Backend API libraries ethereum

  1. Backend API libraries In order for a software application to interact with the Ethereum blockchain (i.e. read blockchain data and/or send transactions to the network), it must connect to an Ethereum node
  2. The API is a REST interface, accessed via HTTP, designed for use as a public communications protocol. Currently, the only supported return data type is JSON. The beacon node (BN) maintains the state of the beacon chain by communicating with other beacon nodes in the Ethereum 2.0 network
  3. g language of their choice to initialize JSON-RPC requests (under the hood) that interact with Ethereum

How to call API. Description of parameters, example, limits. To call any service API, send a GET request to https://etherapi.net/api/v2 with the required parameters key and method. You can specify the method directly in the address, for example: https://etherapi.net/api/v2/.balance?key=.. or https://etherapi.net/api/v2?method=balance&key=. Our API always returns values in wei, the lowest non-divisible unit in Ethereum. As a friendly reminder, there are 10^18 wei in a single ether (1,000,000,000,000,000,000w = 1ETH). Some say it's wei too much subdivision, but we disagree. Rate Limits and Token API; Help; Pools. Ethereum; Ethereum Classic; ZCash; Monero; Raven; Conflux; Ergo; Overvie Currently cpp-ethereum, go-ethereum, and parity provide JSON-RPC communication over http and IPC (unix socket Linux and OSX/named pipes on Windows). Version 1.4 of go-ethereum, version 1.6 of Parity and version 1.3 of Hyperledger Besu onwards have websocket support
