MemEvolve API Reference

This reference covers all MemEvolve API endpoints, configuration options, and usage patterns for integrating memory capabilities into your applications.

🌐 API Architecture

MemEvolve provides two primary interfaces:

  1. Proxy API: Transparent OpenAI-compatible API that adds memory automatically
  2. Management API: Direct endpoints for memory inspection and control

🚀 Proxy API (OpenAI-Compatible)

The proxy API is a drop-in replacement for any OpenAI-compatible LLM service. All standard OpenAI endpoints are supported with automatic memory integration.

Base URL

http://localhost:11436/v1

Supported Endpoints

Chat Completions

POST /v1/chat/completions

Request Body: Standard OpenAI chat completion format

{
  "model": "your-model",
  "messages": [
    {"role": "user", "content": "How do I implement caching?"}
  ],
  "max_tokens": 1000
}

MemEvolve Enhancement: Automatically injects relevant memories into the conversation context.

Embeddings

POST /v1/embeddings

Request Body: Standard OpenAI embedding format

{
  "model": "your-embedding-model",
  "input": "Text to embed"
}

Note: Routes to MEMEVOLVE_EMBEDDING_BASE_URL if configured, otherwise uses MEMEVOLVE_UPSTREAM_BASE_URL.

🔧 Management API

⚠️ Important: Management endpoints provide basic functionality. Advanced features are in development.

Direct endpoints for memory system management and inspection.

  • Proxy Requests: Pass-through authentication to upstream API
  • Memory API: Uses MEMEVOLVE_MEMORY_API_KEY (falls back to upstream if not set)

📊 Response Codes

  • 200: Success
  • 400: Bad Request (invalid parameters)
  • 404: Not Found (endpoint doesn't exist)
  • 422: Unprocessable Entity (validation failed)
  • 500: Internal Server Error
  • 503: Service Unavailable (upstream API down or system not initialized)

🚨 Current Issues & Limitations

🟡 v2.1.0 Minor Issues

Non-Critical Issues Being Refined:

  • Memory Encoding Quality: Some memories contain verbose content that could be more concise

    • Impact: Minor effect on memory quality and retrieval relevance
    • Status: Content improvements in progress, system functional

  • Token Efficiency Calculations: Analytics being refined for accurate business metrics

    • Impact: Business analytics may show rough estimates
    • Status: Calculations being enhanced, core functionality unaffected

  • Business Scoring Enhancement: ROI tracking structure implemented, real-time metrics in development

    • Impact: Advanced analytics incomplete, basic scoring functional
    • Status: Framework operational, enhancements in progress

✅ Resolved Issues

  • Configuration Sync: Evolution system now respects environment boundaries (TOP_K_MAX=10)
  • Hardcoded Values: All systematic hardcoded violations eliminated
  • Import Errors: Missing imports resolved, API server starts successfully

Known Limitations

  • Dashboard Data API: Business analytics integration currently failing - may return error for comprehensive metrics
  • Memory Search: May return empty content results with valid scores
  • Evolution System: Auto-evolution requires sufficient activity to trigger
  • Quality Scoring: Some responses show N/A scores in older versions (resolved in current code)

Development vs Production

Main API Ready for Use: The OpenAI-compatible chat completions endpoint is fully functional and ready for production use.

Management API in Testing: Management endpoints and evolution/scoring features are in active development and may not function as expected. Use this branch for:

  • Development and testing of new features
  • Understanding system architecture and capabilities
  • Contributing to issue resolution
  • Testing management endpoints and advanced features

For detailed issue status and implementation plans, see troubleshooting guide and dev_tasks.md.

🚀 Usage Examples

🔧 Troubleshooting

  • Connection Refused: Check if MemEvolve server is running on correct host/port
  • Empty Results: Verify memory has been populated and search query is relevant
  • Dashboard Data Error: Business analytics integration issue - check comprehensive metrics availability
  • Memory Search Issues: May return empty content with valid scores - check memory population
  • Quality Scoring Issues: Enable debug logging with MEMEVOLVE_LOG_MIDDLEWARE_ENABLE=true
  • Slow Responses: Check upstream API performance and network connectivity
  • Authentication Errors: Verify API keys are correctly configured
  • Evolution Not Starting: Requires sufficient API activity - check auto-evolution trigger conditions

For detailed troubleshooting, see the troubleshooting guide and quality scoring documentation.
