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 24.3/100 (emerging), with a separate agent-readiness read of 14/100 (agent aware). 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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Pendle Finance
Each block below is one kind of artifact we hold for Pendle 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 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.
Individual APIs this provider publishes, each with its own machine-readable definition.
Pendle Hosted SDK API

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.

This is an independent, third-party profile of Pendle Finance, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
