=== '''How to Query Chainlink Contracts''' ===
This page will provide you with information regarding how to query a Chainlink Aggregator

Included are some examples using bash.

''All examples are based on the LINK / USD price feed on Ethereum Mainnet''

----

=== '''Overview''' ===
Each Chainlink Aggregator has a wide range of data that you can query.

From historic price data to the timestamp of the most recent completed round, a lot of information is stored on-chain and available for you to query.

This page will be broken out into each major contract type, and then each individual query that can be made, with examples.

----

=== '''How To Format Request Data ''' ===
Formatting the data we want to send in our RPC calls is a bit tricky if you've never done it before.

This page will assist you in learning how to do this as well as provide outside resources to make it a bit easier.

=== [[Formatting RPC Call Data|'''Formatting RPC Call Data''']] ===
----In the Below tables, you can navigate to pages specific to deploying, verifying, and managing/updating each of the contracts.

Additionally, there are also pages specific to the various read and write calls for each contract with bash+curl examples.

''While curl is nowhere near the most common way to interact with smartcontracts, I felt it would provide the necessary information in the most basic manner.''
