https://api.mtpelerin.com/currency_rates/convert (POST)

Parameter	Example value	Description
sourceCurrency	CHF	One of our supported fiat or crypto Chains and currencies.
destCurrency	BTC	One of our supported fiat or crypto Chains and currencies.
sourceAmount	100	Input amount. ⚠️ Do not use it at the same time as destAmount, or you will get a 400 error.
destAmount	100	Output amount. ⚠️ Do not use at the same time as sourceAmount, or you will get a 400 error.
sourceNetwork	fiat	One of our supported chains (see Tokens endpoint above), or 'fiat'.
destNetwork	bitcoin_mainnet	One of our supported chains (see Tokens endpoint above), or 'fiat'.
isCardPayment	false	'true' or 'false' if the payment will be made by card (only valid if sourceNetwork is fiat, ignored otherwise)

Response example:

{
  "fees": {
    "networkFee": "2.2605",
    "fixFee": 0
  },
  "sourceCurrency": "CHF",
  "destCurrency": "BTC",
  "sourceNetwork": "fiat",
  "destNetwork": "bitcoin_mainnet",
  "sourceAmount": 100,
  "destAmount": "0.00398660113390708486776"
}

"destAmount" is the net final amount, which includes all applicable fees.

The endpoint returns an error in case of an off-ramp if the amount is inferior the minimum amount of CHF 50 (or equivalent in other fiat currencies).

To know via API the minimum off-ramp amount, you can use:
