## Amsterdam

| Service          | URL                             | Protocol                  |
| ---------------- | ------------------------------- | ------------------------- |
| RPC              | `http://ams.rpc.sodae.io:8899`  | JSON-RPC 2.0, HTTP `POST` |
| Yellowstone gRPC | `http://ams.rpc.sodae.io:10201` | gRPC over HTTP/2          |
| Preplay Shreds   | `http://ams.rpc.sodae.io:10301` | gRPC over HTTP/2          |

The gRPC ports speak plaintext HTTP/2. Configure your client for an insecure (non-TLS) channel:

<CodeGroup>
  ```rust Rust theme={null}
  GeyserGrpcClient::build_from_shared("http://ams.rpc.sodae.io:10201")?
  ```

  ```typescript TypeScript theme={null}
  new Client("http://ams.rpc.sodae.io:10201", token, {});
  ```

  ```go Go theme={null}
  grpc.NewClient("ams.rpc.sodae.io:10201",
      grpc.WithTransportCredentials(insecure.NewCredentials()))
  ```
</CodeGroup>

[Price Feeds](/price-feeds) and [SodaStream](/sodastream) deliver to your server rather than through a public endpoint.

## Choosing a location

Place your servers in or near Amsterdam for the lowest latency. The endpoints are the same for every plan; what you can use depends on your plan and bound IPs.

## WebSocket

RPC does not offer WebSocket subscriptions. For real-time data, use [Yellowstone gRPC](/yellowstone/overview), which covers account, transaction and slot updates with server-side filtering.
