# Using Band Oracle

The repo <https://github.com/harmony-one/band_oracle> contains examples on how to fetch price feeds using band oracle.

There are two scenarios:

* Fetching price feed in your javascript application code
* Fetching price feed in your smart contract

### Requesting data using BandChain.js library

<https://github.com/harmony-one/band_oracle/blob/main/main.js>

```
git clone https://github.com/harmony-one/band_oracle
cd band_oracle

yarn
node main.js
```

### Using BandChain data in EVM Smart Contract in Harmony

<https://github.com/harmony-one/band_oracle>

```
git clone https://github.com/harmony-one/band_oracle
cd band_oracle

yarn
export PRIVATE_KEY=place your private key here
yarn hardhat run ./scripts/deploy.js
```

Contract's been deployed and you can call `getPrice` or `getMultiPrices` to get actual prices. More details with code snippets are in <https://docs.harmony.one/home/developers/tools/oracle-band-protocol>
