:fire: Unlimited FABLE 5.1 · OPUS 5.5 · GPT 6 ASTRA · GEMINI 4 ARGON - CHAT & $10 API credits for Codex, Claude Code & Cursor — the 5-minute trick nobody’s using

The trick in one line: Team Expert gives ∞ seats; each seat carries $10 of API credits; the checkout payment sits at “confirming” for days while the plan, credits and models are already live.
∞ seats × $10 = ∞ credits. ∞ accounts = ∞ credit.

The plan
:busts_in_silhouette: Seats ∞ (Team Expert)
:admission_tickets: Per seat $10 API credits
:stopwatch: Setup 5 minutes

What’s inside: one Mammouth login, four frontier models — Fable 5.1 and Opus 5.5 (Claude), GPT 6 Astra (OpenAI), Gemini 4 Argon (Google) —
and an OpenAI-compatible API for Codex, Claude Code & Cursor. You name it. :elephant:

:rocket: Setup, start to finish

  1. :globe_showing_europe_africa: VPN → any Europe country that supports SEPA (the EU direct-debit rail), e.g. Germany
  2. :e_mail: Sign up on mammouth.ai with a business email (not Gmail — this is the whole trick)
  3. :busts_in_silhouette: Pick the Team plan → Expert (the per-seat plan; each seat carries $10 of API credits)
  4. :plus: Add as many seats as you want (unlimited)
  5. :bank: Checkout with SEPA Direct Debit (the bank settles it after checkout)
  6. :1234: IBAN (the bank account number the debit is drawn from) → randomiban.com · Address → bestrandoms.com/random-address

:high_voltage: Why the window works

SEPA doesn’t verify anything at checkout. It just fires off a direct debit and lets you in immediately.
The payment is still “confirming” for days — meanwhile your plan is live, credits loaded, models unlocked. :collision:

Every seat = $10 in API credits. Seats are unlimited. Accounts are unlimited.

→ Unlimited accounts = unlimited credit. :money_with_wings:

Need a business email, any tricks?

A useful way to test this kind of multi-model setup is to start with one small, repeatable task and run the same prompt on two models, so you can compare accuracy and speed instead of judging by the marketing names. Before adding more seats, check the account dashboard for the actual credit balance and payment status, because a plan that only shows as confirming is not a reliable base for real work. Use an email address you actually control, preferably a work or school address if the plan requires one, so password resets and billing notices do not get lost. Keep API keys separate by project and rotate any key that was pasted into a shared test, since a single leaked key can drain credits across every model. If a payment will not go through, pause and sort out the billing details first rather than trying random payment details, because failed or disputed payments are the fastest way to lose access to the whole account.
