One API Key for DeepSeek & Qwen — No Credit Card, Just PayPal

#deepseek #api #opensource #ai

If you've been using LLM APIs lately, you've probably run into this situation:

DeepSeek requires a credit card and minimum deposit
Qwen/Alibaba requires a separate account
OpenRouter needs a card too
You end up with 5+ API keys spread across different providers

I built DeepRoute API to solve exactly this problem.

What DeepRoute Does

A single API endpoint, one API key, access to all major open-source models. 100% OpenAI SDK compatible — just change the base_url.

All models use pay-as-you-go billing — no monthly commitment, no surprises.

Quick Start

Python

from openai import OpenAI

client = OpenAI(
    base_url="https://deeproute-api.duckdns.org/v1",
    api_key="your-api-key"
)

# DeepSeek V4 Flash
response = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[{"role": "user", "content": "Explain quantum computing in 3 sentences"}]
)
print(response.choices[0].message.content)

cURL

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

Node.js (with streaming)

import OpenAI from 'openai';
const client = new OpenAI({
  baseURL: 'https://deeproute-api.duckdns.org/v1',
  apiKey: 'your-api-key'
});
const stream = await client.chat.completions.create({
  model: 'deepseek-v4-flash',
  messages: [{role: 'user', content: 'Write a haiku about APIs'}],
  stream: true,
});
for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta?.content || '');
}

Why Not Use the Official Providers?

Feature	DeepRoute	DeepSeek Official	OpenRouter
Credit Card Required	No	Yes	Yes
PayPal Accepted	Yes	No	No
Minimum Deposit	None	Yes	None
Single Key — All Models	Yes	No	Yes
Telegram Support	Yes	Ticket	Forum

The small premium over official pricing pays for convenience: no credit card, PayPal support, a single API key for all models, and direct human support on Telegram.

Why I Built This

I was tired of juggling multiple API keys and being forced to enter a credit card for every single AI provider. I wanted a simpler experience: one key, one endpoint, pay how I want.

DeepRoute started as a personal convenience layer and grew into a public service. It's built on One API — an open-source API gateway — running on a dedicated server.

Feedback?

I'm actively building this and would love to hear what models you'd like added or what features would make this more useful for you. Drop a comment below or reach out on Telegram!

Note: DeepRoute is a convenience relay — it adds a small markup over official prices in exchange for PayPal support, no credit card requirement, and a unified API for all models.
