Arweave is a permanent decentralized data storage network that enables developers to store data forever with a single upfront payment. It provides REST and GraphQL APIs for uploading data, querying blocks and transactions by tags and metadata, retrieving wallet balances, and accessing the permaweb data ecosystem. The network uses the AR token for storage fees and supports bundled uploads via the Turbo service with fiat and multi-chain crypto payment options.
