# Create a judge class

POST

/v1/judge-classes

```sh
curl --request POST \
  --url https://example.com/v1/judge-classes \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{ "scope": { "kind": "tenant" }, "name": "example", "weight": 1, "description": "example", "assertableBy": { "minReviewerRole": "standard", "principalKinds": [ "user" ], "principalIds": [ "example" ] } }'
```

A named kind of judge with a weight, scoped to the tenant, a project, or an agent in a project. Names are unique among the live classes of a scope. Needs `admin` on the tenant (tenant scope) or the project.

## Authorizations

- **[bearerAuth](https://docs.kindgi.com/v0.1.10/reference/api.md#bearerauth)**

## Parameters

### Header Parameters

**Idempotency-Key**

string

\>= 1 characters

Caller-supplied idempotency key, scoped to the caller: the same key from someone else in the tenant is their own request (from 0.1.5). Retries with the same key return the original response byte-identical (per `docs/API-ROUTE-CONVENTIONS.md` §3.1). A retry sent while the first request still runs is answered `409 idempotency-key-in-flight` with `Retry-After`, on a runtime whose store holds keys (from 0.1.5); retry after it, and you get the first request’s answer. An answer that carries a secret (a new API key or public run token, a session token, a generated signing secret) isn’t kept: a retry gets `409 idempotency-key-replay-withheld`, with the first request’s status and when it succeeded (from 0.1.5).
