Data delivery, usage | DIA Documentation

The price feed is created and published via an API endpoint, utilizing the previously selected data sources and computational methodologies. This feed can be accessed off-chain using either RestAPI or DIA GraphQL, which allows for greater adaptability and direct modification of feed attributes.

Off-chain and on-chain delivery methods can be configured with custom update triggers, enhancing the feed's usability and reliability across various applications.

Update triggers

Update triggers are the rules that dictate how oracles refresh to mirror the most recent value of the data feed. These triggers are adaptable and can be tailored to optimally cater to particular scenarios, such as the price feeds of assets with low liquidity.

Each oracle can be customised to push data feed updates live based on the following parameters:
