With chainlink you have access to price oracles via blockchain. The requests are read calls to a smart contract. The public ethers provider might be too slow for a higher number of pairs or at times of high demand. Therefore, it might be needed to have access to an Infura account (100000 Requests/Day for free). There you can get an endpoint for your market maker (like https://mainnet.infura.io/v3/...), You can add this with the `infuraUrl` field in `config.json`, like this:
