# Retrieve fee estimates

Get what a send pays the network at each speed, and how long it takes.

`GET https://dash.402pay.co/api/v1/wallet/fee-estimates`

What a send from your wallet would pay the network at each speed, slowest first: `fee_usd` in US cents, and about how many `minutes` it takes. The fee is paid in the network's own coin, such as POL on Polygon, so sending a token needs some of that coin too. Sends take a person signed in to the dashboard, never an API key.

On a simulated business, the estimates are fixed.

### Query

- `network` (string, required): One of `solana`, `polygon`, `ethereum`, `tron`, `bitcoin`.

### Errors

- 400 `invalid_request` `network` is missing or isn't a network.

Any request can also fail on its key or its body. See [errors](https://developer.402pay.co/api/errors.md).
