For the complete documentation index, see llms.txt. The Payments API (https://payments.shakesco.com) gives your backend full programmatic control over invoices, customer analytics, and store items. Use it to automate billing, build dashboards, or sync your catalogue.
All API calls require your API key. Get it from users.shakesco.com/user/api-tokens.

    currency: "USD",
    payer_email: "customer@example.com",
    items: [{ description: "Consulting", unit: 5, price: 100 }],
