Use this when you need: **Build generated app with automatic error fixing**.

import { NeynarAPIClient, Configuration } from "@neynar/nodejs-sdk";

const client = new NeynarAPIClient(
  new Configuration({ apiKey: "YOUR_NEYNAR_API_KEY" })
);

const res = await client.build({
  buildRequest: "value", // required
});
console.log(res);
```

## Parameters

| Parameter      | Type           | Required | Description |
| -------------- | -------------- | :------: | ----------- |
| `buildRequest` | `BuildRequest` |     ✅    | -           |

## Response

Returns a `RequestArgs` object.

## Error Handling

```ts theme={"system"}
try {
  const res = await client.build({

  // Axios/HTTP errors, invalid params, auth issues, etc.
  console.error(err);
}

## Tips

* Provide a **viewerFid** when supported to respect mutes/blocks and include `viewer_context`.
* Keep requests scoped (e.g., use `limit`) to improve latency.
* Cache results where sensible.
