Contracts through which API3 services are delivered
This package provides the tools to integrate data feeds that can be found at the API3 Market. The typical workflow is as follows:
- Purchase data feed subscriptions and get the respective proxy addresses at the API3 Market
- Use the proxy address computation utility function provided by this package (
computeApi3ReaderProxyV1Address()
) to validate the proxy addresses being used - Use the proxy contract interfaces provided by this package in the reader contract, as demonstrated in https://github.com/api3dao/data-feed-reader-example
A more complete list of what this package includes is as follows:
- All contracts that facilitate API3 data feed services, including OEV auctions
@typechain/ethers-v6
typings of these contracts- Addresses of the API3 deployments of these contracts
- Proxy address computation utility functions
