Buy DeepSeek API access with crypto (USDT)

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 $2 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 $10. 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.

The amount you send is the amount you get. We credit the balance based on what actually lands on chain, so if your exchange skims a withdrawal fee and 9.4 USDT arrives instead of 10, you get $9.40 of balance — not a failed order and not a support ticket.

One rule that avoids most problems: don't split the payment into two transfers. Only the first transfer auto-matches to an order. Anything that lands outside the window we catch with on-chain monitoring and credit manually — email [hello@lbase.com](mailto:hello@lbase.com) with the transaction hash.

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.

If you'd rather not touch crypto at all, PayPal also works and there's a separate guide for that.

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 on a single node in Hong Kong. Treat uptime as best-effort and keep a fallback provider configured for anything production. For side projects, prototypes and learning, it's fine.

We don't store your prompt contents beyond what billing and abuse prevention require.
