# Use Public API Server(RPC)

Not desiring to install and manage the WEMIX3.0 client, it is possible to use the RPC server WEMIX Foundation provides 24 hours a day for free. 

Developers can leverage RPC servers and public network endpoints to interact with on-chain data and send different types of transactions to the network. The API follows the JSON-RPC standard, a stateless and lightweight Remote Procedure Call (RPC) protocol commonly used when interacting with blockchain networks.

**JSON-RPC calls**

[WEMIX3.0 JSON-RPC API](/en/dapp-developer/json-rpc.md) is 100% compatible with standard Web3 [Ethereum JSON-RPC API](https://eth.wiki/json-rpc/API)**.**

**Speed limit**

Rate limiting is a function to limit the rate for incoming connections. For example, if too many references co-occur and burden the server, connections that exceed the defined rate limit may be rejected.

The RPC server has a speed limit for each IP to prevent malicious attacks and provide reliable services to more users.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wemix.com/en/quick-start/start-node/use-public-api-server-rpc.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
