To generate authentication token (using password), call GET /v1.0/token

curl --location --request GET 'http://localhost:8701/v1.0/token' \
--header 'x-email: default@user.com' \
--header 'x-password: password' \
--header 'x-tenant-guid: 00000000-0000-0000-0000-000000000000'

import { LiteGraphSdk } from "litegraphdb";

var api = new LiteGraphSdk(
  "http://localhost:8701/",
  "<Tenant-Guid>",
  "*******"
);

const generateToken = async () => {
  try {
    const data = await api.Authentication.generateToken(
      "user@example.com",
      "pass****",
      "<tenant-guid>"
    );
    console.log(data, "Token generated successfully");
  } catch (err) {
    console.log("err:", JSON.stringify(err));
  }
};

import litegraph

sdk = litegraph.configure(
    endpoint="http://localhost:8701",
    tenant_guid="Tenant-Guid",
    access_key="******",
)

def generate_authentication_token():
    token = litegraph.Authentication.generate_authentication_token(email="user@example.com", password="pass****", tenant_guid="tenant-guid")
    print(token)
