# Euler Finance GraphQL API

Euler Finance V2 exposes on-chain vault and account data through GraphQL subgraphs hosted on Goldsky. The subgraphs index factory-created EulerVault and EulerEarn contracts, tracking active accounts (deposits and borrows) and per-account vault balances across all supported EVM-compatible networks.

The API requires no authentication. Queries are submitted as HTTP POST requests with a JSON body containing the `query` field. The Mainnet deployment is the canonical reference; equivalent subgraphs are available for Arbitrum, Base, Sonic, Berachain, Optimism, Avalanche, BSC, and other supported networks by substituting the network name in the path.
