NorthFond publishes machine-readable documentation for AI coding assistants:
llms.txt is the compact documentation index.llms-full.txt contains the complete published documentation corpus.openapi.json is the canonical request and response contract.
Use the Copy page, View as Markdown, Open in ChatGPT, or Open in Claude action at the top of a documentation page when you need focused context.
Recommended prompt
Give AI only test credentials
Do not paste a raw API key into a chat, issue, source file, or generated prompt. Store the sandbox key in a local secret manager or environment variable and let generated server-side code read NORTHFOND_API_KEY at runtime.
Review generated code before running it. An AI assistant must not decide when to enable live credentials, weaken webhook verification, remove idempotency, or fulfill an order from a browser redirect.
Contract boundaries
The OpenAPI specification documents API-key-authenticated Business API endpoints. Hosted payment-page endpoints are customer-facing and are documented in Payment links. Payroll is currently a Business dashboard workflow and is not part of the public Business API.
Runtime availability can differ by business, environment, policy, country, payment method, and provider readiness. Query the relevant capability or readiness endpoint rather than asking an AI assistant to hardcode a country list.
