  title: Sommelier Finance Integrations API
  description: 'Public, read-only REST API for the Sommelier (Somm) DeFi vault protocol. Exposes on-chain vault ("cellar") performance data — daily and hourly snapshots (APY, TVL, share price, total assets), protocol-wide total value locked, per-cellar snapshots, and integration-specific datasets (Kelp, ether.fi points and balances). All endpoints are unauthenticated HTTP GETs with path-based parameters and a common `{ "Response": ... }` envelope. Currently supports the `ethereum` network.'
