The HTTP Provider allows sending requests using HTTP. it does not support subscriptions so you won´t be able to listen to events such as new blocks or balance changes. It is usually preferrable using the [WsProvider](_ws_index_.wsprovider.md).
*__example__*: import createApi from '@polkadot/api'; import WsProvider from '@polkadot/api-provider/ws';

const provider = new WsProvider('[http://127.0.0.1:9933')](http://127.0.0.1:9933')); const api = createApi(provider);

*__see__*: [WsProvider](_ws_index_.wsprovider.md)
