4EVER Security Token Service API

Welcome to the 4EVERLAND Security Token Service API


The 4EVERLAND Security Token Service is a service designed to generate temporary credentials, allowing you to request temporary credentials for partial or even full privileges for other users or a specified user.

4EVER Bucket STS fully compatible with AWS S3 STS. More information about STS can be found at AWS S3 STS.

How to use

This is obtained by taking the API Secret and the API Key from the Master key and sending them to the endpoint. By default, all 4EVERLAND STS requests are sent to https://endpoint.4everland.co.

Javascript example:

const {STSClient, AssumeRoleCommand} = require('@aws-sdk/client-sts')

const stsClient = new STSClient({
    endpoint: 'https://endpoint.4everland.co',
    region: 'us-west-1',
    credentials: {
        accessKeyId: 'Your api key.',
        secretAccessKey:  'Your api secret.',

const params = {
    RoleSessionName: "only-put-object",
    DurationSeconds: 3600,
    Policy: `{
