Authenticate with `Authorization: Bearer <GOLDRUSH_API_KEY>`. See [authentication](/goldrush-json-rpc/authentication).

## Parameters

true
```

## Examples

<CodeGroup>
  ```bash wscat theme={null}
  # Connect (header auth works from Node/CLI clients):
  wscat -c "wss://rpc.goldrushdata.com/v1/solana-mainnet" \
    -H "Authorization: Bearer $GOLDRUSH_API_KEY"

  # Once connected, send:
  {"jsonrpc":"2.0","id":1,"method":"signatureUnsubscribe","params":[24006]}
  ```

  ```typescript @solana/kit theme={null}
  import { createSolanaRpcSubscriptions } from "@solana/kit";

  // With @solana/kit you don't call signatureUnsubscribe directly. Abort the
  // subscription's AbortController and the client sends the unsubscribe
  // frame for you:
  const abortController = new AbortController();
  // ... later:
  abortController.abort();
  ```
</CodeGroup>

## Errors
