Run OmniRoute on GLM 5.1
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 agents connected to OmniRoute can choose compatible models from Opper's catalogue, EU-hosted routes included, alongside whatever else you have configured.
