Cache layer
A cache layer is a web service, that caches prices data signed by data providers.
By default, Redstone API fetches data from the Redstone cache layer. It works faster than fetching directly from the Arweave Blockchain. This approach maintains data integrity thanks to built-in signature verification.

Fetching prices from Arweave Blockchain

We strongly recommend using the default fetching mechanism. However, anyone may fetch data directly from the Arweave by initialising a new RedstoneApi client and setting useCache option to false.
const redstoneArweaveClient = new redstone.Api({
useCache: false,
});
const price = await redstoneArweaveClient.getPrice("AR");
console.log(price.value); // AR price value fetched directly from Arweave
