 No matter what you wish to build on Filecoin, you'll generally need a few basic elements:
 
-- **A node.** Each Filecoin-based service or application will need to use at least one Filecoin node that maintains consensus. All interactions with the network must flow through an up-to-date node: sending and receiving market deals, sending and receiving data, and more. You can host this yourself, or choose a [hosted node](/build/start-building/interacting-with-the-network/) option.
-- **An API.** Depending on language, and your preference for more granular or high-level commands, you can either directly use the node's go RPC API, or use one of the available [JS API client libraries](/build/developer-tools/wallets-signing-tools-api-clients/#api-clients).
