APIs & Integration

AIMatrix provides comprehensive API specifications and integration patterns for building robust, scalable applications. This documentation serves as the definitive API reference for the platform.

API Overview

The AIMatrix platform exposes multiple API interfaces designed for different use cases and integration patterns:

  • REST APIs - Traditional HTTP-based services for web and mobile applications
  • GraphQL APIs - Flexible query language for efficient data fetching
  • gRPC Services - High-performance RPC framework for microservices
  • WebSocket APIs - Real-time bidirectional communication
  • Event Streaming - Asynchronous message processing and notifications

Quick Start

Authentication

All AIMatrix APIs require authentication using API keys or OAuth 2.0 tokens:

X-RateLimit-Reset: 1640995200
X-RateLimit-Window: 3600

Rate Limiting Strategy

  • Tier-based limits based on subscription level
  • Per-endpoint limits for resource-intensive operations
  • Burst capacity for short-term spikes
  • Graceful degradation when limits are exceeded

Best Practices

API Design Principles

  1. RESTful Resource Design - Use nouns for resources, verbs for actions
  2. Consistent Naming - Use snake_case for JSON properties, kebab-case for URLs
  3. Proper HTTP Methods - GET for retrieval, POST for creation, PUT for updates
  4. Idempotency - Ensure safe retry behavior for critical operations
  5. Pagination - Always paginate list endpoints to prevent large responses

Performance Optimization

  1. Caching Strategy - Implement appropriate cache headers and ETags
  2. Request Batching - Group multiple operations into single requests
  3. Field Selection - Allow clients to specify required fields
  4. Compression - Enable gzip compression for large responses
  5. CDN Integration - Cache static resources and common responses

Security Best Practices

  1. Input Validation - Validate all input data thoroughly
  2. Output Encoding - Prevent injection attacks through proper encoding
  3. Rate Limiting - Implement appropriate rate limits per endpoint
  4. Audit Logging - Log all API access and modifications
  5. HTTPS Only - Force HTTPS for all API communications

Monitoring & Observability

  1. Request Tracing - Implement distributed tracing for complex operations
  2. Health Checks - Provide comprehensive health check endpoints
  3. Metrics Collection - Track key performance and business metrics
  4. Error Tracking - Implement detailed error logging and alerting
  5. API Analytics - Monitor usage patterns and performance trends

Development Tools

  1. Postman Collections - Pre-built API collections for testing
  2. OpenAPI Generator - Generate client SDKs from OpenAPI specs
  3. API Documentation - Interactive docs with try-it functionality
  4. Debug Mode - Detailed request/response logging for troubleshooting
  5. Sandbox Environment - Safe testing environment with sample data

  body: JSON.stringify({
    agent_id: '123',

// v2 (current)
const response = await fetch('/v2/agents/123/execute', {
  method: 'POST',
  body: JSON.stringify({
    query: 'Hello world',
    context: {}
  })
});

Breaking Changes

  • URL Structure - Agent execution moved to dedicated endpoint
  • Request Format - Standardized input/output format
  • Authentication - Enhanced security with scoped tokens
  • Error Handling - Improved error codes and messages
