Authentication API for browser agents

Send credentials to our API, get back live authenticated browser sessions.

Agent run · Login

How It Works

Send credentials, get authenticated sessions. It's that simple.

Send Credentials

POST your username/password to our login API endpoint along with the target domain.

We Handle Login

Our service automates the login process using our own browser agents and proxies.

Get Live Sessions

Receive authenticated cookies and session data that you can inject into your browser agent.

Core Features

Core endpoints for complete authentication lifecycle management.

Login

Send credentials and login method, get back live authenticated browser sessions with cookies

Signup

Auto-create accounts with email verification, returns session + credential reference for future use

Refresh

Use stored credential references to generate fresh authenticated sessions when current ones expire

Built for Developers

One simple POST endpoint that takes credentials and returns live authenticated sessions. No complex integration required.

// Send credentials to get authenticated session

const loginResponse = await fetch("https://prismai.sh/api/login", {

method: "POST",

headers: {

Authorization: "Bearer pk_your_api_key",

"Content-Type": "application/json"

body: JSON.stringify({

domain: "https://github.com/login",

loginMethod: "password",

cred: {

username: "agent@company.com",

password: "secure_password"

}

})

});

The Agent Authentication Problem

Browser agents struggle with login automation. We solve this by handling the authentication and returning ready-to-use sessions.

Brittle Hacks

Writing login automation scripts for every website is brittle

Unsafe Credentials

Session management across agents are complex and insecure

No Session Persistence

Agents lose authentication state between runs

Without Prism Auth

With Prism Auth

Secure • Automated • Persistent

Stop struggling with browser agent authentication.

Start using Prism. Focus on building your agent's core functionality, not logging into websites.
