# HTTP / WebSocket APIs

You can communicate with the XRP Ledger through the `rippled` servers' publicly available APIs.
 | 
			
		||||
You can communicate directly with the XRP Ledger through HTTP-based APIs provided by the core `rippled` server as well as the Clio server. Both types of server provide JSON-RPC and WebSocket APIs with mostly the same functionality. JSON-RPC uses a strict request-response paradigm similar to a REST API, but WebSocket uses a single persistent connection where the server can push messages to the client asynchronously. For more information, see [Get Started Using HTTP / WebSocket APIs](../../tutorials/http-websocket-apis/build-apps/get-started.md).

[{% inline-svg file="/docs/img/api-functionality-venn-diagram.svg" /%}](/docs/img/api-functionality-venn-diagram.svg "Diagram: Most API methods are provided by both rippled and Clio servers. The rippled server provides admin methods, provides pending/unvalidated data including transaction queue, and has a live view of consensus and peer-to-peer network. The Clio server scales efficiently, provides additional methods nft_history, nft_info, nfts_by_issuer, and mpt_holders, and serves rippled-exclusive API requests by forwarding.")
 | 
			
		||||
 | 
			
		||||
## API Versioning
 | 
			
		||||
 | 
			
		||||
Currently, there are two API versions: `1` and `2` {% badge href="https://github.com/XRPLF/rippled/releases/tag/2.0.0" %}New in: rippled 2.0.0{% /badge %}. The server reports the range of supported API versions in the [`version` API method](public-api-methods/server-info-methods/version.md); you can specify which version to use in your API requests.
 | 
			
		||||
 | 
			
		||||
Separate API requests can use different API versions even on the same persistent connection. For example, if you connect through WebSocket to a server that supports API versions 1 and 2, you can make an `account_tx` request using API version 2 and then make another `account_tx` request using API version 1 from the same connection.
 | 
			
		||||
 | 
			
		||||

 | 
			
		||||
### Specifying a Version
 | 
			
		||||
 | 
			
		||||
## Default API Versions
 | 
			
		||||
Use the `api_version` field of the request to specify which API version to use. See [Request Formatting](./api-conventions/request-formatting.md) for example requests.
 | 
			
		||||
 | 
			
		||||
The table below shows which version of the `rippled` API is used if you don't specify it in the request:
 | 
			
		||||
Separate API requests can use different API versions even on the same persistent connection. For example, if you connect through WebSocket to a server that supports API versions 1 and 2, you can make an `account_tx` request using API version 2 and then make another `account_tx` request using API version 1 from the same connection.

If you do not specify an API version when making a request directly to the server, the server uses API v1.

The following table shows which API version each library uses when you don't specify which API version to use:
