Example Usage

​
cURL

curl -X GET "http://localhost:8000/api/v1/chats/user/user123?limit=10&offset=0&order=desc" \
  -H "X-API-Key: your-tenant-api-key"

​
JavaScript

const userId = 'user123';
const params = new URLSearchParams({
  limit: '10',
  offset: '0',
  order: 'desc'
});

fetch(`http://localhost:8000/api/v1/chats/user/${userId}?${params}`, {
  method: 'GET',
  headers: {
    'X-API-Key': 'your-tenant-api-key'
  }
})
.then(response => response.json())
.then(data => {
  console.log(`Found ${data.total} chats for user`);
  data.chats.forEach(chat => {
    console.log(`Chat: ${chat.title} (${chat.message_count} messages)`);
  });
})
.catch(error => console.error('Error:', error));

​
Python

import requests

user_id = "user123"
url = f"http://localhost:8000/api/v1/chats/user/{user_id}"
headers = {"X-API-Key": "your-tenant-api-key"}
params = {
    "limit": 10,
    "offset": 0,
    "order": "desc"
}

response = requests.get(url, headers=headers, params=params)
data = response.json()

print(f"Found {data['total']} chats for user {user_id}")
for chat in data['chats']:
    print(f"Chat: {chat['title']} ({chat['message_count']} messages)")

​
Notes

  • Results are automatically filtered to only include chats belonging to your tenant
  • The order parameter sorts chats by their created_at timestamp
  • last_message_at will be null for chats with no messages
  • message_count provides a quick way to see chat activity without fetching all messages
  • Use pagination for users with many chats to improve performance
