NovaBuy DeepSeek API With USDT: No Card, No Chinese Account
If your card gets declined by every AI provider and you already hold USDT, this is the shortest path: send crypto, get an OpenAI-compatible DeepSeek endpoint. No bank, no card, no Chinese account.
Why people end up searching for this
The usual story: you have a working card, it gets declined for an AI API because the provider only takes cards issued in a handful of countries, or because the charge is recurring and your bank blocks those by default. Meanwhile you already hold USDT — or can buy it in ten minutes locally — and you just want to pay for tokens.
DeepSeek's own platform doesn't solve this. Registration and billing assume a Chinese payment method, so for most of the world it's a dead end even though the models are cheap.
What buying with crypto actually looks like here
Step 1. Create an account at api.lbase.com/register. Email and password only. You get $1 of free credit, which is enough to test latency and output quality before you spend anything.
Step 2. Create an API key in the console. Pick a group when you do — a key without a group returns "API Key is not assigned to any group" on every request, and that error has confused a lot of people into thinking the service was down.
Step 3. When the free credit runs out, create a top-up order and choose USDT. Minimum is $5. You'll get a TRC20 address and a 30-minute window.
Step 4. Send USDT from whatever wallet or P2P desk you already use. One transfer, inside the window.
Why TRC20 specifically
TRON's USDT is the cheapest and fastest rail that almost every exchange and P2P desk supports. A transfer typically costs around a dollar and confirms in under a minute. ERC20 costs multiples of that, and on a $10 top-up the fee is a meaningful percentage of what you're buying.
What the crypto route actually costs
The token price is the smallest line in the bill. Two things decide the rest:
| Top-up size | TRC20 network fee | Fee as % of the top-up |
|---|---|---|
| $5 | ~$1 | 20% |
| $10 | ~$1 | 10% |
| $50 | ~$1 | 2% |
| $100 | ~$1 | 1% |
The network fee is roughly flat, so one larger top-up is far cheaper than several small ones. If you're still testing, $10 is the right call. If you already know you'll burn about $50 of tokens this month, send $50 once rather than five separate $10 top-ups and keep the ~$4 difference.
PayPal behaves the other way round: its conversion markup is proportional (roughly 4%), so it's about $0.40 on $10 and about $4 on $100. Neither is "better" — flat fees favour larger top-ups, proportional fees don't care.
Where to get USDT in ten minutes
Most of the countries our users come from have a local P2P market: Indodax or Pintu in Indonesia, Binance P2P in Nigeria and Vietnam, and equivalents elsewhere — check what actually operates where you are. You buy USDT with a local bank transfer or e-wallet, then either withdraw to a TRC20 wallet or send straight to the address shown on the order page if your desk supports TRC20 withdrawals. Keep a couple of dollars spare for the network fee.
The order window is 30 minutes, so it's worth having the USDT in hand before you create the order rather than starting the P2P purchase afterwards.
If you'd rather not touch crypto at all, PayPal also works.
What you're actually buying
An OpenAI-compatible endpoint that serves DeepSeek's current models — deepseek-v4-pro and deepseek-flash (V4.1). You point your existing client at our base URL and change nothing else. There's also an Anthropic-compatible endpoint for Claude Code and the Anthropic SDK.
It works with Cursor, Cline, Aider, Continue, Dify, LangChain, Cherry Studio and Open WebUI out of the box; the docs have copy-paste configs for each.
The honest part
We are a reseller, not DeepSeek. If you have a direct payment route to DeepSeek, that is cheaper — take it. We sell access for people who can't get one.
We run one production node in Hong Kong. There is no SLA, and we publish no availability percentage rather than a figure we have not measured.
We don't store your prompt contents beyond what billing and abuse prevention require.
Frequently asked questions
Which crypto network should I use?
TRC20 (USDT on TRON) — the fee is low and fixed at roughly $1 per transfer, and confirmation is fast enough for a top-up flow. Send on the wrong network and the funds do not arrive; match the network shown on the order screen exactly.
My transfer arrived but the balance did not update. Why?
In almost every case the order and the transaction did not meet. Create the order first and then send. Send a single transaction, not several — only the first is matched automatically to an order. Complete it inside the 30-minute window before the order expires. If funds still are not credited automatically, keep the transaction hash and ask for it to be processed manually; balances are recorded for what actually arrived on-chain, so a withdrawal fee deducted by an exchange does not make the difference disappear.
Is paying with crypto more expensive than a card?
Not usually, once you count the whole cost. A card adds a foreign transaction fee and a currency conversion spread. A TRC20 transfer is about $1 flat, which is about 1% on a $100 top-up — cheaper than most card spreads at that size, but about 20% if you top up only $5 at a time (about 10% at $10). Top up in larger, less frequent amounts.
Is a crypto payment private?
A blockchain transfer is public by nature. What it is not is a bank-controlled channel, which is the property that matters here: nobody can refuse the payment because of your country, your bank or your card issuer.
