info

Lido APIs are strictly for read-only access

Here you can find various Lido APIs which you can integrate in your app or website:

Lido APR​

API provides Ethereum and Lido staking APR, which include:

Simple Moving Average Lido APR for 7 last days:​

This APR value is based on Simple Moving Average of APR values over a period of 7 days.

https://eth-api.lido.fi/v1/protocol/steth/apr/sma

Response schema and examples are available in the Swagger API documentation

Last Lido APR for stETH​

The latest staking APR value. For Lido V1, we collected APR values by periodically fetching oracle report events. For the V2 version, the value is calculated based on rebase events.

V2 APR calculation:

// Emits when token rebased (total supply and/or total shares were changed)
event TokenRebased(
    uint256 indexed reportTimestamp,
    uint256 timeElapsed,
    uint256 preTotalShares,
    uint256 preTotalEther, /* preTotalPooledEther */
    uint256 postTotalShares,
    uint256 postTotalEther, /* postTotalPooledEther */
    uint256 sharesMintedAsFees /* fee part included in `postTotalShares` */
);

preShareRate = preTotalEther * 1e27 / preTotalShares
postShareRate = postTotalEther * 1e27 / postTotalShares

userAPR =
    secondsInYear * (
        (postShareRate - preShareRate) / preShareRate
    ) / timeElapsed

Lido Reward History​

Reward History Backend provides an API which returns all stETH interactions by an address and calculates its daily stETH rewards.

Currently, there's just one endpoint (/):

https://reward-history-backend.lido.fi/?address=0x12345

Response schema and examples are available in the Swagger API documentation

Parameters​

The only required query parameter is address.

Optional Parameters:

  • currency: USD/EUR/GBP - Fiat currency in which to display stETH denominated in fiat. USD by default.
  • archiveRate: true/false - Use an exchange rate close to the transaction time when calculating currency values instead of the current one. true by default.
  • onlyRewards: true/false - Include only rewards without transfers or stakings. false by default.
  • sort: asc/desc - Sort of transactions by blockTime. desc by default.
  • skip: number - Amount of data items to skip.
  • limit: number - Maximum amount of data items to respond with.

skip and limit params are used for pagination eg:

skip: 0, limit: 100 = 1 page
skip: 100, limit: 100 = 2 page
skip: 200, limit: 100 = 3 page

Holesky​

Reward History Backend is also available on Holešky:

Withdrawals API​

The Withdrawals API service offers an utility for estimating the waiting time for withdrawals within the Lido on Ethereum protocol. The service is helpful for stakers, providing insights from the moment of withdrawal request placement to its finalization when the request becomes claimable.

See the detailed explanation.

Use Cases​

  • Estimation before request: users can estimate the waiting time before placing a withdrawal request.
  • Tracking the existing request: users can track the estimated waiting time for the already placed request.
