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."

FAQ
You might alsowant to know
We're an independent third-party service provider with access through two official channels: Anthropic's native API and AWS Bedrock. We're not an official Anthropic reseller, but 100% of requests are forwarded directly to official endpoints.
Neither. We use only official API keys and Bedrock's official integration, preserving the full native capabilities of Opus / Sonnet / Haiku — including 1M context and Tool Use. Feel free to benchmark against the official API.
No. All requests are encrypted over HTTPS. We don't persist conversation content on our servers — only token counts and status codes are recorded for billing. Enterprise customers can sign a DPA.
Yes. Both personal and corporate billing names are accepted. We issue standard electronic invoices and VAT invoices — request one from the dashboard in a single click. Enterprise customers can also pay by bank transfer with a formal contract.
Register via the top-right button → create a Key in the dashboard → copy the base_url. You can be up and running in 5 minutes. Everything is self-service; for enterprise contracts or large volumes, contact our sales team.
We're a formally registered technology company with a track record of stable operation. All user funds are held through third-party payment platforms. Our operations are compliant and transparent, and we're committed to serving developers long-term.
