DeepSeek API — Pay with Credit Card

Access DeepSeek V4-Flash & V4-Pro via credit card. Instant API key after purchase. English dashboard. OpenAI-compatible — just change your base URL.

Quick Start

Replace your existing OpenAI API base URL with ours. Your existing code works without any changes — just update the base_url and API key.

Python

from openai import OpenAI

client = OpenAI(
    base_url="https://api-hub.cc/v1",
    api_key="ah-your-key-here"
)

response = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[{"role": "user", "content": "Hello"}]
)
print(response.choices[0].message.content)

cURL

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

Node.js

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api-hub.cc/v1",
  apiKey: "ah-your-key-here",
});

const response = await client.chat.completions.create({
  model: "deepseek-v4-flash",
  messages: [{ role: "user", content: "Hello" }],
});
console.log(response.choices[0].message.content);

Models

Authentication

Include your API key in the Authorization header:

Authorization: Bearer ah-your-key-here

Get your API key from the Dashboard after purchase.

Available Endpoints

Streaming

We support Server-Sent Events (SSE) streaming. Use stream: true in your request:

stream = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[{"role": "user", "content": "Write a poem"}],
    stream=True
)
for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="")

Error Codes

Rate Limits

Default rate limit is 1000 requests per minute for Flash, 500 for Pro. Contact us if you need higher limits.

Cache Hint

DeepSeek automatically caches repeated prompt prefixes. To maximize cache hits and save costs:

• Put static content (system prompts, few-shot examples) at the beginning of your prompt
• Keep system prompts consistent across requests
• Cache hit input costs $0.02/M vs $0.20/M for uncached
