State the pass you want (Starter, Pro or Fair-use Unlimited) and the currency (SOL or USDC). Have a referral code? Mention it in your request: the referrer earns 20%, one month at a time, renewed by each payment.
2. Pay the exact amount to the services wallet, with the memo 441:<order-id> in the transaction:
Memo: 441:P7-XXXXX
3. Receive your key. As soon as the payment is confirmed (finalized on-chain), the pass key is issued automatically by our payment watcher and delivered by reply email. It works on all 7 services with the x-api-key header. Keep it secret: it carries your credits.
30-day prepayment: crypto has no automatic billing — renewing means a new payment. Every payment is covered by our written guarantee.
