Searching "deepseek api" in English in 2026, most of the top SERP results are wrapper sites — resellers who put your prompts through their own DeepSeek key and charge a 2-10× markup. The actual DeepSeek platform isn't in the top 3. This post walks through the real signup flow and shows how to spot the wrappers.
DeepSeek is a Hangzhou-based AI company that publishes open-weight reasoning and chat models. Their hosted API sells inference at aggressive prices — DeepSeek V3 is $0.27 input / $1.10 output per 1M tokens, DeepSeek R1 is $0.55 / $2.19. Both are OpenAI-compatible.
The company that operates the API is DeepSeek (Hangzhou) Artificial Intelligence Co., Ltd.. Domain registered 2023; ICP 备案 under their corporate name. This matters because wrapper sites often register in a different jurisdiction (US / EU / BVI) without the ICP filing that a real Chinese LLM platform would have.

Sign-up flow works from outside China with no VPN required as of mid-2026.
curl https://api.deepseek.com/chat/completions \
-H "Authorization: Bearer YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{"model": "deepseek-chat", "messages": [{"role": "user", "content": "Hello"}]}'

Visual tells that a DeepSeek-branded site is a wrapper:
whois)deepseek-ai.com, deepseek-api.io, deepseekchat.xyz — the real one is platform.deepseek.comReal DeepSeek gives YOU an API key to use with your own billing; wrappers keep the key themselves and proxy your requests.
DeepSeek endpoints sometimes return 5xx during China business hours (model rollout / capacity spikes). If that matters for your use case, put Cloudflare AI Gateway in front — free, adds retry + cache + per-request logging with a single base-URL swap.
For production reliability you probably want a fallback like Portkey to route to Together.ai or Fireworks (which also host DeepSeek) if the primary endpoint misbehaves.
