Use the Onramp Quotes APIPublic preview
Display quotes in your product UI.
The Onramp Quotes API lets platforms fetch estimated quotes for onramp conversions into various cryptocurrencies on different networks. You can specify a fixed source or destination amount and limit the quotes to a subset of destination currencies or networks. This API allows you to display quotes in your product UI before directing the user to the onramp widget. If the quote expires before the user visits the onramp widget, the user might see a slightly different quote in the onramp widget.
Get a conversion quote 
Use the GET /v1/crypto/onramp_ endpoint to get a conversion quote. The following table captures all of the available parameters for this endpoint:
| Parameter | Type | Default | Details |
|---|---|---|---|
source_ | String (optional) | usd | The ISO-4217 currency code. We currently only support usd and eur. |
source_ | String (optional) | 100. | A string representation of the fiat amount that you need to onramp. If source_ is set, destination_ must be null (they’re mutually exclusive, because you can only set a fixed amount for one end of the trade). |
destination_ | String (optional) | null | A string representation of the amount of destination_ to be purchased. If destination_ is set, source_ must be null. When specifying this field, you must also set a single value for destination_ and a single value for destination_ (so we know what cryptocurrency to quote). |
destination_ | Array<String> (optional) | null
| The list of cryptocurrencies you want to generate quotes for. If left null, we retrieve quotes for all destination_ that destination_ supports.
|
destination_ | Array<String> (optional) | null
| The list of cryptocurrency networks you want to generate quotes for. If left null, we retrieve quotes for destination_ in all networks.

To fetch quotes for ETH and SOL on the Ethereum and Solana networks, run the following command (which results in ETH on Ethereum and SOL on Solana). When you specify destination_ and destination_, each valid currency-network pair in their cross-product returns a quote. The default value for destination_ is all currencies, and the default value for destination_ is all networks.
