Quick Start — 3 Lines of Code

Replace your OpenAI base_url with TokenEase. Same SDK, same format, instant access to DeepSeek V4.

from openai import OpenAI

client = OpenAI(
    api_key="your-tokenease-key",      # Get free at tokenease.io/register
    base_url="https://tokenease.io/v1" # One endpoint, all models
)

response = client.chat.completions.create(
    model="deepseek-v4-pro",           # or deepseek-v4-flash
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Explain quantum computing in simple terms."}
    ],
    stream=False

Key Features

1M Token Context

Process entire codebases, long documents, or multi-turn conversations without truncation. 1M context is standard on all V4 models.

Thinking Mode

Enable step-by-step reasoning with adjustable effort (high/max). Perfect for math, coding, and complex problem solving.

Tool Calls & JSON Output

Build agents with function calling. Get structured JSON responses for reliable downstream processing.

No China Registration

DeepSeek direct API requires Chinese phone verification. TokenEase removes this barrier — sign up with any email.

Agent-Optimized

DeepSeek V4 is tuned for Claude Code, GitHub Copilot, OpenCode, and other agent frameworks. Drop-in replacement.

Free Trial

1 million tokens, 14 days, no credit card. Test V4 Pro and V4 Flash before committing to a paid plan.

Frequently Asked Questions

What model name should I use?

Use deepseek-v4-pro or deepseek-v4-flash in your API calls. The legacy names deepseek-chat and deepseek-reasoner are still supported but route to V4 Flash variants.

Do I need a Chinese phone number?

No. DeepSeek's official API requires China registration. TokenEase proxies requests through our verified account, so you only need an email address.

Is pricing the same as DeepSeek direct?

Yes — we pass through DeepSeek's pricing with zero markup. You get the exact same per-token rates.

Can I use the OpenAI SDK?

Yes. TokenEase is fully OpenAI-compatible. Change the base_url to https://tokenease.io/v1 and it works with the official openai Python/Node.js SDKs.

What is the context limit?

All DeepSeek V4 models on TokenEase support 1 million tokens of context — enough for entire books, large codebases, or hundreds of message threads.
