purpose
Ironfang is a suite of UK-built developer APIs covering six products: Render (URL/HTML to PDFs and screenshots), Finance (e-invoice validation for Peppol, XRechnung, ZUGFeRD), Audit (website change monitoring with history), Analytics (session replay), Rig (integration testing with temporary inboxes and webhooks), and Security (external domain checks for DNS, TLS, headers and email). All products are managed through a single account, dashboard, and monthly invoice.
when to use
This resource is most valuable when a product needs capabilities such as document rendering, invoice compliance validation, change detection, session analytics, or external security auditing, and the team wants to avoid operating browser infrastructure or building validation logic in-house. It is especially useful for teams with UK/EU e-invoicing compliance requirements or those seeking a single vendor for multiple utility APIs.
