Flux RouterDocumentation

Crush

Add FluxRouter as an OpenAI-compatible provider in crush.json at the /v1 base URL.

Crush talks to FluxRouter through an OpenAI-compatible provider, which uses the /v1 endpoint. Your Flux key is the only credential it needs.

For abilities as well as models, such as reading pages and making images, add the Flux tools server with the same key if your version of the tool supports remote MCP servers.

Manual config

Add a flux block under providers in crush.json:

json
{
  "providers": {
    "flux": {
      "type": "openai-compat",
      "base_url": "https://api.fluxrouter.ai/v1",
      "api_key": "$FLUX_API_KEY"
    }
  }
}

Then export your Flux key:

bash
export FLUX_API_KEY=sk-YOUR-FLUX-KEY

Test it

Run crush and send a prompt. A reply confirms the connection. Check your FluxRouter dashboard to confirm the request landed.

Notes

flux-auto is the default and routes each request for you. If you want to pin a single lane, set the model to flux-fast, flux-standard, or flux-reasoning.

Crush executes any value wrapped in $(...) in crush.json as a shell command. Use a plain $FLUX_API_KEY reference for the key, never $(...).
