ether.fi
ether.fi is a non-custodial, decentralized Ethereum liquid restaking protocol where stakers retain control of their validator keys. Users deposit ETH to mint eETH, a rebasing liquid restaking token (LRT), or wrap it into weETH, the non-rebasing ERC-20 used across DeFi and bridged cross-chain via LayerZero to networks including Arbitrum, Optimism, Base, Linea, Mode, Scroll, BNB Chain, Blast, Mantle, and Solana. Beyond ETH liquid restaking, ether.fi has expanded into eBTC (Bitcoin restaking) and eUSD (stablecoin restaking), Liquid auto- balancing strategy vaults, the ether.fi Cash non-custodial credit card with cashback, "The Club" membership tier program, and an AVS operator stack that runs services on EigenLayer, Symbiotic, and Karak. The protocol is governed by the ETHFI token via governance.ether.fi. ether.fi has no public REST API or developer SDK — its public surface is on-chain: open-source Solidity smart contracts on Ethereum mainnet (eETH, weETH, LiquidityPool, EtherFiNodesManager, EtherFiOracle, MembershipManager, ETHFI), cross-chain bridge contracts (weETH-cross-chain via LayerZero, ETHFI via Wormhole NTT), AVS operator contracts, plus operator tooling (etherfi-avs-operator, eigenpod-proofs-generation) and a public subgraph indexing protocol events. ether.fi is one of the largest LRT protocols by TVL with deep integrations across Aave, Pendle, Gearbox, Morpho, and other DeFi venues.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles ether.fi the way a machine reads it — 21 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — ether.fi scores 10.5/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
