Data Feed Reader Example

Intro​

nodary-examples aims to guide users on how to read data from data feeds or dAPIs (decentralized APIs). Data feeds are sourced by a single beacon and dAPIs can be sourced by either one beacon or aggregation of more beacons. Since dAPIs can be sourced by aggregation of beacons, it is more reliable to use dAPIs. You can see full list of Nodary data feeds here and dAPIs in API3 Market. Follow through nodary-examples's README.md and see the example contract.

Proxies​

Data feeds and dAPIs are read via proxies. Each data feed or dAPI ideally should have one proxy. One can use nodary-examples's Advanced section for deploying proxy. It is ideal to use API3 Market for dAPIs, it is just a few clicks. See DataFeedProxy.sol and DapiProxy.sol contracts.
