How to Access Tencent Hunyuan Hy3 and DeepSeek V4 API Outside China (No +86 Phone Needed)

# Export APIVALE proxy base URL and API key
export ANTHROPIC_BASE_URL="https://apivale.com/v1"
export ANTHROPIC_API_KEY="sk-apivale-your-api-key"

# Launch Claude Code CLI with target model
claude --model deepseek-v4-flash

The release of state-of-the-art Chinese models like Tencent Hunyuan Hy3 (a Mixture-of-Experts model featuring 295B total / 21B active parameters under the Apache 2.0 license) and DeepSeek V4 has shifted the price-performance ratio for AI developer agents globally. These models deliver near-frontier reasoning depth, advanced coding proficiency, and robust tool-calling mechanics at a fraction of Western model costs.

However, global developers face a frustrating roadblock when trying to access them: official platforms require a Chinese (+86) mobile phone number for registration, mainland Chinese identity or corporate license verification, and local payment methods like Alipay or WeChat Pay.

In this guide, we walk you through how to bypass these registration barriers and integrate Tencent Hunyuan Hy3 and DeepSeek V4 into your stack in under two minutes using APIVALE. For the latest high-throughput multimodal setup and 437 t/s benchmarks, follow our dedicated DeepSeek V4.1 Flash API setup guide for Cursor & Claude Code.

Quick Start: Call Hy3 & DeepSeek V4 via APIVALE

You do not need a +86 phone number or a Chinese corporate ID. Simply register a free account on APIVALE and query the models via our unified, OpenAI-compatible endpoint:

curl https://apivale.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_APIVALE_KEY" \
  -d '{
    "model": "hy3-preview",
    "messages": [{"role": "user", "content": "Write a Node.js script to call an API."}]
  }'

Official Platforms vs. APIVALE API Bridge

Accessing these models through official developer portals compared to utilizing APIVALE’s proxy gateway highlights significant workflow simplifications:

Access Parameter	Official Tencent / DeepSeek Portals	APIVALE Gateway
Phone Verification	Chinese (+86) Mobile Required	Global Email or Google / GitHub OAuth
Payment Validation	Mainland Bank Cards, WeChat, Alipay	Waffo Global Billing (Credit Cards & Global Wallets)
KYC Requirement	Chinese National ID or Business License	None
API Format	Custom SDKs or Mainland Endpoints	Unified OpenAI-Compatible REST API
Edge Routing Latency	High (Routes through mainland gateway)	Low (Distributed global edge routing)

Model Pricing & Specifications (2026)

APIVALE operates a high-throughput tunnel directly to the nearest regional endpoints, passing through highly competitive official pricing without hidden markups:

Model ID	Input Price (per 1M)	Output Price (per 1M)	Context Limit	Primary Specialization
hy3-preview	$0.07	$0.26	128K	Agent workflows, coding, complex reasoning
deepseek-v4	$0.14	$0.28	64K	Cost-effective general reasoning & JSON outputs
deepseek-r1	$0.55	$2.19	64K	Deep chain-of-thought mathematical reasoning

Technical Integration: Python & TypeScript

Integrate Tencent Hunyuan Hy3 and DeepSeek V4 into your codebase with standard libraries. Ensure you handle gateway status codes properly in production.

1. Python Integration

First, install the official OpenAI Python package:

pip install openai

Then, initialize the client pointing to the APIVALE gateway:

import os
import openai
from openai import OpenAIError

# Initialize client pointing to APIVALE gateway
client = openai.OpenAI(
    base_url="https://apivale.com/v1",
    api_key=os.environ.get("APIVALE_API_KEY")
)

try:
    response = client.chat.completions.create(
        model="hy3-preview",
        messages=[
            {
                "role": "user", 
                "content": "Verify if this array is sorted: [1, 2, 4, 3]"
            }
        ],
        timeout=30.0
    )
    print("Response from Hy3:")
    print(response.choices[0].message.content)

except OpenAIError as e:
    # Error handling for network drops or unauthorized keys
    print(f"APIVALE Gateway Integration Error: {e}")

2. TypeScript/JavaScript Integration

First, install the OpenAI package:

npm install openai

Configure your script to query DeepSeek V4:

import { OpenAI } from 'openai';

const client = new OpenAI({
  baseURL: 'https://apivale.com/v1',
  apiKey: process.env.APIVALE_API_KEY,
});

async function queryModel() {
  try {
    const response = await client.chat.completions.create({
      model: 'deepseek-v4',
      messages: [{ role: 'user', content: 'Output the following JSON schema: { name: string, active: boolean }' }],
    });
    console.log("Response from DeepSeek V4:");
    console.log(response.choices[0].message?.content);
  } catch (error) {
    console.error('Failed to resolve request via APIVALE:', error);
  }
}

queryModel();

Developer FAQ

Q: Can I use standard OpenAI SDK wrappers to connect to these models?
A: Yes. APIVALE is fully OpenAI API protocol compliant. Simply change the client baseURL parameter to https://apivale.com/v1 and supply your APIVALE API key. All existing SDK properties (like stream, temperature, and max_tokens) will function as expected.

Q: Are there geographic restrictions on where I can call the API from?
A: No. Unlike Tencent Cloud and official DeepSeek endpoints, which enforce region-blocking or strict billing validations, APIVALE routes requests through global edge nodes. You can call the API globally (including from the US, UK, EU, and South Korea) without VPNs or proxy setups.

Q: How does APIVALE handle payment processing?
A: We use a global Stripe setup and cryptocurrency gateways. You can fund your account using any international Visa, MasterCard, or American Express credit card, bypassing Stripe declines common on US-centric aggregators. We also support automated USDT and USDC deposits.

Q: Is there a rate limit on the developer tier?
A: APIVALE offers custom and scalable concurrency tiers. By default, new accounts start with sufficient rate limits for prototyping (up to 200 RPM). If your agent fleet scales, you can request custom limits with no markup fees.
