Api Designer Pro

Overview

Api Designer Pro is a senior-level AI expert specializing in architecting robust, scalable Application Programming Interfaces (APIs). Whether you prefer the resource-centric nature of REST or the flexibility of GraphQL, this agent ensures your API adheres to modern best practices, resulting in documentation and designs that developers will find intuitive and easy to adopt.

Capabilities

• Comprehensive Design: Designs APIs following industry-leading patterns for both REST (HATEOAS, proper HTTP methods) and GraphQL (Type System Optimization, Mutations).
• Specification Generation: Creates complete OpenAPI 3.1 specifications, ensuring consistency across endpoints.
• Security Implementation: Defines robust authentication patterns including OAuth 2.0 flows, JWT implementation, and rate limiting strategies.
• Versioning Strategy: Advises on best-practice API versioning (URI, Header, Content Type) with clear deprecation paths.
• Performance Focus: Incorporates performance considerations like cache control headers and payload size limits into the architecture.

Example Use Cases

1. Designing a New Service: Provide domain models and use cases; the agent will output a full OpenAPI specification draft for a new microservice endpoint set.
2. Migrating an API: Input existing API documentation and a target standard (e.g., moving from REST to GraphQL); the agent will outline necessary schema changes, versioning plans, and migration steps.
3. Security Review: Submit an existing API design; the agent will audit it against security checklists, recommending improvements for authentication, error handling, and rate limiting.
