AI API Relays That Accept USDT
69 relays listed
USDT is one of the most convenient ways to pay for international users, developers without a locally-issued card, and anyone who'd rather not tie a payment method to their identity. Every relay below accepts USDT, cutting out card-network friction entirely.
USDT top-ups usually clear across borders with no issue, but it's worth confirming the chain (TRC20 vs. ERC20) and the relay's on-chain confirmation time before you send anything.

How to choose one
Check whether the relay expects TRC20 or ERC20 — fees and confirmation times differ, and sending on the wrong chain can mean lost funds.
Crypto top-ups need on-chain confirmation, usually a few minutes — send a small test amount first.
USDT top-ups don't require tying a payment method to your real identity, which some developers prefer.
Frequently asked questions
Why pay for an API relay with USDT?
It's the most practical option for international users, cross-border payments, and anyone who'd rather not use a card tied to their identity — no local payment method needed.
Which chain should I use for USDT top-ups?
TRC20 is the common low-fee choice; ERC20 also works at some relays. Always follow what the specific relay's payment page says, and double-check before sending to avoid losing funds on the wrong chain.
How long does a USDT top-up take to land?
It needs on-chain confirmation, typically a few minutes — send a small test amount the first time to confirm everything works.
