What is OmniRail (RAIL)?
OmniRail is a unified API and (MCP) server that gives AI agents access to AI models from many providers through a single API key. The platform routes requests to several hundred models behind OpenAI-compatible endpoints: chat completions, image generation and editing, video generation, text-to-speech, speech-to-text and embeddings.
How does OmniRail work?
Agents can also use the same catalog through the OmniRail MCP server, hosted at omnirail.org/api/mcp or run locally as an npm package Usage is prepaid in crypto on Robinhood Chain: users deposit USDG or ETH and create API keys with optional spend limits, or agents pay per request with the x402 protocol. Every request first reserves its maximum possible cost as a hold, is executed at the provider, and is then billed at the cost the provider reports, with the remainder of the hold released. RAIL is the project's ERC-20 token on Robinhood Chain.
