Product details

This DeepSeek API key comes from a third-party gateway provider, not directly from DeepSeek. Each pack gives you a token allowance to call DeepSeek V4 Pro and V4.1 Flash through an OpenAI-standard base URL, so Cursor, VS Code, Codex, OpenCode or a Python script accept it right away. Tokens never expire, and you pay with crypto instead of topping up a DeepSeek account.

What's included

  • An API key, a base URL, a page showing remaining tokens and setup instructions
  • DeepSeek V4.1 Flash: for everyday chat, writing, code fixes and reading screenshots; the only model here that accepts images
  • DeepSeek V4 Pro: for harder problems such as agent planning, multi-file debugging and long reasoning
  • Both models offer a 1M-token context, up to 384K output tokens, tool calling, JSON output and thinking mode on by default

Which plan should I choose?

Usage is multiplied per model: V4 Pro counts at ×0.5 and V4.1 Flash at ×0.3. So one pack gives you about twice its size on V4 Pro and more than three times on Flash.

  • 10M tokens (about 20M on Pro / 33M on Flash): try Flash in Cursor for a few Q&A and bug-fix sessions.
  • 25M tokens (about 50M / 83M): a small project with V4 Pro planning and editing many files.
  • 50M tokens (about 100M / 167M): daily coding with Cline or Cursor for several weeks.
  • 100M tokens (about 200M / 333M): large repos or batch translation and summarization on Flash.
  • 500M tokens (about 1B / 1.67B): multiple repos or large data pipelines.
  • 1B tokens (about 2B / 3.3B): long-running agents and very high text volume.

Every pack includes both models. Larger packs cost less per million tokens.

Who it's for

  • Developers who want a strong, low-cost coding model in their IDE
  • Builders running batch translation, summarization or classification
  • Anyone who wants tokens that don't expire

How it works

  1. Choose a token pack.
  2. Pay with crypto via Cryptomus (USDT, USDC, BTC, ETH, LTC, TRX and more). Your order is confirmed automatically on-chain.
  3. Receive your key, base URL and setup guide by email, usually within 30 minutes during support hours (8:00–22:00 GMT+7). Setup help is available on Telegram.

Important notes

  • Third-party key, not an original DeepSeek key: it cannot log in to DeepSeek's platform or call DeepSeek's API endpoint directly. Do not send sensitive data through it.
  • No expiry: use tokens until they run out, then buy another pack.
  • Input and output tokens are multiplied by the model factor (V4 Pro ×0.5, V4.1 Flash ×0.3). There is no prompt caching, so each turn counts the full context again.
  • Warranty: if the key fails, we replace it or refund the unused tokens. Not covered: used-up tokens, misconfiguration, exceeding request limits or sharing the key.

Frequently asked questions

Is this an official DeepSeek API key?
No. It's a third-party key served through an OpenAI-compatible gateway with its own base URL.
Do the tokens expire?
No. Tokens have no expiry date; use them until they run out.
Why do I get more tokens than the pack size?
Usage is multiplied per model: V4 Pro counts at ×0.5 and V4.1 Flash at ×0.3, so a 10M pack gives about 20M tokens on Pro or 33M on Flash.
Which model should I use?
V4.1 Flash for everyday tasks and images; V4 Pro for complex agent planning, multi-file debugging and long reasoning.
What does the warranty cover?
If the key fails, we replace it or refund unused tokens. Misconfiguration, rate-limit errors and key sharing are not covered.
How do I pay?
With crypto via Cryptomus, including USDT, USDC, BTC, ETH, LTC and TRX.
