How to Get a DeepSeek API Key — Complete Guide for Overseas Users (2026)

DeepSeek has become one of the most popular LLM providers in 2026 — and for good reason. Their V4 Flash model delivers GPT-5-class performance at a fraction of the cost. But if you are a developer outside China, getting a DeepSeek API key comes with a frustrating hurdle: the official signup requires a Chinese phone number.

This guide covers every working method to get a DeepSeek API key from overseas, from the official route (with a Chinese number) to the easiest alternative.

Method 1: Official DeepSeek Signup (Requires Chinese Phone)

If you have access to a Chinese phone number, the official path is straightforward:

Go to platform.deepseek.com
Click "Sign Up" — enter your email and set a password
SMS verification — you receive a verification code via SMS to your Chinese phone number
Log in to the dashboard — once verified, you land on the DeepSeek console
Create an API key — navigate to "API Keys" tab and click "Create API Key"
Copy the key — the key starts with sk-. Save it immediately

Pricing (after free credits run out):

Model	Input (per 1M tokens)	Output (per 1M tokens)
DeepSeek V4 Flash	$0.14	$0.42
DeepSeek V4 Pro	$0.58	$1.74
DeepSeek V3	$0.27	$1.10
DeepSeek R1	$0.55	$2.19

The official API also offers cache hit pricing — if your prompt matches a cached prefix, you pay only $0.014/M input tokens, a 90% discount.

Limitations for overseas users:

❌ Signup requires a Chinese phone number
⚠️ API may be slow or blocked from certain regions
⚠️ Customer support is in Chinese

Method 2: Via TokenPAPA (No Chinese Phone, Works Anywhere) ✅ Recommended

TokenPAPA is the easiest way for overseas developers to access DeepSeek models. No Chinese phone number, no VPN, no geo-restrictions.

Step 1: Sign Up

Go to tokenpapa.ai and create an account with your email. Verification takes about 30 seconds. Free credits are added immediately — no credit card needed.

Step 2: Get Your API Key

From the dashboard, click "Create API Key". Copy the key — this single key works with DeepSeek, Qwen, GPT-5, Claude, and every other model on the platform.

Step 3: Make Your First API Call

TokenPAPA uses the OpenAI-compatible format, so your existing OpenAI SDK code works with a simple base_url change:


client = openai.OpenAI(
    base_url="https://api.tokenpapa.ai/v1",
    api_key="your-tokenpapa-key"
)

# Call DeepSeek V4 Flash
response = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "What models do you support?"}
    ]
)
print(response.choices[0].message.content)

Or with curl:

curl https://api.tokenpapa.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-tokenpapa-key" \
  -d '{
    "model": "deepseek-v4-flash",
    "messages": [{"role": "user", "content": "Hello, DeepSeek!"}]
  }'

TokenPAPA Pricing

Model	Input (per 1M tokens)	Output (per 1M tokens)
DeepSeek V4 Flash	$0.14	$0.42
DeepSeek V4 Pro	$0.59	$1.77
DeepSeek V3	$0.27	$1.10
DeepSeek R1	$0.55	$2.19

Same prices as official DeepSeek — no markup on the models themselves. You pay the same rate but get:

✅ No Chinese phone number required
✅ Accessible from the US, Europe, Japan, anywhere
✅ No VPN needed
✅ English-language support
✅ One API key for 10+ model providers

Which Method Should You Choose?

Factor	Official DeepSeek	TokenPAPA
Chinese phone needed	✅ Yes	❌ No
Works from US/EU	⚠️ May be blocked	✅ Always
Signup time	2-3 minutes	30 seconds
Pricing	Same	Same (no markup)
Multi-provider	❌ DeepSeek only	✅ 10+ providers
Free trial	Limited free credits	Free credits on signup

If you already have a Chinese phone number and only need DeepSeek, the official route works fine. For everyone else — especially overseas developers — TokenPAPA is the fastest and most reliable option.
