How it works

Live in an afternoon.

No SDK to install and nothing to host. Three steps from sign-up to your first payment.

1

Create an account

Sign up with your email and add a merchant for your store. No credit card, no paperwork.

2

Create an invoice

One API call from your checkout, or one click in the dashboard. Price it in USD or in crypto.

POST /v1/invoices
{ "priceAmount": "120.00", … }
3

Get paid

Your customer pays on the hosted page. You get a signed webhook and the money in your balance.

Everything a checkout needs. Nothing it doesn’t.

Fresh address per invoice

Every invoice gets its own address, so payments match exactly. No memo or tag for customers to forget.

Price in USD

Set a dollar price and the rate locks when the invoice is created, or ask for an exact crypto amount.

Hosted checkout

QR code, countdown, a wrong-network warning and live confirmations, on every chain and every phone.

Reorg-safe crediting

Payments count at a safe depth and become withdrawable at full finality. A reorganised block is reversed automatically.

Signed webhooks

Every invoice and withdrawal change is sent to your server, signed, and retried until it lands.

Withdraw anytime

Send your balance to any address on the same network. The network fee is quoted before you confirm.

For developers

One API call to get paid.

Plain REST and JSON. Amounts are exact decimal strings, never floats, and idempotency keys make retries safe.

  • API keys per merchant, with IP allowlists
  • An OpenAPI 3.1 spec for every endpoint
  • Webhooks you can verify with your signing secret

0.5% per payment.

No setup fee and no monthly fee. Customers pay the network fee when they send, and every withdrawal shows its network fee before you confirm.
