# Gargantua

> Endpoints and example requests for Gargantua, the Hyperbridge test network.

Hyperbridge (short for hyper-scalable bridge) is innovated as a cross-chain solution built as an interoperability coprocessor. Hyperbridge is crafted to scale cryptographically secure, consensus, and state-proof-based interoperability across all blockchains.

### How to Connect to Gargantua

#### Using Private Endpoint

Using API keys on an RPC node provides better tracking and monitoring of API usage.

Secure your data, speed up your queries, and take control of your API usage with our RPC API endpoint and personalized API keys. [Sign up now](https://app.blockops.network) to get your own API key.

To get your API key, create a project using a unique Identifier as the project name and select Gargantua from the network options.

#### Send requests

<Note>
  All requests are `POST` requests.
</Note>

**Connect via Command Line**

You can connect to the network using websocket or HTTP with your API key in two ways:

* Adding the API key as a query string `?api_key=${APIKEY}`
* Or the request header `-H 'authorization: APIKEY ${APIKEY}'`

**Curl**

For example, the following CURL command can be used to get header and body of a relay chain block.

```bash theme={null}
curl -H "Content-Type: application/json" -H 'authorization: APIKEY xxxx'  -d '{"id":1, "jsonrpc":"2.0", "method": "chain_getBlock"}' https://gargantua-rpc.blockops.network/rpc
```

Here is the response you will receive back.

```bash theme={null}
{"jsonrpc":"2.0","result":{"block":{"header":{"parentHash":"0x381dd358f0b1e328e861822b2a51a72e8dc064803a5c7ccc96277da3b16d7667","number":"0xe07a1d","stateRoot":"0xa2aacd7ef5d7ff66da1df6643b3e1c13975d210363c568f1bed51bad56cf40db","extrinsicsRoot":"0x00bc7f1504c9a07364835d80d2114ca3d4e7ad774453198b119bea9be2a1f7c1","digest":{"logs":["0x0642414245b50103d8000000d17aae1000000000768dc1931ba697bb9ab4a08debf5d710bd1f55e6325d65315161c2340cc0217170dfe2df24a3680c8ff48868ac665f4b34ebefa4bc844d510c848d9fc99252035db579a0acbf52cded336d6daf6ab7fdb1d1eee0d480e6388c2a12785d4de809"]},"justifications":null},"id":1}
```

**Wscat**

If you want to send data requests with WebSockets, you can use several libraries or wscat. You can install and use wscat as follows:

* Download wscat from [https://www.npmjs.com/package/wscat](https://www.npmjs.com/package/wscat)
* Install wscat by running the following command: `npm install -g wscat`

You can connect to the network with wscat using two options by adding the API key as a query string.

```bash theme={null}
wscat -c 'wss://gargantua-rpc.blockops.network/ws?api_key=*********************'
```

Or the request header.

```bash theme={null}
wscat -c 'wss://gargantua-rpc.blockops.network/ws' --header 'authorization: APIKEY xxxx'
```

After executing the command, the terminal will display a message indicating that the connection has been enabled successfully.

```bash theme={null}
Connected (press CTRL+C to quit)
>
```

Then, you can send the following request:

```
{"id":1, "jsonrpc":"2.0", "method": "chain_getBlock"}
```
