Pendle Finance
Pendle Finance is a decentralized yield-trading protocol that tokenizes future yield by stripping yield-bearing assets into Principal Tokens (PT) and Yield Tokens (YT) wrapped in a Standardized Yield (SY) layer. PT trades at a discount and matures one-to-one for the underlying at expiry, giving buyers a fixed yield; YT entitles holders to the variable yield until expiry, letting them long, hedge, or speculate on yield itself. Pendle V2 pairs this with a purpose-built AMM for trading time-decaying assets, and Boros extends the design into a margin venue for trading yield as a perpetual rate. The protocol is live on Ethereum, Arbitrum, BNB Chain, Optimism, Base, Mantle, Sonic, Berachain, HyperEVM, Monad, Katana, and Ink. Developer surface includes the Pendle Hosted SDK (a REST API for generating Pendle transactions), a Backend Data API for market, asset, price, and governance data, Socket.IO real-time feeds, the Boros TypeScript SDK and Boros HTTP API, vePENDLE / sPENDLE governance, and audited open-source Solidity contracts for V2 cores, SY wrappers, and Boros core.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Pendle Finance the way a machine reads it — 45 machine-readable artifacts across 9 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 — Pendle Finance scores 15.5/100 (emerging), with a separate agent-readiness read of 7/100 (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.

APIs 9
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.

Standardized Yield (SY) Wrappers
ERC-5115 inspired wrappers normalize hundreds of LSTs, LRTs, stablecoin vaults, and RWA tokens into a single token interface that Pendle V2 markets and AMM understand.
Fixed Yield Trading
Buying PT at a discount locks in a fixed APY through expiry, regardless of how the underlying floating yield evolves.
Leveraged Yield Exposure (YT)
Buying YT gives capital-efficient long exposure to floating yield without holding the principal, used to long, hedge, or speculate on yield rates.
Time-Decay AMM
Purpose-built AMM that prices PT and YT against the underlying while accounting for time-to-expiry, supporting deep liquidity for yield trading.
vePENDLE Governance and Boosts
Locking PENDLE into vePENDLE grants governance power, voting on gauge weights, fee share, and LP yield boosts across markets.
Boros — Yield as a Perpetual

Security Posture 2
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.
