DDS Hub is a developer-first API relay platform that gives Chinese developers low-latency access to Anthropic and OpenAI models via a single Base URL.
What is DDS Hub?
DDS Hub (ddshub.cc) is a relay service that sits between developers and the official Anthropic/OpenAI APIs. It accepts API requests from tools like Claude Code, forwards them through encrypted tunnels to the original model providers, and returns the responses — with no bans, no timeouts, and a claimed added latency under 50 ms. The service is built for developers in China, supporting Alipay and WeChat Pay for purchases, and claims to be trusted by 2,000+ engineers. Input: any OpenAI- or Anthropic-compatible API request (e.g., chat completions, model listings). Output: the raw model response, unchanged.
Key Features
- Pure Relay — Requests are streamed directly to Anthropic via encrypted tunnels; the service claims it never logs your code or prompts.
- Low Latency — Globally distributed edge nodes keep added latency to under 50 ms compared to a direct connection; an example shows 32 ms latency to Hong Kong.
- Real Pricing — 100% official tokens with no hidden multipliers or "credits"; you pay official API usage fees plus a plan fee.
- Zero Markup on Token Costs — Both Claude Pro Developer and GPT Pro Developer plans pass through official Anthropic/OpenAI token prices with 0% markup.
- Unlimited Bandwidth — Both paid plans include unlimited bandwidth and priority edge routing.
- Alipay / WeChat Pay — Chinese developers can pay without a foreign credit card, unlike typical VPN workarounds.
- Day-1 Model Support — New Claude models are supported on the relay from the day of release, per the FAQ.
- Team Sub-accounts — Personal and team sub-accounts are included in the paid plans.
Who is it for?
- Chinese developers using Claude Code — Swap the ANTHROPIC_BASE_URL to https://www.ddshub.cc and start coding with full streaming support, without VPN instability.
- Developers building on GPT/Codex — Access the Codex GPT-5.5/5.4 series through an OpenAI-compatible relay, paying in RMB.
- Teams needing stable API access — The enterprise static IP pool is claimed to be ban-proof, avoiding the frequent IP-change bans seen with DIY VPN proxies.
- Cost-sensitive developers — The 1:1 RMB:USD pricing and 0% markup on token costs make official API usage affordable without foreign credit cards.
What can you do with DDS Hub?
- Claude Code integration: Set ANTHROPIC_BASE_URL and ANTHROPIC_API_KEY as shown in the docs, then run the claude command — your session uses DDS Hub as the relay.
- API testing: Use curl -I https://www.ddshub.cc/v1/models to verify connectivity; the example returns HTTP 200 with an x-region: ap-east-1 (Hong Kong) header.
- Team operations: Share the relay through personal/team sub-accounts while billing stays in RMB via Alipay or WeChat Pay.
Pricing
- Free tier: "Start for free" is mentioned, but details aren't shown.
- Claude Pro Developer: 1:1 RMB:USD exchange rate + official usage fees. Includes 0% markup on token costs, unlimited bandwidth, priority edge routing, Alipay/WeChat Pay, and sub-accounts.
- GPT Pro Developer: Same structure for OpenAI models.
- Both plans are marked "Recommended" on the page — actual RMB amounts are not disclosed.
FAQ
Which models are supported?
DDS Hub supports the Claude Sonnet / Opus / Haiku family and the Codex GPT-5.5 / 5.4 series. It stays in sync with the latest models released by the original providers, so new Claude models are available Day 1.
How is this different from the official Claude?
Requests are relayed directly to the official endpoints with no prompt logging, so you get the full, unaltered original-model experience. The relay adds a static IP pool and low-latency edge network instead of you having to manage VPN proxies.
What is the Base URL / API endpoint?
Use https://www.ddshub.cc as the Base URL for all API requests. For Claude Code, set ANTHROPIC_BASE_URL to this value and use your DDS Hub API key.
How does billing work?
DDS Hub mirrors the official providers' billing logic, including cache write and cache read charges. The exchange rate is fixed at 1:1 RMB:USD on paid plans, and token costs are passed through with 0% markup.
Is there a free tier?
The page says "Start for free," but no quotas or limitations are listed. Paid plans start with the Claude/GPT Pro Developer tiers, which require a plan fee plus official usage.
