Introduction

byog (short for “bring-your-own-gas”) is an independent group within the API3 ecosystem that builds high-impact oracle services. We currently operate 133 crypto and forex asset price data feeds each on 25 chains, adding up to a total 3362 unique data feeds.

byog piggybacks on API3's Beacon framework for data feeds and Airnode first-party oracle node as secure and reliable building blocks, and uses its own API that aggregates multiple, well-tested data sources to power data feeds at scale. These data feeds will soon go online on the respective mainnets and other EVM-compatible chains as well!

Why do I bring gas?

Changing the state of a blockchain requires gas. Since each data feed update writes data to the chain, it spends a little amount of gas at each update. That's why you bring your own gas and you only need to bring it when you use it.

Where do I bring gas?

Each data feed requires a source of currency to pay the gas fee of the update. To keep a data feed updated, its sponsor wallet must be funded. You can bring your own gas to the sponsor wallet by funding it.

How do I use byog data feeds?

It takes no time to use byog data feeds in your own project. For more see our guide.
