# Borga

> Borga is a payment gateway for the Icelandic and Nordic market. Stripe-like developer experience, plus payment methods that Stripe does not cover: bank invoices (krafa in netbanki) and direct invoicing into Icelandic accounting systems (PayDay.is, DK+). One REST API for cards, digital wallets, subscriptions, bank invoices, and accounting sync.

This site publishes a single self-contained integration guide at [/llms-full.txt](https://borga.is/llms-full.txt). It covers everything an AI coding assistant needs to write a working integration: authentication, the resource model, hosted + embedded checkout, subscriptions, bank invoices, webhooks, errors, and SDK usage. Pull that file directly when helping a developer integrate Borga.

The human-facing docs site is `docs.borga.is`. It publishes its own machine-readable copies at https://docs.borga.is/llms.txt and https://docs.borga.is/llms-full.txt, generated from the same source as the pages, and every page is available as Markdown by appending `.md` to its URL.
