:::code-group
```ts [index.ts]
import { getNameHistory } from "@ensforge/core";
import { config } from "./config";

const result = await getNameHistory(config, {
  name: "example.eth",
  fromBlock: 22_000_000n,
});
```

```ts [config.ts]
// [!include ~/snippets/core/config.ts]
```
:::

## Parameters

```ts
import type { GetNameHistoryParameters } from "@ensforge/core";
```

### name

`string`

ENS name to operate on. ensforge normalizes it before hashing or contract interaction.

### fromBlock

`bigint`

First block included in the event query.

### toBlock

`bigint | undefined`

Last block included in the event query.

## Return Type

```ts
type GetNameHistoryResult = Awaited<ReturnType<typeof getNameHistory>>;
```

## Effect

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

```ts
import { Effect } from "effect";

const program = getNameHistory.effect(config, parameters);

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

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

## Error

```ts
import type { GetNameHistoryError } from "@ensforge/core";
```

The Promise API rejects with the same typed failures exposed by the Effect error channel. Errors
have a stable `_tag`, `code`, and `message`; boundary errors retain their original `cause`.

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