Pendle Finance

Pendle Hosted SDK API

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.
