Anytime Capital Payments lets a verified business take payments by payment link, invoice, a Pay button on its own website and QR code in person, then pay the money out from one balance. Online card payments are 2.75% + 30¢, and you can start without writing code: everything here is also in the dashboard.

What you can build
- Payment links: a hosted checkout page for one price, made in the dashboard or with
POST /api/v1/payment-links, shared anywhere or created per order. - Invoices: line items, tax, deposits and reminders, emailed in your branding and paid by card.
- Website checkout: a Pay button that opens checkout over your page, or the checkout inline, in a few lines of HTML.
- In person: key in an amount, show a QR code, and the customer pays on their own phone. No card reader.
- Automation: read payments and customers, and react to payments, refunds, disputes, invoices and subscriptions by webhook.
- AI agents: let Claude or another assistant create links and invoices and look up payments through the MCP server.
