Question 1

What is Ethereum (ETH) API used for?

Accepted Answer

APIs exposed by Ethereum RPC nodes are typically used for retrieving information stored on the blockchain, sending information to the blockchain, and building applications. Some developers also use aggregated APIs, such as CoinStats Ethereum API, which provide wallet balances, ERC-20 token holdings, and DeFi positions across multiple EVM-compatible networks. Its MCP server gives AI assistants and LLM-powered applications access to the same data.

Question 2

What is the role of an Ethereum API in building decentralized applications (dApps)?

Accepted Answer

Decentralized applications rely on data from blockchain networks to fulfill user requests. Decentralized software built for Ethereum can't function independently - it needs a connection to blockchain nodes to respond to user requests, which API provides.

Question 3

How to start using Ethereum API?

Accepted Answer

To get started with the ETH API by GetBlock, users need to sign up for a new account or sign in to their existing one. From there, they can generate RPC URLs and start using them immediately.

Question 4

Are there any rate limits or usage restrictions on the Ethereum (ETH) API?

Accepted Answer

The usage of the Ethereum API is typically limited by the number of requests per second (RPS). With GetBlock's free services, users can send 20 requests per seconf, while paid options range from 100 RPS to 1,000+ RPS, depending on the plan.
