OmniRoute is an open-source gateway you run yourself: one endpoint in front of 350 providers, with quota-aware fallback, token compression, and MCP support, built for Claude Code, Codex, Cursor, OpenCode, Cline and Copilot. Opper is listed in its provider catalogue, so you paste your Opper key once under Providers and every agent you point at OmniRoute can pick from Opper's 700+ models, EU-hosted routes included, alongside whatever else you have configured.
OmniRouteoninIn OmniRoute (v3.8.51 or later), open Providers → API key providers, pick Opper and paste your key; on older builds add a custom OpenAI-compatible provider with base URL https://api.opper.ai/v3/compat. Then pick NVIDIA-Nemotron-3-Ultra-550B-A55B.
NVIDIA-Nemotron-3-Ultra-550B-A55B runs on the routes below. Route only to EU providers when your data has to stay in Europe.
