DeepSeek V4 is incredible value. But the official platform won't take my credit card. Here's how I fixed it.
The problem
DeepSeek V4-Flash is roughly $0.14 per million input tokens from the official API — a fraction of what OpenAI or Anthropic charge. It supports an OpenAI-compatible endpoint, so in theory you can drop it into any existing project.
There's just one catch: the official DeepSeek platform only accepts Alipay and WeChat Pay. If you're an international developer with a Visa or Mastercard, you literally cannot pay them.
I wanted to use DeepSeek for a project. I couldn't. So I built a proxy that accepts credit cards.
How it works
The stack is straightforward:
- LiteLLM — routes requests to DeepSeek, manages API keys and usage tracking
- Creem.io — payment processing (Visa, Mastercard, Apple Pay, Google Pay)
- PostgreSQL — stores key metadata and usage data
- Node.js/Express — auth, dashboard, key management
When you buy credits, the server calls LiteLLM's /key/generate to create an API key with a spending limit matching your purchase. The key works with any OpenAI-compatible SDK — just change base_url to https://api-hub.cc/v1 and you're set.
What DeepSeek V4-Flash offers
- Price. Flash input is ~$0.14/M tokens officially. Through api-hub.cc it's $0.20/M — slightly above raw cost, but you get instant provisioning, a dashboard, and credit card payment.
- Speed. Flash generates at 100+ tokens per second. In my experience it's faster than any Anthropic or OpenAI model I've used via API.
- OpenAI compatibility. Same endpoint format, same SDK. Zero code changes needed.
- Prompt caching. Cache hit pricing drops to $0.02/M for Flash — 10x cheaper than uncached input. Just keep your system prompt consistent.
An interesting development: peak pricing
In late June 2026, DeepSeek announced a peak/off-peak pricing model for V4 Flash. During Beijing peak hours (9:00-12:00 and 14:00-18:00), official prices double to ~$0.28/M input.
api-hub.cc charges a flat $0.20/M for Flash input at all hours — which means during peak times, the proxy is actually cheaper than going direct.
Current pricing
- Flash: $0.20/M input, $0.40/M output (cache hit: $0.02/M)
- Pro: $0.60/M input, $1.20/M output (cache hit: $0.15/M)
Three tiers: $5 (casual use), $20 (daily driver), $100 (team/power user).
Final thought
The only thing standing between most international developers and DeepSeek's pricing is a payment method. api-hub.cc solves that one problem — everything else (the speed, the quality, the OpenAI compatibility) is already there.
