AI API Relays That Accept USDT

43 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.

Kantro

Kantro is a GPT and Claude API relay for developers (base URL https://kantro.dev/v1, OpenAI-compatible) priced at 40% of official per-million-token rates, e.g. Claude Opus 5 at $2/$10 and GPT-6 Astra at $4/$20, on prepaid USD credits. Its supply is pooled unused ChatGPT and Claude subscription capacity contributed by other users, so it is subscription resale rather than official API access; onboarding is capacity-gated (a limited "Founding 200" cohort at launch) and purchases are non-refundable. Payment is crypto only per the operator: USDT on Tron, Ethereum, BSC, Solana, TON and other networks, plus USDC, BTC and LTC, with no card support. Kantro states it does not store prompts or use them for training.

How to choose one

Confirm the chain

Check whether the relay expects TRC20 or ERC20 — fees and confirmation times differ, and sending on the wrong chain can mean lost funds.

Expect an on-chain wait

Crypto top-ups need on-chain confirmation, usually a few minutes — send a small test amount first.

A privacy-friendly option

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.
