Pay for Claude & GPT API with USDT
byesu is an AI API gateway with native USDT top-up support — you can fund your account on-chain and immediately call Claude, GPT-5.6, Gemini, Grok, plus image and video models, all with one API key. Top up with USDT, Alipay or WeChat Pay; there is no subscription and no card on file. This makes byesu a practical option for developers who don't have an international credit card, or who simply prefer settling in stablecoins.
Why Pay with USDT
- No credit card required — fund your balance directly from any wallet or exchange that can send USDT.
- Fast settlement — balance is credited automatically after on-chain confirmation, usually within minutes.
- Pay-as-you-go — your balance is only spent on the tokens, images or video seconds you actually use. No recurring charges, no auto-renewal.
- One balance, every model — the same balance covers Claude, GPT-5.6, Gemini, Grok and all media models.
Supported Networks
USDT top-ups run on byesu's own payment system (no third-party payment processor between you and the gateway). Commonly used networks such as TRC20 (TRON) and BEP20 (BSC) are available; the authoritative list of supported networks is shown at checkout, together with the deposit address and exact amount for your order.
Send on the network shown
Always send USDT on the same network the payment page displays. Transfers sent on a different network cannot be matched to your order and may be unrecoverable.
How to Top Up with USDT
The flow takes about two minutes end to end:
- Sign in to the console — create an account first if you don't have one.
- Open the Top Up page from the sidebar and enter the amount you want to add.
- Choose USDT as the payment method and confirm. A payment page opens showing the network, a deposit address (with QR code), the exact amount to send, and a countdown timer.
- Send the exact amount from your wallet or exchange to the address shown, on the network shown, before the countdown expires.
- Wait for confirmation. Once the transaction reaches the required number of on-chain confirmations, your balance is credited automatically — no ticket, no manual review.
Arrival Time & Things to Check
- Confirmations, not instants. Crediting waits for on-chain confirmations. On most networks this means a few minutes; during network congestion it can take longer. The payment page tracks the status for you.
- The amount must match exactly. Each order is identified by its precise amount. Send the exact figure shown on the payment page — if you withdraw from an exchange, account for the withdrawal fee so the amount that arrives equals the order amount.
- Respect the countdown. Orders expire when the timer runs out. If that happens, start a new top-up order rather than sending to the old address; the old amount will no longer match anything.
- One transfer per order. Don't split an order across multiple transactions.
If a payment doesn't credit within a reasonable time and the transaction is confirmed on-chain, contact support through the console with the transaction hash.
How Billing Works After You Top Up
byesu is strictly pay-as-you-go: your balance is drawn down per request, and the console logs the actual charge for every call.
- Text / coding models (Claude, GPT-5.6, Gemini, Grok…) are billed per token with transparent multipliers — the console shows your live billed price next to the official list price. Cache hits on Claude models bill as low as 0.1x.
- Image models are billed per image, and video models per second — with automatic refunds on failed tasks:
| Model | Type | Price |
|---|---|---|
| gpt-image-2 | Image | $0.01 / image |
| nano-banana-2 | Image | $0.025 / image |
| firefly-gpt-image-2 | Image | $0.04 / image |
| seedream-4.5 | Image | $0.05 / image |
| firefly-video | Video | $0.015 / second |
| veo-3.1 (gemini-veo31) | Video | $0.01875 / second |
| runway-gen4-turbo | Video | $0.025 / second |
Full details, including how multipliers and token groups work, are on the Pricing & Billing page.

FAQ
Can I pay for the Claude API with USDT?

Which USDT networks are supported?
Commonly used networks such as TRC20 (TRON) and BEP20 (BSC) are available. The authoritative list is shown at checkout — the top-up page displays the networks currently enabled, along with the exact deposit address and amount for your order.
How long does a USDT top-up take to arrive?

Can I get a refund?
Failed image and video generation tasks are refunded to your balance automatically. For questions about remaining balance or a specific top-up, contact support through the console.
