# Estimate Fee

**GET /wallets/{walletId}/delegation-fees**

<p align="right">status: <strong>stable</strong></p>

Estimate fee for joining or leaving a stake pool. Note that it is an
estimation because a delegation induces a transaction for which coins
have to be selected randomly within the wallet. Because of this randomness,
fees can only be estimated.

### 200: Ok

#### Body Parameters: application/json (object)
- **estimated_min** (object)
  Coins, in Lovelace. Only relates to 'Ada'. Refer to `assets` for multi-assets wallets instead.
- **estimated_max** (object)
  Coins, in Lovelace. Only relates to 'Ada'. Refer to `assets` for multi-assets wallets instead.
- **minimum_coins** (array[object])
  A list of minimum coin values that each output in a payment must satisfy. The values themselves depends on two things:

  - (a) Some updatable protocol parameters fixed by the network.
  - (b) The nature of the outputs (i.e. the kind of assets it includes).

The list is a direct 1:1 mapping of the requested outputs. Said differently, it has the **same number of items** and **items
are ordered in the same way** as **requested outputs** are ordered. In the case where there's no explicitly requested outputs (e.g.
when calculating fee for delegation), this list is empty.

For example, an output containing only `Ada` may require to be of at least `1 Ada`. An output containing only an hypothetical `AppleCoin`
may require to also carry a minimum of `1.2 Ada`. Note that no matter what, a minimum coin value is always given in Lovelace / Ada.

> ℹ️ This mechanism is used by the protocol to protect against flooding of the network with worthless assets. By requiring a minimum coin value to every
UTxO, they are given an intrinsic value indexed itself on the value of Ada.

- **deposit** (object)
  Coins, in Lovelace. Only relates to 'Ada'. Refer to `assets` for multi-assets wallets instead.
