and expandable fields.
Hidden columns you choose, such as password hashes or internal flags.
REST, graphql api and MCP output from the same schema.
Docs, contract tests and a mock server.

Your data stays where it is

Only the schema is used to generate the API. When you export the code and run it next to your database, the data never leaves your infrastructure. For agents, see the postgres mcp server.

Questions about database to api

No. APIGenerator needs only the schema. Your rows stay in your database.

Yes. Exclude any table or column before you deploy, and it never appears in the API, docs or MCP tools.

Upload the new schema and APIGenerator updates the endpoints, docs, tests and tools. Breaking changes can ship as a new API version.
