What OurUsers Say
Real insights and reviews from our users
"When I was calling the Claude API directly, I kept running into latency issues and random timeouts — especially on long context requests, it would just drop mid-stream. Since switching to your API, response times are noticeably faster and I haven't had a single connection failure."
"After switching to your API, even traffic spikes are handled smoothly — their auto-scaling is rock solid. What really impressed me was when we had a config error at 3am, their engineering team responded and helped fix it within 5 minutes. That level of support is rare."

"Your API solved all of these headaches for us. Unified billing, rock-solid connectivity, and 24/7 developer support — we finally get to focus on building our product instead of babysitting API infrastructure."
"We ship fast and constantly need to benchmark different Claude models — Haiku vs Sonnet vs Opus — across various use cases. Your APIA makes it dead simple to switch between models on the fly, and the detailed token usage analytics help us keep costs under tight control."

"Long context support is flawless — we've never had a single truncation issue, even with 200K token inputs. Batch processing is incredibly fast too. This has seriously accelerated our research pipeline. Reliable infrastructure for serious academic work."
"Your API has edge nodes across the globe — our users in Southeast Asia, the Middle East, and Europe all get snappy response times. Plus, they support multiple currencies and payment methods, which saved us the hassle of dealing with cross-border billing. Super convenient for distributed teams."

We're an independent API service provider. We access Anthropic's API through official channels and provide a reliable proxy layer with global routing for developers worldwide. We are not an official Anthropic partner or reseller — but everything we deliver runs on Anthropic's official API endpoints, nothing more, nothing less.
Yes. We take data security seriously. All API traffic is transmitted over encrypted channels. We do not store, log, or review your conversation content. Your requests are forwarded to Anthropic through our infrastructure, and we do not retain the content itself.
We run a multi-node infrastructure with load balancing and automatic failover, targeting 99.9% uptime. A real-time status page is available so you can check service health at any time.
We support major payment methods such as credit cards. Balance is credited instantly after payment. Official electronic invoices are available — you can request one directly from the dashboard after topping up.
This step is for identity verification and to enable one-on-one technical support. It's also how we prevent abuse and maintain service quality. Once verified, you manage your API keys entirely through the dashboard — no further Whatsapp interaction required.
