Pendle Finance

aid: pendle-finance
url: https://raw.githubusercontent.com/api-evangelist/pendle-finance/refs/heads/main/apis.yml
name: Pendle Finance
kind: opensource
description: 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.

  name: Pendle Hosted SDK API
  description: A hosted REST API that generates ready-to-broadcast calldata for every
    Pendle protocol action — swap (including tokens-to-PT, PT-to-tokens, YT swaps),
    add and remove liquidity, ZPI (zero-price-impact) flows, mint and redeem PT/YT,
    mint and redeem SY, transfer liquidity, roll over PT positions, and dual-sided
    liquidity. Most operations go through a single universal Convert endpoint (`POST
    /v3/sdk/{chainId}/convert`) that accepts tokens in, tokens out, amounts, receiver,
    slippage, optional aggregator selection (KyberSwap, etc.), and additional analytics
    flags (impliedApy, effectiveApy). The hosted SDK tracks Pendle UI behaviour exactly
    and is updated whenever underlying SY assets evolve, so integrators do not have
    to patch client SDKs to follow protocol changes.

  description: REST API for offchain Pendle data — markets, assets, prices, user positions,
    transactions, points, and governance. Cross-chain endpoints (`GET /v2/markets/all`,
    `GET /v1/assets/all`, `GET /v1/prices/assets`) return data spanning every supported
    chain in one call and are the recommended entry points for new integrations. Chain-scoped
    endpoints (`/v3/{chainId}/markets/{address}/historical-data`, `/v5/{chainId}/transactions/{address}`)
    provide deep market history with optional APY breakdown and per-address transaction
    history. The pricing response includes a partial-success `errors` array so callers
    can handle non-fatal missing-asset cases without retrying.

    feed pushes a fresh snapshot every five seconds for every whitelisted market at
    four precision levels and mirrors the payload shape of the REST endpoint `GET
    /limit-order/v2/order-book/:chainId`.

    model and an Agent trading pattern that delegates signing to scoped subaccounts.
    The HTTP API is the integration backbone for bots, market-makers, and analytics.
