How to Get Doubao API Key Without Chinese ID 2026

ByteDance’s Doubao Seed 2.0 has quickly become one of the most talked-about AI models in 2026. With code generation capabilities that surpass GPT-4o and Claude Opus, and multimodal performance that rivals the best models in the world, it’s no wonder developers are eager to get access.

Unfortunately, direct access to Doubao API via Volcano Engine requires a Chinese ID and Chinese phone number. But don’t worry – there are several reliable third-party API gateways that allow international users to access Doubao Seed 2.0 without any Chinese documentation.

In this guide, I’ll compare all the available options and show you exactly how to get started.

What is Doubao Seed 2.0?

Doubao Seed 2.0 is ByteDance’s latest flagship AI model, released in March 2026. It offers:

  • Superior code generation capabilities
  • Excellent multimodal understanding (images, audio, video)
  • 128k context window
  • Fast response times
  • Competitive pricing

Independent benchmarks have shown that Doubao Seed 2.0 outperforms GPT-4o in code generation, mathematical reasoning, and Chinese language tasks.

Before we get into the third-party options, let’s quickly cover direct access so you understand why it’s not suitable for international users.

Direct access to Doubao API is provided through ByteDance’s cloud platform, Volcano Engine. To sign up, you need:

  • A Chinese phone number
  • A Chinese ID card
  • A Chinese bank account or Alipay account

Unless you have all of these, direct access is impossible. Even if you do have a Chinese ID, the interface is entirely in Chinese with no English option.

For these reasons, I strongly recommend using a third-party gateway for international access.

EvoLink is the most popular and reliable third-party gateway for Chinese AI models. It was specifically created to give international developers access to models that are otherwise only available in China.

Code Example

EvoLink uses the OpenAI API format, so you can use the same code you would use for OpenAI or DeepSeek:

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_EVOLINK_API_KEY",
    base_url="https://api.evolink.ai/v1"
)

response = client.chat.completions.create(
    model="doubao-seed-2.0",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Write a function to sort a list in Python."}
    ]
)

print(response.choices[0].message.content)
