AI Model API Relay Station "LLMAPI.JP" Officially Released

The AI model API token relay station "LLMAPI.JP" has officially launched its service today as a gateway service for businesses that makes major global AI models available through a single API.

This service resolves challenges faced by companies when introducing and operating multiple AI models, such as "increased management complexity," "difficulty in cost management," and "connection instability," and supports the construction of a smoother and more secure AI infrastructure.

"Three Complexities" Arising from Multi-Model Operation

As the utilization of generative AI rapidly expands, "multi-model operation," which combines multiple AI models according to their intended use such as text generation, image generation, and video generation, is becoming the standard. However, many companies face common hurdles in its introduction.

The first issue is the increased complexity of management. Account registration and individual API handling are required for each provider such as OpenAI, Anthropic, and Google, resulting in management costs for each of the five companies used.

In addition to this, the complexity of cost management is also a major barrier. Different billing systems and settlement currencies from various vendors are mixed, making it difficult to accurately grasp the overall AI usage costs for the entire company.

Furthermore, connection instability, which tends to occur with network delays and communication errors when connecting directly from Japan to overseas servers, is a serious concern for operation in a production environment.

LLMAPI.JP was developed to comprehensively solve these three challenges: "engineering," "cost," and "stability."

Covers Major Global Models with One API

The biggest strength of LLMAPI.JP is that all modalities of text, image, and video can be called with a single API key.

In the text and inference domain, it supports a wide range of models including cutting-edge models such as "GPT-5.5," "Claude Opus 4.8 / Sonnet 4.6," "Gemini 3.5 Flash / 3.1 Pro," "DeepSeek-V4," "Qwen 3.7," "GLM-5.2," "Kimi K2.6," and "MiniMax M3," as well as image generation models like "Nano Banana Pro" and "GPT Image 2," and video generation models like "Veo 3.1," "Seedance 2.0," and "Kling 3.0."

Adopting OpenAI-compatible API specifications allows for seamless migration by simply changing the endpoint and model name in the existing system's code. When new models are released, LLMAPI.JP immediately supports them, eliminating the need for additional development by the company.

Furthermore, it provides Japanese technical support, Japanese Yen (JPY) settlement, invoice issuance compliant with the invoice system, and low-latency access through proprietary global acceleration nodes as standard features.

Zero Platform Fee and Significant Cost Reduction

LLMAPI.JP achieves outstanding cost performance by consolidating token consumption from numerous users and leveraging the "collective bargaining power" of large-scale contracts.

It completely eliminates the platform service fee (approximately 5.5%) that often occurs with general routing services, achieving zero fees. Additionally, all provided LLM, image generation, and video generation models are offered at a uniform 10% discount from each company's official price.

For enterprise-scale customers, special plans offering up to a 30% discount through individual negotiation based on usage volume are also available. This allows for a fundamental review of AI operational costs, which tend to inflate with the combined use of multiple models.

Enterprise-Level Communication Quality and Security

For stable service provision, we utilize our proprietary global network to ensure low latency even for access from within Japan. The additional latency through the gateway is kept below 50 milliseconds, and in the event of a failure, a failover function automatically switches to an alternative route, guaranteeing **99.95% uptime (SLA)**.

Regarding data security, we adhere to four strict principles: "do not store" customer prompts or business data, "do not use" data for AI model training, "do not perform" analysis or profiling based on data, and strictly adhere to the policy of "purely forwarding requests."

In addition, we support financial management transparency and efficiency through settlement in Japanese Yen and US Dollars based on corporate contracts, and the issuance of consolidated invoices summarizing usage records for all models.

Differences from OpenRouter and Direct Connection

LLMAPI.JP possesses clear competitive advantages compared to other platforms and direct connections.

Compared to OpenRouter, LLMAPI.JP has a cost advantage with 0% platform fee and a 10% discount on all models. Furthermore, enterprise-level support such as low-latency communication through proprietary global nodes, 99.95% SLA guarantee, Japanese technical support, and corporate contracts/unified invoice issuance are strengths that OpenRouter lacks.

Compared to directly connecting to each provider yourself, LLMAPI.JP significantly reduces management and development effort by allowing access to all models with a single API key. Additionally, discounted rates through collective bargaining power and high availability through automatic failover are values that are difficult to achieve with in-house construction.

In summary, "cheaper than OpenRouter, easier than direct connection, and faster than building it yourself" – this is the core competitive advantage of LLMAPI.JP.

Full Operation from the Same Day, Free Testing Also Available

The introduction process for LLMAPI.JP is extremely simple. From account opening to obtaining a free test quota (shortest 10 minutes), changing the endpoint and model name in existing code, and starting usage and billing management on the dashboard, full operation is possible from the same day at the earliest.

A free test quota is also available, allowing you to test operations in a production-equivalent environment without credit card registration. The LLMAPI.JP team will support you in Japanese with technical connection consultations, model price estimates, and large-volume discount evaluations.
