# Standard API Layer Between AI, Enterprise  
Applications, and Multiple Data Sources

Standard API layer and database abstraction for all your data

## What is a standard API layer?

A standard API layer presents every data source — SQL, NoSQL, warehouses, and files — through one consistent HTTP interface. DreamFactory builds it automatically: schema introspection generates full CRUD REST endpoints with rich query parameters, standardized contracts across systems, and OpenAPI documentation for every API by default.

A shared logic layer adds transformations, validation, and business rules in one place, so applications, AI, and orchestration all consume the same governed contracts.

## How does DreamFactory provide a Standard API Layer?

DreamFactory builds a unified, standard API layer over every database, warehouse, file store, and legacy system, so AI agents and applications all use the same consistent, governed interface to your data. The DreamFactory AI data gateway acts as a database abstraction layer with built-in API generation and API documentation generation, giving you a single place to define, secure, and evolve data APIs.

### Automatically generated REST APIs

Zero-code API generation from existing schemas and services

### Consistent contracts

Standardized endpoints that provide true database abstraction across systems

### Shared logic layer

Central place to create transformations, validation, and business rules

### Documentation by default

Built-in OpenAPI generator and API document / 'doc' generator for every API

### Ready for AI and applications

One standard API layer serving both applications and LLM-driven workloads

## Automatically Generated REST APIs From Your Data

DreamFactory converts database schemas and other data sources into human-readable REST endpoints, so teams don't have to stand up new backend services for every source.

### Schema introspection

Read schemas and metadata to automatically build endpoints and query parameters

### Zero-code API generation

Create full CRUD APIs without writing backend code

### Database abstraction

Present SQL, NoSQL, warehouses, and files through a unified HTTP interface

### Fine-grained control

Configure methods, filters, and limits per service and endpoint

## Standardized API Contracts Across Systems

The standard API layer hides system-specific quirks behind a consistent set of patterns, so developers don't need to learn each backend's idiosyncrasies.

### Uniform URL structure

Predictable paths and naming conventions across all services

### Consistent HTTP verbs

Standard use of GET, POST, PUT, PATCH, DELETE for every resource

### Common error model

Shared error shapes and status codes instead of backend-specific messages

### Stable contracts

APIs that remain consistent even as underlying systems evolve

## Shared Logic and Transformation Layer

DreamFactory provides a single place to create shared logic at the standard API layer so business rules and transformations aren't duplicated across applications.

### Centralized transformations

Map, reshape, or enrich payloads at the gateway level

### Validation and normalization

Enforce schema rules before requests hit downstream systems

### Reusable endpoints

One implementation of common patterns reused across teams and projects

### Composable services

Combine calls to multiple backends into single composite APIs

## Built-In API Documentation Generation

Every service exposed through the standard API layer automatically gets documentation, so teams don't need separate tools to keep docs in sync.

### Auto-generated specs

OpenAPI generator output for every connected data and network source

### API documentation generation

Human-readable docs created directly from live service definitions

### API document / 'doc' generator

Machine-readable and human-readable artifacts for developers and partners

### Always up to date

Documentation refreshed automatically when APIs or schemas change

## Ready for AI, Applications, and Orchestration

The standard API layer is designed to serve both traditional applications and AI-driven workloads from the same stable surface.

### One layer for AI and applications

LLMs, agents, and services all consume the same governed APIs

### Database abstraction for AI

AI clients never talk SQL directly; they call standardized, secure endpoints

### Orchestration-friendly

Clean contracts for workflow engines and integration platforms

### Scalable foundation

Add new systems behind the standard API layer without changing client code

## Frequently asked questions

### How are the APIs generated?

DreamFactory reads schemas and metadata through introspection and automatically builds endpoints and query parameters — full CRUD APIs without writing backend code.

### Is documentation maintained by hand?

No. Every generated API includes built-in OpenAPI documentation that stays in step with the service definition.

### Can we add business logic to generated APIs?

Yes. A shared transformation and logic layer provides a central place for validation, transformations, and business rules applied across services.
