Euler Finance
Euler is a permissionless modular lending protocol that enables users to lend, borrow, and build custom lending markets without limits. The platform provides REST APIs for querying vaults, account positions, interest rates, liquidation thresholds, token prices, APYs, reward campaigns, and lending market analytics across multiple EVM-compatible networks.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Euler Finance the way a machine reads it — 233 machine-readable artifacts across 24 APIs, 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 — Euler Finance scores 49.5/100 (developing), with a separate agent-readiness read of 48/100 (agent ready). 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.

How we profile Euler Finance
Each block below is one kind of artifact we hold for Euler Finance. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 24
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Euler Off-Chain Prices API
An unofficial REST endpoint for fetching USD-denominated asset prices for ERC-20 tokens across supported networks. Accepts chainId and comma-separated asset addresses. Returns p...
Euler Subgraphs (GraphQL)
GraphQL-based subgraph endpoints hosted on Goldsky for querying indexed Euler V2 protocol data including vault states, account positions, borrow/supply history, interest rates, ...
Euler V2 TypeScript SDK
The recommended TypeScript entry point for applications, bots, scripts, and operational tooling built on Euler V2. Provides protocol data fetching, EVC batch composition, transa...
Euler Finance Accounts API
Account activity, discovered positions, and sub-account relationships. Legacy nested account payloads are flattened into account-vault rows in v3.
Euler Finance APYs API
Base and intrinsic APY surfaces. In v3, APY families are split into dedicated endpoints instead of being embedded inconsistently across larger payloads.
Euler Finance Auth API
Authentication and authorization conventions used across the API, including API keys, admin secrets, and rate-limit behavior.
Euler Finance Chains API
Chain inventory and per-chain protocol summaries. These replace ad-hoc chain-level aggregates from legacy APIs with explicit, cacheable resources.
Euler Finance Curator API
Curator-managed metadata such as labels, descriptions, and visibility controls. This is the operator-owned customization surface in v3.
Euler Finance Earn API
Euler Earn vault resources and historical data. These endpoints are separate from EVK vaults and should be modeled independently in client code.
Euler Finance Entities API
Platform-admin managed KYBed organization profiles used as backend-owned label and control-plane resources.
Euler Finance EVC API
Ethereum Vault Connector account event resources. These are separate from account position snapshots and are intended for event-level inspection.
Euler Finance FeeFlow API
Fee-flow event resources and fee-related historical activity.
Euler Finance GraphQL API
Controlled GraphQL passthrough endpoints for indexer-backed data exploration and compatibility workflows.
Euler Finance Health API
Liveness, readiness, and dashboard-friendly platform status checks. Use these for operational monitoring, not for reconstructing full portfolio state.
Euler Finance Liquidations API
Liquidation events and related historical views used for risk analysis and monitoring.
Euler Finance Oracles API
Oracle routing, adapter, and price-source inspection endpoints. These expose pricing/oracle internals that were previously harder to inspect externally.
Euler Finance Prices API
Current and historical token prices. Prices follow v3 source priority rules and return the canonical merged value rather than exposing raw provider-specific reads by default.
Euler Finance Protocol API
Protocol-wide summary endpoints and aggregate metrics. In v3, these endpoints are explicitly summary-oriented and should be treated as lightweight rollups rather than replacemen...
Euler Finance PublicAllocator API
Public allocator event resources for allocator-level activity and history.
Euler Finance Rewards API
Reward campaign APRs and per-account reward breakdowns. Rewards APY is intentionally separate from base vault APY in v3; combine them client-side when you need a legacy-style to...
Euler Finance TermsOfUse API
Terms-of-use signature state and audit endpoints.
Euler Finance Tokens API
Token metadata, protocol classifications, and related static reference data used throughout the API.
Euler Finance Usage API
API usage and API key analytics. These endpoints are intended for operators and consumers tracking traffic, rate limits, and key-level activity.
Euler Finance Vaults API
Canonical vault resources, vault history, holders, borrowers, and open-interest views. In v3, vault detail is decomposed into focused endpoints instead of one large legacy respo...

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

Security Posture 3
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.

Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
