### Related API: [Lookup cast by hash or URL](https://docs.neynar.com/reference/lookup-cast-by-hash-or-url)

Cast url doesn’t contain all the full cast hash value, it usually looks like this: `https://farcaster.xyz/dwr.eth/0x029f7cce`.This guide demonstrates how to fetch cast information from cast url.Check out this [Getting started guide](https://docs.neynar.com/docs/getting-started-with-neynar) to learn how to set up your environment and get an API key.First, initialize the client:

Javascript

```javascript
// npm i @neynar/nodejs-sdk
import { NeynarAPIClient, Configuration } from "@neynar/nodejs-sdk";

// make sure to set your NEYNAR_API_KEY .env
// don't have an API key yet? get one at neynar.com
const config = new Configuration({
  apiKey: process.env.NEYNAR_API_KEY,
});

const client = new NeynarAPIClient(config);
```

Then fetch the cast:

Javascript

```javascript
// @dwr.eth AMA with @balajis.eth on Farcaster
const url = "https://farcaster.xyz/dwr.eth/0x029f7cce";
const cast = await client.lookupCastByHashOrUrl({
  identifier: url,
  type: CastParamType.Url,
});
console.log(cast);
```

Example output:

```

  cast: {
    object: "cast_hydrated",
    hash: "0x029f7cceef2f0078f34949d6e339070fc6eb47b4",

Obviously, you can also fetch cast by hash:

Javascript

```javascript
// full hash of the warpcast.com/dwr.eth/0x029f7cce
const hash = "0x029f7cceef2f0078f34949d6e339070fc6eb47b4";
const cast = (await client.lookUpCastByHashOrUrl({
  identifier: hash,
  type: CastParamType.Hash,
}));
console.log(cast);
```

Which will return the same result as above.
