- Base URL: `https://svc.blockdaemon.com`
- URL: `https://svc.blockdaemon.com/defi/v1/yieldaggregator/redeem`
- Auth: API key in header `X-API-Key`

> 💡 
**Compute Unit Value:** `40` (Fixed)

## Request body

- YieldaggregatorRedeemRequest: The request body for a /defi/v1/yieldaggregator/redeem
  - `yieldAggregatorId` '5200' | '5201' | '5202' | '5203' | '5204': The unique identifier used to route queries or transactions to the correct yield aggregator.
  - `tokenOut` string, required: The token to be received upon withdrawal.
  - `amountIn` string, required: Amount of the input token to provide, specified in the token's smallest denomination (base units). Do not send human-readable decimal values. Examples: to swap 1 WETH (18 decimals), use "1000000000000000000"; to swap 1 USDC (6 decimals), use "1000000".
  - `from` string, required: Blockchain address of the sender. For EVM chains, use a checksummed hex address (e.g., 0xABCDEF...). This address must hold sufficient balance and will sign the transaction.
  - `gas` string: Maximum number of gas units to allocate for the transaction, as an integer string (e.g., '200000'). If omitted, gas is estimated automatically. Note: this is gas units, not wei or gwei.
  - `slippage` string: Optional slippage tolerance for the transaction. Valid range: 0 to 100 (e.g., 1 = up to 1% slippage).
  - `ytAddress` string, required: The blockchain address of the yield token. You can provide this parameter using either 'ytAddress' (yield token address) or 'syAddress' (standard yield address). Both names are accepted and refer to the same value.
  - `syAddress` string, required: The blockchain address of the yield token. You can provide this parameter using either 'ytAddress' (yield token address) or 'syAddress' (standard yield address). Both names are accepted and refer to the same value.
  - `enableFee` boolean: Flag to include a basis points fee transaction alongside the main transaction when set to true.

## Response `200`

Successful response

- object
  - `status` integer
  - `msg` string
  - `data` object
