## Testing

Once you have your API key, you can query the RPC with a command similar to the following:

```
curl https://mainnet.sandshrew.io/v1/YOUR-API-KEY \
  -H 'Content-Type: application/json' \
  -d '{
    "jsonrpc": "2.0", 
    "id": 1, 
    "method": "esplora_blocks:tip:height",
    "params": []
}'
```

Your API key grants you access to all SANDSHREW namespaces, for all networks supported by SANDSHREW, identified by the subdomain in the URI. In the preceding example, the RPC will serve data for the signet network.

## Network Endpoints
