These are the tools we use ourselves to consume DeepSeek, Qwen, Kimi, GLM, Doubao, and other Chinese LLM APIs from outside mainland China. Each section solves one concrete blocker — Chinese-language docs, failed credit-card checkouts, BYOK editor integration, API debugging, or reliability under endpoint outages.

Read Chinese provider docs, onboarding pages, and PDFs with inline CN→EN translation. Every Chinese LLM API sign-up uses at least one of these.
by Immersive Translate
Inline bilingual translation on every page, including Chinese LLM docs + PDFs.
The de-facto standard among Chinese-speaking developers translating English tech content — and it's equally useful in the other direction. Open DeepSeek / Moonshot / Zhipu / Qwen docs with this installed and you get side-by-side English alongside the original Chinese instead of the clumsy Google Translate page-replace view. Supports DeepL + Gemini + Claude as translation backends for better quality than Google.
Fund Chinese LLM API accounts from abroad when your credit card fails at checkout. Usually the most frustrating blocker on day one.
by Wise
Multi-currency account with near-interbank exchange rates, including CNY.
Most Chinese LLM billing portals reject foreign credit cards outright. Wise lets you hold a real CNY balance at mid-market rates, then top up DeepSeek / Kimi / Zhipu / Baichuan through Alipay. Also useful for paying Volcengine-Doubao (ByteDance) invoices without a Chinese entity. The alternative — find a friend in China to top up and reimburse — doesn't scale.
AI-assisted editors that support Bring-Your-Own-Key for OpenAI-compatible Chinese providers. Drop DeepSeek / Qwen / GLM in as the agent model with no middleware.
by Anysphere
AI editor with BYOK — point its agent at DeepSeek, Qwen, or any OpenAI-compatible endpoint.
Cursor's Settings → Models → OpenAI Base URL field accepts any custom host. Configure `https://api.deepseek.com/v1` + your DeepSeek API key and Cursor's agent runs against DeepSeek V3 at ~1/15th the cost of GPT-4o. Same pattern works for DashScope International (Qwen) and Zhipu. First demonstration most developers need to take Chinese LLMs seriously.
HTTP clients for debugging signed requests, streaming SSE responses, and authoring the first /v1/chat/completions call against a Chinese endpoint.
by Postman
The default HTTP client for authoring, streaming, and saving Chinese-endpoint API requests.
Chinese provider docs usually show curl first. Paste the curl into Postman, swap in your key, save the request to a collection, and you have a reusable harness for every /v1/chat/completions variant. SSE streaming support makes it straightforward to verify token-by-token responses before writing client code. Free tier is enough for the kind of one-off probing this workflow needs.
Put a retry + cache + fallback layer in front of the Chinese endpoint so a transient 502 doesn't take down your agent. Single most impactful reliability upgrade.
by Cloudflare
Free gateway that adds retry + cache + observability to any OpenAI-compatible endpoint.
Chinese endpoints have occasional 5xx storms during China business hours. Put Cloudflare AI Gateway in front and transient failures auto-retry, repeated prompts hit a cache (cutting DeepSeek bills ~30% on agent workloads), and you get per-request logs that make debugging a flaky production agent dramatically easier. Free tier covers most hobbyist / startup usage. Ships with a single base-URL swap.
by Portkey
AI Gateway with explicit cost control, prompt versioning, and multi-provider fallback.
Portkey lets you set a fallback policy like 'try DeepSeek first, if fails within 2s fall back to Together.ai hosted DeepSeek, then fall back to GPT-4o-mini' — encoded as a YAML. On top of that, prompt versioning + per-customer usage budgets make it the pragmatic choice when you're running a production agent that needs to survive CN endpoint hiccups. Paid tiers from $49/mo; free tier is enough to evaluate.
What's missing from this list?
We keep the toolkit deliberately small — adding tools only when they solve a real blocker we've hit ourselves accessing Chinese LLM APIs. If you're stuck on something this list doesn't cover, email us via the contact in About. We won't publish your name; we'll just add the tool if it's genuinely useful.
