}🟢get_cbi_quote(program, language, family)
Answers how much citizenship by investment or a second passport costs for a person or family, or compares programmes by total cost. Calculates the indicative cost for a family: government contribution, investment, fees, professional fees, payment phases and total in USD, plus which family members are eligible, processing time, page links and quoteRequestUrl. With one programme it returns that programme; without program it compares all 9 programmes (St Kitts and Nevis, Antigua and Barbuda, Dominica, Grenada, Saint Lucia, Vanuatu, Sao Tome and Principe, Nauru, Argentina). Figures are rounded indicative figures (total to the nearest 1,000 USD), binding only after a pre-check; the user receives the exact amounts by requesting the cost breakdown through quoteRequestUrl.

}🟢request_cost_breakdown_link(program, language, family, contact)
Returns only the personal link (quoteRequestUrl) for one programme and family: the calculator page on goodbyematrix.com with the family already filled in, where the user requests the detailed cost breakdown with the exact amounts by e-mail from the GoodbyeMatrix team. Contact details (first name, last name, e-mail, phone) are optional; only details the user has provided and wants to pass on are used. They prefill the form on that page and are never part of the link; the link works without them. The user checks the details and sends the request personally; the privacy consent is never preselected.
