How to Buy SuperGrok and SuperGrok Heavy with USDT (2026): price, top-up on your own Grok account, the free-plan rule, the session JSON, and is it legit

What SuperGrok costs: SpaceXSI’s price and ours

SpaceXSI lists SuperGrok at $30 a month, before any foreign-card fees and taxes. Our price is above that list price; the difference pays for not needing a card SpaceXSI will accept, paying in USDT, getting the plan on your own account, a format check before you pay, and human support. The official pricing page (read 2026-10-09) does not list a price for SuperGrok Heavy. Third-party reports commonly quote $300 a month, the launch price TechCrunch reported in July 2025; that is not a figure from the official pricing page.

Both plans are monthly, one month per order, with no annual option. Which tier suits you is covered in SuperGrok vs SuperGrok Heavy; paying with USDT step by step is in the USDT payment guide.

What you get: SpaceXSI’s own wording for SuperGrok and Heavy

These are the official plans, quoted from SpaceXSI’s pages as read on 2026-10-09 and re-read on 2026-10-11; what we sell is that same subscription on your account.

• Where Heavy comes from. TechCrunch reported that SuperGrok Heavy launched with Grok 4 in July 2025, with an early preview of Grok 4 Heavy; SpaceXSI describes Grok 4 Heavy as using parallel test-time compute to consider multiple hypotheses at once.
• Grok Bot is included in both. Grok Bot, SpaceXSI’s agent app, entered beta on August 11 and since August 26 has been included with SuperGrok, SuperGrok Plus and SuperGrok Heavy. It has its own usage, separate from your Grok plan, so work you hand to a Bot does not eat into your Grok allowance; usage resets weekly.
• Where Grok Bot runs. macOS, Windows, Linux, iOS, Android; install it and link your individual SuperGrok subscription. Getting started, and the reports about Claude Opus 5.5, are in Grok Bot and Claude Opus 5.5.
• The pricing page is the authority on models. As of our 2026-10-11 reading it lists the Grok 4.7 model for SuperGrok; through October 10 it listed Grok 4.6, and SpaceXSI published no separate announcement of the change. Grok 4.7 itself was released on September 21 and is also available in Cursor, Grok Build and the API. SpaceXSI decides plan contents and limits and may change them.

Account rules: free-plan accounts only

Sign in at grok.com, check the account’s current plan, and find your row:

The format check looks at the JSON’s format, not at your plan, so confirm the free plan yourself first; if you are unsure, ask the live chat before you pay.

How to copy the session JSON (desktop browser)

1. Open grok.com in a desktop browser and sign in to the account you want upgraded.
2. In a new tab of the same browser, open grok.com/api/auth/session; the page shows a block of JSON.
3. Press Ctrl/Cmd + A and Ctrl/Cmd + C, and paste it into the session field of the order form.

The form checks the format immediately. The usual messages:

• “This is a ChatGPT session”: you opened chatgpt.com’s session page; use grok.com/api/auth/session instead.
• “You pasted a Cookie-Editor array”: this product needs the JSON from the session page, not a cookie export.
• “Grok says you are not signed in”: the page does not say authenticated; sign in to grok.com in the same browser and open it again.
• “Could not be parsed” or “missing the account ID or email”: it was not copied in full; select all and copy again.

This is a format check, not a sign-in test. The JSON holds your sign-in status, account ID and email, with no login token; it tells us which account to upgrade. It is stored encrypted and cleared once the order is complete, and we never need your password. Paste it only into the order form, never into a chat.

How to buy SuperGrok with USDT (6 steps)

1. Check that the account is on the free plan: Sign in at grok.com and check the account’s current plan. It must be on the free plan: an account with an active SuperGrok, SuperGrok Plus or SuperGrok Heavy subscription cannot be topped up or renewed early.
2. Pick the product: On the pricing page choose SuperGrok or SuperGrok Heavy as a top-up on your own account and check the price.
3. Copy your session: In a desktop browser, sign in to grok.com, then open grok.com/api/auth/session in the same browser and copy all of the JSON on the page (Ctrl/Cmd + A, then Ctrl/Cmd + C). No password is needed.
4. Paste it into the order form for a format check: Paste it only into the order form, never into a chat window. The form checks the format: signed in, with an account ID and an email. If the format is wrong, it tells you why and you are not charged.
5. Pay in USDT: Choose TRC20 or BEP20 and send exactly the USDT amount shown; the quote is valid for 3 hours, the amount identifies your order, and payment is confirmed automatically.
6. Wait for activation and check: After payment our team activates the plan on that account by hand; we do not promise a fixed time. Then sign in at grok.com and confirm the plan. The session JSON is stored encrypted and cleared once the order is complete. Contact the bottom-right live chat promptly if anything goes wrong.

Ready? Order SuperGrok, 44.57 USDT. Want the top tier? Order SuperGrok Heavy, 297.92 USDT. New to USDT? You will need a wallet or exchange that can send USDT on TRC20 or BEP20.

After activation: check the plan and start Grok Bot

1. Plan: sign in at grok.com and confirm the account shows SuperGrok or SuperGrok Heavy.
2. Grok Bot: install it on macOS, Windows, Linux, iOS, Android and link your individual SuperGrok subscription; Bot usage is separate from Grok chat and resets weekly.
3. End date: note it. Each order covers one month and cannot be renewed before it ends.
4. One person, one account: the plan is on your own account; do not lend or split it.

Renewals: a new order after the month ends

• No early renewal: while the plan is active the account is not on the free plan, so it cannot be ordered.
• After it ends: place a new SuperGrok or SuperGrok Heavy order for the same account at the then-current price, with a freshly copied session that is format-checked again.
• Month by month: Heavy in busy months, SuperGrok in quiet ones; decide each time the month ends.

Is it legit? What we commit to, and what we cannot promise

What we commit to:

1. Format check before you pay. If the session format is wrong, the order form says why and you are not charged.
2. Your own account. The plan goes on the Grok account you submitted, not a shared one, and your chats stay where they are.
3. Session encrypted and cleared. It is cleared once the order is complete, and we never need your password.
4. Human support. Contact the bottom-right live chat promptly if anything goes wrong, or message Telegram @ccnb1937.
5. Track record. ClaudeMax has operated since November 2024 and has served more than 20,000 users (our own figure).

What we cannot promise:

• We are not SpaceXSI. ClaudeMax is independent: not SpaceXSI (xAI), and not an authorized reseller.
• SpaceXSI sets the plan contents. Limits, models and features can change; Grok Bot, for example, only joined SuperGrok on August 26. The official pages are the authority.
• No fixed activation time. Activation is done by hand after payment; ask the live chat about progress at any time.
• Prices are not fixed forever. They follow cost and exchange rates; the pricing page is authoritative.
