Paste your OpenRouter payment link into ROZO Checkout, pick the coin and network you will withdraw from KuCoin, and ROZO shows a one-time deposit address with the exact amount. Withdraw from KuCoin to that address. When the transfer lands, ROZO pays the original OpenRouter invoice for you.
Which KuCoin network to pick
KuCoin's public currency data (checked 1 November 2026) lists these withdrawal networks that ROZO also accepts. Fees change, so read the fee on KuCoin's withdrawal screen before you confirm.
| Coin and network on KuCoin | KuCoin fee | KuCoin minimum |
|---|---|---|
| USDT on Polygon | about 0.8 USDT | about 1.6 USDT |
| USDC on Polygon | about 0.21 USDC | about 0.3 USDC |
| USDC on Base | about 0.5 USDC | about 1 USDC |
| USDT on Solana | about 1.5 USDT | about 3 USDT |
| USDT or USDC on Arbitrum | about 1 | about 5 |
| USDT on BNB Chain (BEP20) | about 1 USDT | about 10 USDT |
| BTC over Lightning | about 0.00002 BTC | about 0.00004 BTC |
Polygon is usually the cheapest choice for small top-ups. Note the 10 USDT minimum on BNB Chain. KuCoin also lists Ethereum, but its fee there is several dollars, too much for a small payment.
Step by step: KuCoin to OpenRouter credits
- In OpenRouter, open Settings then Credits, turn on the crypto option, enter the amount and click Purchase. Copy the payment link it generates.
- Open checkout.rozo.ai, paste the link, and pick the same coin and network you will use on KuCoin, for example USDT on Polygon. ROZO shows a one-time deposit address and the exact amount to send.
- In KuCoin, open Withdraw, choose the coin, paste the ROZO address, and select the matching network.
- Make sure the amount that arrives equals the amount ROZO shows. KuCoin shows its fee before you confirm.
- Confirm the withdrawal. Once the transfer lands, ROZO settles the OpenRouter link. The ROZO payment page shows live status until it does.
Recipient details for EU accounts
KuCoin's EU terms say it collects sender and recipient details for transfers under the EU transfer of funds rules, and it may reject or hold a transfer when those details are incomplete. If KuCoin asks who owns the address, answer truthfully: it is a payment address of a third party service, not your own wallet. If KuCoin will not send to it, withdraw to a wallet you control first and pay the ROZO address from there.
Three mistakes that cost money
Network mismatch: the network you pick in KuCoin must be the same one you picked on the ROZO page. Check the selector before you confirm.
Short amount: the amount that arrives must equal the amount ROZO asked for. If KuCoin takes its fee out of the amount you type, add the fee on top.
Sending late: a one-time deposit address belongs to one quote and expires with it. If the withdrawal is held and the ROZO window is about to run out, get a fresh quote instead of sending late. Never reuse a deposit address from an earlier attempt.
Memo or tag: deposits to ROZO on Solana, BNB Chain, Polygon, Arbitrum, Base and Ethereum do not use one. Leave that field empty.
What it costs
Three fees, each shown before you pay:
- OpenRouter's own crypto fee, around 5% as listed on OpenRouter's FAQ at the time of writing, is already inside the payment link amount.
- ROZO charges a 1% service fee, shown before you send anything.
- KuCoin charges its own withdrawal fee, shown on its withdrawal screen.
ROZO is independent and is not affiliated with OpenRouter, Coinbase or KuCoin. There is no ROZO account, no card and no KYC form on our side. Whatever checks KuCoin applies to withdrawals still apply.
