Example Usage

from openrouter import OpenRouter
import os


with OpenRouter(
    http_referer="<value>",
    x_open_router_title="<value>",
    x_open_router_categories="<value>",
    api_key=os.getenv("OPENROUTER_API_KEY", ""),
) as open_router:

    res = open_router.guardrails.list(offset=0, limit=50)

    while res is not None:
        # Handle items

        res = res.next()

Parameters

Parameter	Type	Required	Description	Example
`http_referer`	Optional[str]	:heavy_minus_sign:	The app identifier should be your app’s URL and is used as the primary identifier for rankings. This is used to track API usage per application.
`x_open_router_title`	Optional[str]	:heavy_minus_sign:	The app display name allows you to customize how your app appears in OpenRouter’s dashboard.
`x_open_router_categories`	Optional[str]	:heavy_minus_sign:	Comma-separated list of app categories (e.g. “cli-agent,cloud-agent”). Used for marketplace rankings.
`offset`	OptionalNullable[int]	:heavy_minus_sign:	Number of records to skip for pagination	0
`limit`	Optional[int]	:heavy_minus_sign:	Maximum number of records to return (max 100)	50
`workspace_id`	Optional[str]	:heavy_minus_sign:	Filter guardrails by workspace ID. By default, guardrails in the default workspace are returned.	0df9e665-d932-5740-b2c7-b52af166bc11
`retries`	Optional[utils.RetryConfig]	:heavy_minus_sign:	Configuration to override the default retry behavior of the client.

Response

operations.ListGuardrailsResponse

Errors

Error Type	Status Code	Content Type
errors.BadRequestResponseError	400	application/json
errors.UnauthorizedResponseError	401	application/json
errors.InternalServerResponseError	500	application/json
errors.OpenRouterDefaultError	4XX, 5XX	/

create

Create a new guardrail for the authenticated user. A newly created guardrail enforces nothing until it is assigned to API keys or organization members; workspace_id places the guardrail in a workspace but does not apply it to that workspace’s traffic. To restrict all traffic in a workspace, update the workspace’s default guardrail instead. Set allowed_data_regions to enforce In-Region Routing: governed requests must arrive through one of the listed OpenRouter domains and are rejected with a 403 otherwise. Management key required.

Example Usage

from openrouter import OpenRouter
import os


with OpenRouter(
    http_referer="<value>",
    x_open_router_title="<value>",
    x_open_router_categories="<value>",

    ], allowed_models=None, allowed_providers=[
        "openai",
        "anthropic",
        "deepseek",
    ], description="A guardrail for limiting API usage", enforce_zdr_anthropic=True, enforce_zdr_google=False, enforce_zdr_openai=True, enforce_zdr_other=False, enforce_zdr_xai=False, ignored_models=None, ignored_providers=None, limit_usd=50, reset_interval="monthly")

Use enforce_zdr_anthropic, enforce_zdr_openai, enforce_zdr_google, enforce_zdr_xai, and enforce_zdr_other instead. When provided, its value is copied into any of those per-provider fields that are not explicitly specified on the request.	false

`include_byok_in_budgets`	Optional[bool]	:heavy_minus_sign:	Whether BYOK (bring-your-own-key) inference spend counts toward this guardrail’s limit_usd, in addition to OpenRouter credit spend. Defaults to false.	false
`limit_usd`	OptionalNullable[float]	:heavy_minus_sign:	Spending limit in USD. Must be provided together with `reset_interval`: a request that sets only one of the two is rejected with a 400.	50
`reset_interval`	OptionalNullable[components.GuardrailInterval]	:heavy_minus_sign:	Interval at which the limit resets (daily, weekly, monthly)	monthly
`workspace_id`	Optional[str]	:heavy_minus_sign:	The workspace to create the guardrail in. When omitted, the guardrail is created in the default workspace; if that default has been deleted, the request returns a 400 and you must pass `workspace_id` explicitly. This only places the guardrail in the workspace; the created guardrail enforces nothing for that workspace’s traffic until it is assigned to API keys or members. To restrict all traffic in a workspace, update the workspace’s default guardrail instead.	0df9e665-d932-5740-b2c7-b52af166bc11
