API Reference

Complete reference for the MemSync REST API

MemSync API Reference

The MemSync REST API provides programmatic access to memory management, user profiles, and integrations. This comprehensive reference covers all endpoints, request/response formats, and implementation examples.

Base URL

All API requests should be made to:

https://api.memchat.io/v1

Authentication

MemSync uses API key-based authentication. Include your API key in the X-API-Key header for all requests:

X-API-Key: YOUR_API_KEY

API keys are required for all requests. Keep your API key secure and do not share it publicly.

Quick Start

Here’s how to make your first API call:

Python

import requests

headers = {
    "X-API-Key": "YOUR_API_KEY",
    "Content-Type": "application/json"
}

# Store a conversation
response = requests.post("https://api.memchat.io/v1/memories",
    headers=headers,
    json={
        "messages": [
            {"role": "user", "content": "I'm a software engineer who loves hiking"},
            {"role": "assistant", "content": "That's a great combination of technical and outdoor interests!"}
        ],
        "agent_id": "my-chatbot",
        "thread_id": "conversation-123",
        "source": "chat"
    }
)

print(response.json())

Standard Response Format

All API responses follow a consistent format:

Success Response

{
  "data": {
    // Response data specific to the endpoint
  },
  "status": "success",
  "timestamp": "2024-03-20T10:00:00Z"
}

Error Response

{
  "error": {
    "code": "VALIDATION_ERROR",
    "message": "Invalid request format",
    "details": {
      "field": "messages",
      "reason": "At least one message is required"
    }
  },
  "status": "error",
  "timestamp": "2024-03-20T10:00:00Z"
}

HTTP Status Codes

Status Code	Description
200	Success - Request completed successfully
201	Created - Resource created successfully
400	Bad Request - Invalid request format or parameters
401	Unauthorized - Invalid or missing authentication
403	Forbidden - Insufficient permissions
404	Not Found - Resource does not exist
422	Unprocessable Entity - Valid request but cannot be processed
429	Too Many Requests - Rate limit exceeded
500	Internal Server Error - Server error occurred

Rate Limiting

The MemSync API implements rate limiting to ensure service quality:

• Standard Rate Limit: 100 requests per minute per user
• Integration Endpoints: 10 requests per minute per user
• Search Endpoints: 50 requests per minute per user

Rate Limit Headers

X-RateLimit-Limit: 100
X-RateLimit-Remaining: 95
X-RateLimit-Reset: 1640995200

Handling Rate Limits

import time
import requests

def make_request_with_retry(url, headers, data, max_retries=3):
    for attempt in range(max_retries):
        response = requests.post(url, headers=headers, json=data)
        
        if response.status_code == 429:
            # Rate limited, wait and retry
            retry_after = int(response.headers.get('Retry-After', 60))
            time.sleep(retry_after)
            continue
        
        return response
    
    raise Exception("Max retries exceeded")

Pagination

Many endpoints support pagination for large datasets:

Request Parameters

{
  "page": 1,
  "page_size": 20
}

Response Format

{
  "data": [...],
  "pagination": {
    "page": 1,
    "page_size": 20,
    "total_items": 150,
    "total_pages": 8,
    "has_next": true,
    "has_previous": false
  }
}

Example Implementation

def get_all_memories(headers):
    all_memories = []
    page = 1
    
    while True:
        response = requests.get(f"https://api.memchat.io/v1/memories",
            headers=headers,
            params={"page": page, "page_size": 50}
        )
        
        data = response.json()
        all_memories.extend(data['data'])
        
        if not data['pagination']['has_next']:
            break
            
        page += 1
    
    return all_memories
