DeFi Data

DeFi Protocols Collateral Information

GET https://api.diadata.org/v1/synthasset/:blockchain/:protocol

The endpoint provides information on the health factor of DeFi protocols.

It takes into consideration outstanding loans, contracts' balance and compares it to synthetic token issuance. This helps to make sure that all assets are fully collateralized.

Exemplary query:

https://api.diadata.org/v1/synthasset/Ethereum/Aave-V2

Currently only Aave V2 and Aave V3 are supported on Ethereum and Avalanche blockchains.

It is possible to receive collateral information for a single token by using token filter as in example below:

https://api.diadata.org/v1/synthasset/Avalanche/Aave-V3?address=0xB31f66AA3C1e785363F0875A1B74E27b85FD66c7

To receive all asset updates data during the selected period use starttime and endtime filter parameters with timestamps as inputs. Here is an example:

https://api.diadata.org/v1/synthasset/Avalanche/Aave-V3?address=0xB31f66AA3C1e785363F0875A1B74E27b85FD66c7&starttime=1664502770&endtime=1664531570

Path Parameters

Name	Type	Description
blockchain*	String	Ethereum or Avalanche
protocol*	String	Aave
address	String	Token contract address. You can use either underlying token address or synthetic token to receive the data
starttime	Integer	Unix timestamp setting the start of the return array

Slippage calculation (for Uniswap V2 and its forks)

GET https://api.diadata.org/v1/poolSlippage/:blockchain/:pool_address/:token1_address/:pool_type/:desired_slippage

To predict the amount of tokens required to reach a specified slippage, you can use Pool Slippage endpoint. It works for any pool that exists on Uniswap V2 or any fork DEX on supported list of exchanges.

Here is an exemplary API call:https://api.diadata.org/v1/poolSlippage/Ethereum/0xb4e16d0168e52d35cacd2c6185b44281ec28c9dc/0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48/UniswapV2/100

The logic is as follows:

Provide the address of the pool, select a token in which you wish to have slippage calculated (e.g. if selected ETH from ETH-USDC, it will show how much is ETH is required to move the price by selected amount) and determine the goal for price movement.

Path Parameters

Name	Type	Description
:blockchain*	String	Name of the blockchain of the requested pool (e.g. Ethereum, Moonbeam, etc.)
:pool_address*	String	Address of the requested pool
:token1_address*	String	Address of either of the tokens in the pool
:pool_type*	String	Type of the pool (e.g. UniswapV2)
:desired_slippage*	Integer	Per mille (e.g. 100 will result in 10% slippage)
