DeepSeek API in Vietnam: USDT or PayPal top-ups, no Chinese phone number

PayPal in Vietnam is easier for receiving money than for spending it, and local cards are frequently declined on foreign AI services. NovaAPI lets Vietnamese developers run DeepSeek V4 behind Claude Code, Cursor or their own app, topped up with USDT or PayPal.

Where Vietnamese developers get stuck

Practical routes

USDT (TRC20) — buy via a local exchange or P2P (Binance P2P is widely used in Vietnam), keep a few TRX for the network fee, and send the exact top-up amount to the address in your order. Credited at the on-chain amount.

PayPal — if your account can send international payments, this works too. Top-ups are one-off, not subscriptions, so you don't need recurring billing to succeed.

One transfer, inside the countdown. We credit what actually arrives on-chain — send $10 and receive $9.4 after a withdrawal fee and you simply have $9.40 of balance. But a transfer that arrives after the order expires isn't matched automatically; we catch it with on-chain monitoring and credit it manually (send us the tx hash).

What the bill actually looks like

WorkloadTokens (rough)Cost on DeepSeek V4 Flash
One Claude Code session20k in + 5k out$0.019
A day of heavy agent use400k in + 120k out$0.42
A small production app (10k requests/day, short prompts)~15M in + 2M outabout $11 / month

Compare that with $20/month per-seat coding assistants: at these token prices, pay-as-you-go is usually cheaper unless you're prompting all day every day.

Getting started (about 5 minutes)

  1. Create an accountapi.lbase.com/register. Email + password only; the $2 of free credit lands in your balance immediately, so you can test before paying anything.
  2. Create an API key — in the console, open API Keys → Create Key and pick a group (DeepSeek for native model names, Claude Compatible if you want to keep Claude model names). A key without a group cannot call anything.
  3. Point your tool at the endpointhttps://api.lbase.com/v1 for OpenAI-compatible clients, https://api.lbase.com for Claude Code / Anthropic SDK. Full copy-paste configs for Claude Code, Cursor, Codex CLI, OpenCode and the OpenAI SDK are in the docs.
  4. Top up when the free credit runs out — minimum $10, by PayPal or USDT (TRC20). Balance never expires.

What it costs (same price everywhere)

ModelInput / 1M tokensOutput / 1M tokensTypical use
DeepSeek V4 Flash$0.55$1.65everyday coding, agents, chat
DeepSeek V4 Pro$1.65$4.95hard reasoning, large refactors
Claude-compatible names$0.77 – $6.93(Sonnet→Opus tier)keep Claude Code unchanged

For scale: a typical Claude Code session burns 20k–60k input tokens and 3k–10k output tokens. On DeepSeek V4 Flash that is roughly $0.02–$0.05 per session — a $10 top-up covers hundreds of sessions.

Vietnam FAQ

Có cần thẻ tín dụng không?

Không. USDT (TRC20) hoặc PayPal đều được — minimum $10.

Do I need a Vietnamese company or tax code?

No. Accounts are individual — email plus password. If you need an invoice for a company, email us.

Which network for USDT?

TRC20 (TRON). Cheap and fast for small amounts; make sure you send on TRON, not BEP20 or ERC20.

Is Claude Code supported?

Yes — including with Claude model names. Create a key in the Claude Compatible group and point Claude Code at https://api.lbase.com; your existing Claude Code workflow stays unchanged.
