title: Introspection Identity Details Schema Endpoint
---

The identity details schema introspection endpoint returns JSON Schema for the identity details contract exposed by your configured identity details provider.

## Endpoint

`GET /.cratis/identity-details/schema`

## When Arc maps this endpoint

Normal Arc identity activation maps this endpoint unless one with the same endpoint name already exists. It is explicitly anonymous in every environment, including Production; see [production access](/arc/backend/csharp/introspection/#production-access).

## What it returns

The endpoint returns a JSON Schema document generated from the runtime identity details type:

- If your provider implements `IProvideIdentityDetails<TDetails>`, Arc generates schema for `TDetails`.
- If your provider only implements non-generic `IProvideIdentityDetails`, Arc generates schema for `object`.
- If no identity details provider is configured, Arc returns an empty schema object (`{}`).

## Typical uses

- Discover the identity details shape at runtime without hardcoding provider types.
- Drive client-side tooling that validates or renders identity details data.
- Keep integration tests and diagnostics aligned with the active identity provider contract.
