How it works
Three steps, no code, no coupon
The bonus is applied automatically to your account the moment your first payment clears. Nothing to redeem, nothing to enter at checkout.
02
Make your first top-up
Top up any amount. The matching credit lands in your balance immediately, capped at $100.
03
Call any model
Keep your existing SDK and base URL. Bonus credit is consumed first, at discounted rates.

The rules
What the offer covers
Six things worth knowing before you top up. No hidden conditions beyond these.
All accounts, once
Available to every HiLinkUP account on the first top-up only. Later top-ups do not generate further bonus credit.
1 : 1, same currency
Bonus credit equals your top-up amount, in the same currency and unit as the payment.
Max $100 bonus
The bonus never exceeds $100 per account. Anything you add above $100 in your first top-up earns no extra credit.
30 days from issue
Bonus credit expires 30 days after it is issued. Unused bonus is forfeited at expiry and cannot be cashed out or extended.
Bonus is spent first
When both bonus and paid balance exist, bonus credit is consumed first — so the portion closest to expiry gets used before it lapses.
Discounted rates apply
Bonus credit is charged at the discounted model price, not the list price. If a model is 50% off, calls made with bonus credit are billed at that same 50% rate.

Prices in USD. Bonus credit is denominated in the currency of your top-up.
FAQ
Things people ask before topping up
What happens to bonus credit I do not use?
It expires 30 days after issuance and the unused remainder is forfeited. It cannot be refunded, cashed out, or moved to another account. Plan around it: bonus credit is best spent on high-volume, low-cost calls.
Can I stack the bonus across several top-ups?
No. The bonus applies once, to the account's first top-up, and is capped at $100 no matter how many payments you make.
Does my paid balance expire too?
No. Balance you paid for stays on your account indefinitely. Only the bonus portion carries the 30-day window.
Is bonus credit billed differently from paid balance?
No difference in price. Bonus credit is metered at the same discounted model rates as everything else — a model at 50% off costs the same per token whether it is paid from bonus or from balance.
Can I withdraw or transfer bonus credit?
No. Bonus credit is usable only for model calls on the account it was issued to. It cannot be withdrawn, transferred, or invoiced.
How long is the offer running?
It is ongoing from publication. If the terms change, we will announce the change on this page before it takes effect.
Do multiple accounts count as separate first top-ups?
They are not intended to. Accounts created in bulk to claim the bonus repeatedly may have their bonus credit revoked.
