# Quickstart
> Make your first API-key call in minutes.
This gets you from a key to a live API call.
## 1. Get a key
Grab your Payments **test** key from the dashboard — see
[Get your API keys](/guides/api-keys). Then set your environment:
```bash theme={null}
export RACH_BASE="https://api.rach.finance/api/v1"
export RACH_KEY="test_sk_your_key_here"
```
## 2. Create a checkout
Accept a crypto payment with a hosted checkout (Crypto Gateway):
```bash cURL theme={null}
curl "$RACH_BASE/checkout/create" \
-H "X-API-Key: $RACH_KEY" \
-H "Content-Type: application/json" \
-d '{
"amount": 50,
"currency": "USD",
"reference": "order_1001",
"callback_url": "https://yourapp.com/webhooks/rach",
"payment_method": "crypto"
}'
```
```js Node theme={null}
const res = await fetch(`${process.env.RACH_BASE}/checkout/create`, {
method: "POST",
headers: { "X-API-Key": process.env.RACH_KEY, "Content-Type": "application/json" },
body: JSON.stringify({
amount: 50, currency: "USD", reference: "order_1001",
callback_url: "https://yourapp.com/webhooks/rach", payment_method: "crypto",
}),
});
console.log((await res.json()).payment_url);
```
```python Python theme={null}
import requests, os
r = requests.post(f"{os.environ['RACH_BASE']}/checkout/create",
headers={"X-API-Key": os.environ["RACH_KEY"]},
json={"amount": 50, "currency": "USD", "reference": "order_1001",
"callback_url": "https://yourapp.com/webhooks/rach", "payment_method": "crypto"})
print(r.json()["payment_url"])
```
```json Response theme={null}
{
"session_id": "cs_1a2b3c",
"payment_url": "https://api.rach.finance/pay/1a2b3c",
"amount": 50,
"currency": "USD",
"status": "pending",
"expires_at": "2026-08-14T13:00:00Z"
}
```
Redirect your customer to `payment_url`.
## 3. Confirm
Poll the session, or (better) receive a [webhook](/guides/webhooks) on settlement:
```bash theme={null}
curl "$RACH_BASE/checkout/verify/cs_1a2b3c" -H "X-API-Key: $RACH_KEY"
```
You just took a crypto payment in sandbox. Swap the `test_sk_` key for a `live_sk_` key to
go live — no code changes. See [Test vs Live](/guides/environments).
