Using the Chab app

The signed-in app at www.chab.ai shows your credits, lets you try tools in the browser and lists everything your agents ran. Your agents do most of the work over hosted MCP, the CLI or the REST API; the app is where you check on them, create keys and pay.

Overview

The Overview shows three things:

• Credits: one balance with everything you can spend. Plan credits, credit packs and the welcome credits you got at signup all count the same way.
• Connect your agent: the setup prompt. Paste it into Claude Code, Codex, Cursor, ChatGPT, Claude.ai or any MCP client and the agent connects itself. The public page /connect lists the steps for every client.
• Recent operations: the last runs with their status and credits. Open one to see its result.

A card appears at the top only when something needs your attention, for example when credits run out or a payment failed.

Playground

The Playground runs any tool from the browser. Pick a tool, fill in the main field (a search query, a URL or some text) and press Run. The result shows below the form: data as formatted JSON, screenshots as images and files as downloads.

You do not need to paste an API key. The Playground creates a key named Playground (browser) on your first run, replaces it the next time you open the page and lets it expire after a day, so at most one exists. Team owners and admins get it; other members paste their own key. Optional parameters, the raw JSON editor and a different API key are under Advanced options. Show as code gives the same request as a curl command with $CHAB_API_TOKEN in place of the key.

Every run costs the same credits as the same call over the API.

Operations

Operations lists every tool run of your team, newest first. Search by tool name or operation ID, filter by status or tool family, and open Filters for more: only runs with a file, a specific API key or a date range. Open a row to see the result, download files, cancel a running operation or run it again in the Playground.

Team owners and admins see all runs of the team. Other members see the Overview and the Playground.

API keys

API keys let scripts, the CLI and agents call Chab over REST. Hosted MCP clients do not need one; they connect with one approval click in the browser. Each key has its own tools, an optional spending limit, optional allowed networks and an optional expiry date. The plain key is shown once, right after you create it.

Credits & billing

Credits & billing shows your balance, your plan and the history of every charge and top-up. See plans opens the billing portal, where you start, change or cancel a plan. Credit packs top up any paid plan. Usage limits for each tool family are in the folded Usage limits section.

Settings

Settings holds your profile, team members, MCP connections (the clients that signed in through hosted MCP, which you can revoke), projects and the team audit log.

What is kept and for how long

Chab never shows provider credentials, raw provider payloads or storage paths.
