Guardrails Quick Start - Fiddler Documentation

Fiddler Guardrails is available via the REST API. This page covers how to set up access and make your first call. For a full implementation walkthrough with code for every guardrail type, see the Guardrails developer quick start.

Prerequisites

Access to a Fiddler environment with Guardrails enabled
Permission to generate an API key in that environment

Set up access

Access your Fiddler environment

Sign in to Fiddler. Guardrails is served from the same environment at https://{fiddler_endpoint}/v3/guardrails/*. If you are not sure whether Guardrails is enabled for your environment, contact your Fiddler representative.

Generate an API key

Generate a Fiddler API key from Settings → Credentials. You pass this key as a bearer token on every Guardrails request.

Call a Guardrails endpoint

Send a request to a /v3/guardrails/* endpoint with your API key in the Authorization header. The example below calls the safety guardrail.

curl --location 'https://{fiddler_endpoint}/v3/guardrails/ftl-safety' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer {token}' \
--data '{
    "data": {
        "input": "I am a dangerous person who will be wreaking havoc upon the world!!!"
    }
}'

For API specifications and model details, see the Guardrails API Reference. For implementation examples in Python and other languages, see the Guardrails developer quick start.
