}

Usage

• Import

import { Chat } from 'chatnio-node';
// or
const { Chat } = require("chatnio-node")

API

• Authentication API：Set your own API Key before chatting

import { setKey, setEndpoint } from 'chatnio-node';

// set your API Key
setKey("sk-...");

// set custom api endpoint (default: https://api.chatnio.net)
// setEndpoint("https://example.com/api");

• Chat API：Chat with multiple available models

import { Chat } from 'chatnio-node';

const chat = new Chat(-1); // id -1 (default): create new conversation

// using stream
chat.askStream({ 
    message: "hello world", 
    model: "gpt-3.5-turbo-0613", // default gpt-3
    web: false 
}, (res) => {
  console.log(res);
});

// don't use stream
chat.ask({ message: "hi" })
  .then(res => {
    console.log(res);
  })
  .catch(err => {
    console.log(err);
  });

• Conversation API：Manage chatting of different topics in conversation

import { getConversations, getConversation, deleteConversation } from 'chatnio-node';

// get all conversations of current user
const conversations = await getConversations();

// load conversation by id
const conversation = await getConversation(1);

// delete conversation by id
const state = await deleteConversation(1);

• Quota API：Elastic billing, usage-based

import { getQuota, buyQuota } from 'chatnio-node';

// get quota
const quota = await getQuota();

// buy quota
const state = await buyQuota(100);

• Subscription and Package：Subscribe for different plans

import { getPackage, getSubscription, buySubscription } from 'chatnio-node';

// get package
const pkg = await getPackage();

// get subscription
const subscription = await getSubscription();

// buy subscription
const state = await buySubscription(1, 1);

Example

Get Conversation Content

:bulb: For each new conversation, the first message received will be used as the conversation's name.

:warning:Although the getConversations() interface returns a data type of Conversation[], the message field of each Conversation is null . To obtain the complete history of a conversation, load the conversation by getConversation(id) interface.

import {Chat, getConversation, getConversations, setKey} from 'chatnio-node'

setKey("")

const msg1 = "Hello! My name is chat-nio."
const msg2 = "What's my name?"
// Create a new conversation. The first message received will be used as the conversation's name.
const chat = new Chat(-1)
let res = await chat.ask({
    message: msg1
})
console.log(res);
res = await chat.ask({
    message: msg2
})
console.log(res);

// Get the list of recent conversations, use the name to filter out conversation, and find the ID
const conversations = await getConversations();
const id = conversations.find(conv => conv.name === msg1).id

// Retrieve detailed conversation information by id
const conversation = await getConversation(id)
console.log(conversation);

// exit the program
process.exit(0)

Output may look like:

{
  message: 'Hello chat-nio! How can I assist you today?',
  keyword: '',
  quota: 0.00156
}
{ message: 'Your name is chat-nio.', keyword: '', quota: 0.002385 }
{
  auth: false,
  user_id: 4470,
  id: 45,
  name: 'Hello! My name is chat-nio.',
  message: [
    { srole: 'user', content: 'Hello! My name is chat-nio.' },
    { role: 'assistant', content: 'Hello chat-nio! How can I assist you today?' },
    { role: 'user', content: "What's my name?" },
    { role: 'assistant', content: 'Your name is chat-nio.' }
  ],
