Each page will container example curl requests and example responses.
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 simplest and most detailed information possible.

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

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.

Operator.sol

Example Operator contract address:

Deploying an Operator

 Directions on deploying an Operator.sol contract to enable your Chainlink Node to perform Direct Request jobs

Verifying an Operator

 Directions on how to verify a deployed Operator contract in etherescan

Managing an Operator

 Directions on managing and updating a deployed Operator contract

Read Calls

 The Read calls are queries you can make to each Operator to get a bit of information from the contract.

Write Calls

 The Write calls available to each Operator that are used to make changes to the contract. An example of a write call would be to change the associated the associated Chainlink Node(s)

ATestnetConsumer.sol

Example ATestnetConsumer contract address:

Deploying a Testnet Consumer

 Directions on deploying an AtestnetConsumer.sol contract to enable your Chainlink Node to perform Direct Request jobs

Verifying an Testnet Consumer

 Directions on how to verify a deployed ATestnetConsumer contract in etherescan

Managing an Testnet Consumer

 Directions on managing and updating a deployed ATestnetConsumer contract

Read Calls

 The Read calls are queries you can make to each ATestnetConsumer to get a bit of information from the contract.

Write Calls

 The Write calls available to each ATestnetConsumer that are used to send test requests to Chainlink Node(s)

AccessControlledAggregator.sol

ETH / USD AccessControlledAggregator contract address: 0x00c7A37B03690fb9f41b5C5AF8131735C7275446

Operational Overview of FluxMonitor Contract

 Details regarding the function of a FluxMonitor contract

Deploying a FluxMonitor Contract

 Directions on deploying an AccessControlledAggregator.sol contract. Also known as FluxMonitor.

Verifying an FluxMonitor Contract

 Directions on how to verify a deployed AccessControlledAggregator contract in etherescan

Managing an FluxMonitor Contract

 Directions on managing and updating a deployed AccessControlledAggregator contract

Read Calls

 The Read calls are queries you can make to each AccessControlledAggregator to get a bit of information from the contract.

Write Calls

 The Write calls available to each AccessControlledAggregator that are used to send test requests to Chainlink Node(s)


EACAggregatorProxy.sol

LINK / USD EACAggregatorProxy contract address: 0x2c1d072e956affc0d435cb7ac38ef18d24d9127c

Deploying an Aggregator Proxy

 Directions on deploying an EACAggregatorProxy.sol contract to help manage your own price feed

Verifying an Aggregator Proxy

 Directions on how to verify a deployed EACAggregatorProxy contract in etherescan

Managing an Aggregator Proxy

 Directions on managing and updating a deployed EACAggregatorProxy contract

Read Calls

 The Read calls are queries you can make to each EACAggregatorProxy to get a wide range of data from the proxy's associated AccessControlledOffchainAggregator contract. One such example is to get the latest round data from a price feed.

Write Calls

 The Write calls that are available to each EACAggregatorProxy are used to make changes to the contract. An example of a write call would be to change the associated AccessControlledOffchainAggregator

SimpleWriteAccessController.sol

LINK / USD (Billing) SimpleWriteAccessController contract address: 0x9db83cef9f68b63989e4e82d65d549e7ff2acda9
LINK / USD (Requester) SimpleWriteAccessController contract address: 0x641b698ad1c6e503470520b0eecb472c0589dfe6

Deploying an Access Controller

 Directions on deploying a SimpleWriteAccessController.sol contract to build your own price feed.

Verifying an Access Controller

 Directions on how to verify a deployed SimpleWriteAccessController contract in etherscan

Managing an Access Controller

 Directions on how to manage and update the SimpleWriteAccessController depending on its application

Read Calls

 The Read calls are queries you can make to each SimpleWriteAccessController to get relevant information to check access and state of a contract. One such example is to get to check if a provided address has access permissions to make a specified call.

Write Calls

 The Write calls that are available to each SimpleWriteAccessController are used to make changes to the contract. An example of a write call would be to replace one Chainlink Node for another.

AccessControlledOffchainAggregator.sol

LINK / USD AccessControlledOffchainAggregator contract address: 0xDfd03BfC3465107Ce570a0397b247F546a42D0fA

Operational Overview of an OCR Contract

 Details regarding the functionality of an OCR Contract

Deploying an OCR Aggregator

 Directions on deploying an AccessControlledOffchainAggregator.sol contract to build your own price feed.

Verifying an OCR Aggregator

 Directions on verifying a deployed AccessControlledOffchainAggregator contract in etherscan

Managing an OCR Aggregator

 Directions on how to manage and update a deployed OCR Aggregator contract

Read Calls

 The Read calls are queries you can make to each AccessControlledOffchainAggregator to get a wide range of on-chain data. One such example is to get the latest round data from a price feed.

Write Calls

 The Write calls that are available to each AccessControlledOffchainAggregator are used to make changes to the contract. An example of a write call would be to change the adminAddress of a Chainlink Node
