## Effect

Use `.effect` when composing the method in an Effect program. The success and error channels remain
fully typed.

```ts
import { Effect } from "effect";
import { sdk } from "./client";

const program = sdk.registration.getRegistrationPrice.effect(parameters);

type Success = Effect.Effect.Success<typeof program>;
type Failure = Effect.Effect.Error<typeof program>;

const result = await Effect.runPromise(program);
```

## Request

Use `.request` to describe the read without executing it, then include it in a typed
[read batch](/core/guides/batching).

```ts
const request = sdk.registration.getRegistrationPrice.request(parameters);
```

## Error

```ts
import type { GetRegistrationPriceError } from "@ensforge/sdk/registration";
```

The method rejects with the corresponding Core action errors. Use `.effect` to keep those failures
in the typed Effect error channel.

See [Error Handling](/sdk/guides/error-handling).
