Introduction#

DeFi API is a core infrastructure module of OnchainOS, providing DeFi users with comprehensive DeFi investment capabilities — product discovery, trade execution, and position management, all through a single interface that covers mainstream DeFi protocols.

  • Product Discovery — Query investment products across dozens of DeFi protocols such as Aave, Lido, and more. Retrieve detailed product information including APY, fees, total value locked, etc.
  • Trade Execution — Subscribe to or redeem investment products, lend or repay assets, and claim related investment rewards.
  • User Holdings — Query DeFi investment position details across chains and protocols, with real-time tracking of principal, earnings, APY, and other relevant data.
