}'Want Claude API? First passthese 3 hurdles
Overseas registration, unstable connections, payment friction — Anthropic hasn't fixed them. We did.
Account Rejected or Banned
Anthropic requires an overseas phone number and credit card. Accounts get banned arbitrarily and balances are unrecoverable.
Unstable Connection & Timeouts
Direct connections from China to Anthropic drop frequently. Too unreliable for production workloads.
Payment Friction
Official API only accepts foreign credit cards. No CNY payment, no corporate billing or invoicing.
One API Key,
UnlockAll Claude Models
We're not a multi-model aggregator. Every resource and optimization is focused on Claude, ensuring day-one model support and the deepest call optimization.
Direct
China Connection
Multi-node deployment — low latency, no drops, stable access without any proxy tools.
100% Compatible
with Official API
Fully compatible with the Anthropic SDK. Just replace base_url — zero code changes.
Pay-as-you-go
CNY Billing
Pay only for what you use. Supports Alipay & WeChat Pay. Invoicing available for enterprises.
Dedicated
Tech Advisor
Not a ticket system, not a bot. Add our WeChat and talk directly to someone who can solve your problem.
Change base_url, code staysunchanged
Fully compatible with Anthropic and OpenAI formats. No refactoring needed — just point your API endpoint to us.

What OurUsers Say
Real insights and reviews from our users
Before, direct Claude API calls were plagued by latency and timeouts, especially with long text. Since switching to your service, response speeds improved dramatically and I've had zero connection failures.
After switching, even traffic spikes went through smoothly. What really impressed me: at 3am we had a config error and your engineers responded and helped fix it in under 5 minutes. Outstanding service!
