Developers · Off-ramp API
Turn crypto into cash, programmatically
Accept crypto and convert it to the currency you hold via a single API call — settled to your regulated account, with a locked quote and clean compliance.
What it does
Built to drop in
Crypto → fiat in one call
Off-ramp USDT, USDC, BTC or ETH to the currency you hold — no exchange account.
Locked quotes
Lock a rate for the conversion so you know exactly what lands.
Settles to your account
Cash arrives in your multi-currency 1klas account, T+1.
Screening built in
Source-of-funds and sanctions screening — a rail your bank respects.
How it works
Three steps to live
01
Request a quote
Ask for a locked rate and a deposit address.
02
Send the crypto
Transfer to the address you’re given.
03
Receive cash
A webhook fires; the fiat settles to your account.
offramp.js
const order = await klas.offramp.create({
asset: "USDT", amount: 5000,
settle_currency: "EUR" // lands as cash
})
// send crypto to order.deposit_address
// webhook: offramp.settled -> cash in your account
