# List a policy's routing rules

> Returns the rules attached to one routing policy, plus any conflicts between them.



## OpenAPI

````yaml api-reference/llm-gateway-openapi.yml get /admin/routing-rules
openapi: 3.1.0
info:
  title: Barndoor LLM Gateway Admin API
  version: 1.0.0
  description: >
    Configure the Barndoor LLM Gateway programmatically: credentials and
    providers,

    model routes and route groups, pricing, routing policies and rules, launch
    profiles,

    budgets, rate limits, model access, API keys, and organization-wide
    governance settings.


    These are the same APIs the Barndoor app uses under **LLM Management**, and
    the

    Barndoor Terraform provider manages its LLM Gateway resources through them.
    Every

    endpoint is scoped to the organization of the calling token.


    ## Base URL


    ```

    https://app.barndoor.ai/api/llm-gateway

    ```


    For a dedicated deployment, replace `app.barndoor.ai` with the host you sign
    in to.


    ## Authentication


    Send an access token from Barndoor's identity provider in the
    `Authorization` header:


    ```

    Authorization: Bearer <access-token>

    ```


    For scripts and CI, use a service-account token from the OAuth 2.0
    client-credentials

    grant, as the Terraform provider does. The caller needs the admin role in
    the

    organization.


    The `bd-...` API keys you create with these endpoints are for LLM traffic

    (`/v1/chat/completions`, `/v1/messages`, and so on), not for these
    administrative calls.


    ## Partial updates


    Most `PUT` endpoints change only the fields you send. Where a field can be
    cleared,

    send it as `null`; omitting it leaves it unchanged. The exceptions are
    called out on

    the endpoint: `PUT /admin/governance-config` replaces the whole
    configuration,

    `PUT /admin/routing-rules/{id}` replaces the whole rule, and

    `PUT /admin/agent-runtime-profiles/{slug}` replaces the profile's models.


    ## Errors


    Errors are returned as JSON:


    ```json

    { "error": { "message": "retry_on_429_count must be between 0 and 10",
    "type": "invalid_request_error" } }
