In this guide, you’ll create your first “onramp” transaction — converting fiat currency to cryptocurrency. Let’s create an onramp converting 100 USD to USDT.
1

Create a quote

To create a quote, you need to use the /quotes endpoint. This will give you the current conversion rate for the given source and destination assets.

​
Request Example

curl --request POST \
  --url https://api.conduit.financial/quotes \
  --header "X-API-Key: your_api_key" \
  --header "X-API-Secret: your_api_secret" \
  --header "Content-Type: application/json" \
  --header "Api-Version: 2024-12-01" \
  --data '{
    "source": {
      "asset": "USD",
      "amount": "100.00"
    },
    "target": {
      "asset": "USDT",
      "network": "tron"
    },
  }'

​
Response Example

{
  "id": "quote_2fvietuCNSu8unMNLsEGBrDTVFn",
  "source": {
    "amount": "100.00",
    "asset": "USD"
  },
  "target": {
    "amount": "99.50",
    "asset": "USDT",

  "expiresAt": "2024-10-27T00:03:00.000Z"
}
Success! Save this quote_id - you’ll need it for transactions.

Create an onramp transaction

To create a onramp transaction, you need to use the /transactions endpoint. This will create a transaction where you are converting fiat currency to crypto currency.

  --header "X-API-Key: your_api_key" \
