About

FastRouter is a unified API gateway that enables AI applications to access many large language, image, and audio models (like GPT-5, Claude 4 Opus, Gemini 2.5 Pro, Grok 4, etc.) through a single OpenAI-compatible endpoint. It features automatic routing, which dynamically picks the optimal model per request based on factors like cost, latency, and output quality. It supports massive scale (no imposed QPS limits) and ensures high availability via instant failover across model providers. FastRouter also includes cost control and governance tools to set budgets, rate limits, and model permissions per API key or project, and it delivers real-time analytics on token usage, request counts, and spending trends. The integration process is minimal; you simply swap your OpenAI base URL to FastRouter’s endpoint and configure preferences in the dashboard; the routing, optimization, and failover functions then run transparently.

About

RelaySwitch is a hosted AI model API gateway for developers who want to call models from multiple providers through a shared endpoint and account. It exposes an OpenAI-compatible API and supports the Anthropic Messages format for Claude models, allowing compatible SDKs and developer tools to connect by changing the base URL and API key. Its catalog covers chat, image, video, speech and 3D models, with model identifiers and token rates. Usage is billed from a prepaid USD balance; input and output rates are listed separately, and cached input may cost less where supported. Customers can add funds through supported card and digital-asset payment methods, without a monthly subscription. RelaySwitch is intended for developers and teams building applications and agents with hosted AI models, and provides API documentation, model listings and setup guides for supported SDKs and tools.
