The API is auto-generated from your database and is designed to get you building as fast as possible, without writing a single line of code. You can use them directly from the browser (two-tier architecture), or as a complement to your own API server (three-tier architecture). Supabase provides a RESTful API using [PostgREST](https://postgrest.org/), a thin API layer on top of Postgres. It exposes everything you need from a CRUD API at the URL `https://.supabase.co/rest/v1/`. The REST interface is automatically reflected from your database's schema and is: - **Instant and auto-generated:** As you update your database the changes are immediately accessible through your API. - **Self documenting:** Supabase generates documentation in the Dashboard which updates as you make database changes. - **Secure:** The API is configured to work with Postgres's Row Level Security, provisioned behind an API gateway with key-auth enabled. - **Fast:** Our benchmarks for basic reads are more than 300% faster than Firebase. The API is a very thin layer on top of Postgres, which does most of the heavy lifting. - **Scalable:** The API can serve thousands of simultaneous requests, and works well for Serverless workloads. The reflected API is designed to retain as much of Postgres' capability as possible including: - Basic CRUD operations (Create/Read/Update/Delete) - Arbitrarily deep relationships among tables/views, functions that return table types can also nest related tables/views. - Works with Postgres Views, Materialized Views and Foreign Tables - Works with Postgres Functions - User defined computed columns and computed relationships - The Postgres security model - including Row Level Security, Roles, and Grants. The REST API resolves all requests to a single SQL statement leading to fast response times and high throughput.
