Grok Custom Connector for AI Video: Add Ziztu

• A Ziztu account. 40 free credits for scripts, character art, storyboards, voices and sound, plus your first 5 second video free, no card. More video starts at $12.
• Grok. xAI's docs say connectors are available to all Grok users. For Grok Business and Enterprise, a team admin must first provision the connector in the cloud console, so members ask their admin.
• A public address. Grok needs a server reachable over the public internet. https://getziztu.com/mcp is, so you need no tunnel.
• One honest note. xAI's page says only "complete any required authentication" for custom connectors. Ziztu's sign-in is standard OAuth 2.1 with dynamic client registration, and we have not yet watched it complete inside Grok. If it fails for you, tell us. In a local test, xAI's Grok Build CLI did detect Ziztu's sign-in (the 401 reply and the OAuth metadata). That is a terminal agent, not grok.com.

Once the first plan is back, these prompts take you from the plan to a film. Each one that costs credits tells the app to use a cap, and the app shows you the price first.

Make the first frames for that project with max_credits set to the quote. When they are done, show me the frames and wait. I will tell you whether to animate.

Animate shot 1 only, with max_credits set to its quote. Tell me what it cost and show me the clip before you do any other shot.

When I am happy with the clips, quote the music, make it with max_credits set to the quote, then export the film and tell me how to download it.

Use Ziztu to plan a 45 second anime episode in a hand-painted look about a girl who finds a sleeping whale made of cloud over her village. Give the girl and the whale a fixed look, plan the shots, and quote the first frames. Do not spend anything yet.

xAI's page says a team admin must first provision a connector in the cloud console before it is available to members. If you are the admin, provision Ziztu with the address above. If you are a member, send your admin this page and the address. Each member still signs in with their own Ziztu account, so credits and limits stay personal.

Ziztu is a studio for micro dramas and anime series, so the connection gives your AI app 30 tools for the whole job, not a single clip button:

• Plan. Ask the Director for the cast, the places and every shot of an episode, then apply the plan to a project.
• Price. Quote frames, clips or music before anything runs. The quote also lists any shot that is blocked and why.
• Make. Make the first frame of each shot, animate the shots you pick and generate the music, each with a spend cap you set.
• Keep going. Check jobs, check your credit balance and export the finished film as an MP4. The same project opens in the Ziztu studio, where you can edit it.
• Run apps. Start the one-shot Ziztu apps (animation, manga, story video and more) from the same chat.

The cast stays the same across every shot and every episode, because the characters live in the project and not in the chat.

This is The Wrong Wedding, a 32 second vertical episode made in Ziztu with the same three characters in all seven shots. It started from one sentence, the same kind of prompt you give your AI app.

The Wrong Wedding, episode 1: 32 seconds, seven shots, three characters, made in Ziztu from one sentence.

The prompt that made it

A live-action vertical micro drama, episode 1: on her wedding day a bride reads a message on the groom's phone and walks down the aisle anyway, smiling. End on a cliffhanger when she takes the microphone.

Giving an AI app a way to spend money needs hard limits. These are enforced by the Ziztu API, not by the chat, so the app cannot talk its way around them:

• A spend cap on every paid call. max_credits is required on first frames, clips, music and app runs. If the exact price is higher, the call is refused before anything starts.
• A second yes above 500 credits. A bigger spend also needs confirm: true, and the tool descriptions tell the app to ask you first.
• Price before spend. The quote tool and dry_run: true return the exact credits and start nothing.
• You choose the permissions. The consent screen lists three: see your account, create and generate, and export films. Untick Create and generate and the app can look but cannot spend.
• Disconnect any time. Open getziztu.com/oauth/connections, find the app and end it. The next call fails at once.

A connection itself costs nothing. You pay in credits, on your own Ziztu account, and the price of each step is shown before it runs.

• Free to start: 40 free credits for scripts, character art, storyboards, voices and sound, plus your first 5 second video free, no card. More video starts at $12.
• Video needs a plan. Plans start at $12 a month. On Starter, a 5 second clip costs about $0.37 at 480p or $0.60 at 768p. See pricing for every plan and pack.
• Your app is billed separately. Claude, ChatGPT, Codex, Grok and Cursor have their own plans and limits. Ziztu only charges for what runs in Ziztu.

• Grok cannot finish the sign-in. Check that you can open https://getziztu.com in a normal browser tab and that pop-ups are allowed, then try again. If Grok still cannot sign in, tell us which step failed so we can fix it.
• Ziztu does not show up for a team member. On Business and Enterprise an admin must provision the connector first.
• The sign-in window does not open or closes at once. Allow pop-ups for the app, then start the connection again. In a terminal app, copy the link it prints into your browser.
• The app can plan but says it cannot spend. The connection was made without Create and generate. Disconnect it at getziztu.com/oauth/connections, connect again and keep that box ticked.
• A call is refused with over_max_credits. The cap was lower than the exact price. Ask the app for the quote, then set max_credits at or just above it.
• A call is refused with confirm_required. The price is above 500 credits. Read the price, and if you agree, tell the app to continue with confirm set to true.
• It says you have no credits (HTTP 402). Ask the app to check your balance. Free credits cover the planning and a new account's first 5 second clip; more video starts on a plan.
• The app asks you to sign in again. Do it. Access renews by itself, but ending a connection on the connected apps page removes it for good.

The steps for each app follow its own official page, read on 18 October 2026. Apps change their menus, so if a label looks different, trust the app and the page below.
