Always On Models
One API for Unified Access to Leading AI Models
OneHop provides enterprises with a unified gateway to AI model access. With a single integration, teams can flexibly connect to leading models across providers, reducing duplicated development and maintenance effort while making model adoption, switching, and scaling significantly more efficient.

Always On Access
Multi-Layer Redundancy Architecture for High-Availability AI Services
Stability is not an optional feature. It is a core principle embedded in OneHop's architecture from the ground up. By building a comprehensive, fully redundant system across the network, gateway, and model service layers, OneHop delivers greater resilience, failover capability, and recovery performance under abnormal conditions, minimizing the impact of interruptions on production workloads.

Always On Value
Worry-Free Refunds, Greater Confidence in Use
OneHop offers a worry-free refund policy for greater peace of mind. Users may request a refund at any time for any unused account balance, reducing the burden of locked-in funds while providing greater flexibility and certainty throughout the service experience. With transparent policies and a more user-friendly approach, OneHop helps businesses adopt, test, and scale AI with greater confidence.

Frequently asked questions
What is an AI gateway (AI router)?
An AI gateway is a unified access layer between your application and model providers. OneHop puts hundreds of AI models behind one API and one key, handling routing, billing, and failover on the backend so you don't integrate each provider separately.
How is OneHop different from OpenRouter, and is it an alternative?
OneHop is an alternative to aggregator gateways like OpenRouter, built reliability-first: multi-layer redundancy for high availability, transparent usage-based billing, and a refundable balance.
How do I use OneHop with cc switch, Claude Code, or Cursor?
Point the tool's base_url at OneHop's gateway and use your OneHop key. OpenAI, Anthropic, and Vertex protocols are supported, so existing setups switch over by changing one line.
Which models and protocols are supported?
Hundreds of models across OpenAI, Anthropic, Google, DeepSeek, MiniMax, ByteDance and more, compatible with the OpenAI, Anthropic, and Vertex protocols. New models are added continuously.
How does billing work, and can I get a refund?
Usage-based, prepaid credits with one unified bill and transparent markup, no monthly minimum. Any unused account balance can be refunded at any time.
