Route with evidence.
Run where your keys already live.

ONE CORE, THREE SURFACES

Start with an API call.
Keep the same decision everywhere.

The hosted endpoint routes metadata only. The CLI can route locally. The MCP server lets compatible agents ask Nymrel Agent for the same explainable decision.

• Every rejected model carries stable reason codes.
• Equal scores break deterministically by model and provider ID.
• Your quality and reliability inputs remain your evidence—not our marketing claims.
