Websites with no API

How to get work done on a website with no API

A lot of the work that matters sits behind a login on a site that was never built to be automated. Kaer opens it in its own browser, does the steps you ask for, and hands control back to you where it should: signing in, paying, confirming.

Before you start

What you need

01
A Kaer account (the Starter plan is free).

02
The site's address and what you want done there.

03
Your sign-in for the site, if it needs one. You type it yourself.

Step by step

How to do it

  1. Describe the job in a Work chat

    Start a chat and brief it the way you would a colleague, naming the site: “log in to the supplier portal and download this month's invoices”, or “check whether Friday at 14:00 is free and hold it”.

  2. Watch it work in the Errand pane

    A live browser opens beside the chat, labelled Errand, with the site's address and a Live badge. You see Kaer's cursor and every step as it happens; the footer reads “Kaer has control”.

  3. Take over when it is your turn

    When the site asks for a password, a one-time code or card details, Kaer stops and the footer says it is your turn. Click Take over, type the details yourself, then Hand back. Kaer can't see or keep your password.

  4. Approve the click that commits

    Before a click that pays, books or confirms, Kaer asks you: Approve, or Check it myself. Nothing is bought or confirmed until you say so.

  5. Keep the result

    Kaer reports what it did in the chat. The browser closes when the job is done, or after ten minutes with nothing to do; ask again and it opens a fresh one.

Where it stops for you

The parts that stay yours

01

Passwords, one-time codes and card details

You type them, Kaer never sees them.

02

Payments, bookings and confirmations

Held until you click Approve.

03

Security checks and sites that block automated browsers

Handed to you, never worked around.

Questions

Do I have to give Kaer my password?
No. When a site needs a sign-in, Kaer hands you the browser and you type it yourself; Kaer can't see or keep it. If you ask Kaer to create a new account on a site, it makes a strong password and saves it in your Secrets without ever seeing it.
What happens when a site shows a captcha?
Kaer doesn't solve or get around security checks. It hands you the browser, you complete the check, and you hand back.
Does it work on every website?
It works on sites that work in an ordinary browser. Some sites block automated browsers outright; when one does, Kaer tells you and offers you control rather than trying to get past it.
