API Design

Design RESTful and GraphQL APIs with best practices, versioning, and documentation.

What is API Design?

API Design is one of 70 specialized agent skills built into the Multos AI platform. When you describe a task related to api, this skill activates automatically — bringing domain-specific knowledge about api design, rest api, api best practices directly into your development workflow.

Helps architect APIs that are intuitive, consistent, and evolvable. Generates proper resource naming, HTTP methods, status codes, pagination, versioning, and error formats. Understands trade-offs between REST, GraphQL, and RPC. Generates OpenAPI specs.

Key Capabilities

  • ✓Generates complete, working implementations for api design with proper error handling and edge cases
  • ✓Understands best practices and security patterns specific to api development
  • ✓Provides step-by-step guidance from setup through production deployment
  • ✓Adapts to your existing codebase — works with any framework, language, or architecture
  • ✓Generates tests alongside implementation code to ensure reliability
  • ✓Specialized knowledge of rest api patterns, common pitfalls, and optimization techniques

How to Use API Design on Multos AI

Example Prompts

  • "Design a REST API for a multi-tenant SaaS with proper hierarchy"
  • "Create an OpenAPI spec for my payment processing API"
  • "Review my API design for consistency and improvements"

Example Output

// Consistent error response format
{
  "error": {
    "code": "VALIDATION_ERROR",
    "message": "Request validation failed",
    "details": [
      { "field": "email", "message": "Must be a valid email" },
      { "field": "plan", "message": "Must be one of: free, pro, enterprise" }
    ],
    "requestId": "req_abc123"
  }
}

Real-World Use Case

A company with 5 microservices and inconsistent patterns created a unified API style guide. The skill identified inconsistencies and generated a standardized design document with migration paths plus an OpenAPI spec for SDK generation.
