Platform Overview

API Now! divides backend development into two distinct layers: the Control Plane (where you visually model your business rules) and the Serverless Runtime (where your databases are generated and run).

This separation ensures that you can adjust your database structure and API paths at any time without worrying about server provisioning, database migrations, or manual code deploys.

The Control Plane

The Control Plane is your design studio, accessible directly at app.apinow.app (or via the main website at apinow.app). It stores the metadata blueprints (what your entities are, how they relate, and who can access them) but does not store your actual customer data.

It consists of three core visual tools:

Domain Modeler

The Domain Modeler is a form-based visual workspace where you map out your database structure.

• Entities: Define the business records you want to track (e.g., Customer, Order, Product).
• Properties & Constraints: Set up the details of those records (e.g., product names, required fields, unique values).
• Associations: Establish relationships between tables (e.g., a Customer has many Orders).
• Semantic Module Tags: Apply semantics (like Email, Password, SoftDelete) to automate backend operations.

API Modeler

The API Modeler configures how external applications connect to your database.

• Action Exposure: Explicitly select which actions to permit on each entity (e.g., enable “Create” and “Read” but disable “Delete”).
• Routing & Paths: Customize endpoint names and map nested sub-resources (e.g., placing comments under posts).
• Security & Gateways: Configure API key authentication, rate limits, and access controls.

Data Catalog

The Data Catalog is a library of pre-configured data blueprints. Instead of designing standard database structures from scratch, you can browse, import, or publish pre-made models (like user profiles or product inventories) to accelerate your project setup.

The Serverless Runtime

The Serverless Runtime is the engine room. Built on our patent-pending dynamic metadata-driven database and API runtime interpretive environment, the runtime reads your metadata blueprint and brings your backend to life instantly.

Automatic Database Provisioning

The runtime automatically connects to a dedicated PostgreSQL database, creates the required tables, calculates schema diffs, runs schema updates, and establishes the correct indexes and constraints using our patent-pending Topological Schema Analysis & Mutation Engine (Delta Calculator). You never have to write SQL or run manual database migrations.

The Semantic Engine

Instead of executing custom code, the runtime runs a Semantic Engine powered by our patent-pending Dynamic Semantic Pipeline. When an API request comes in:

1. It validates that the input matches your constraints and Semantic module rules (e.g., rejecting an invalid email address).
2. It applies automated security transformations (e.g., encrypting passwords on write, or redacting sensitive data on read).
3. It runs the database query and returns a standardized JSON response.

Key Platform Benefits

By decoupling design from execution, API Now! delivers a highly secure and flexible environment:

• Zero-Maintenance Database: Tables, relationships, and performance indexes are automatically managed.
• Instant Updates: Modifying a field structure or adding an API action takes seconds. The runtime immediately updates the database schema and API routes without downtime.
• Consistent Security: Semantic modules guarantee that sensitive properties (like passwords or credit card numbers) are encrypted and secured automatically at the database level.
