Flare
Flare (FLR) is an EVM-compatible Layer 1 using Snowman++ consensus with proof-of-stake Sybil resistance, while validators also participate as data providers for Flare’s enshrined protocols. Solidity, Vyper, and other EVM languages compile to EVM bytecode, with Ethereum-style accounts, transaction formats, contract storage, and Merkle Patricia Trie state maintained by nodes. Because Flare preserves Ethereum execution semantics while adding protocol-level data services, standard EVM tooling and JSON-RPC remain the baseline for application interaction.
Flare API Methods and Endpoints
NOWNodes exposes Flare's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions.
Browse the interfaces below for endpoint details, request parameters, response formats, and integration examples. Create an API key, select Mainnet or Testnet, choose the required interface, and start sending requests from your application.
