Discover today's best deals ranked 0–100 — answer "what are the best deals right now?" without a specific product, ACROSS EVERY VERTICAL. `surface` selects the inventory: shopping (default — retail deals by stored deal score), hotels (biggest 7-day nightly-rate drops), events (activity rate drops), tickets (live-event tickets priced below their 30-day median, with a reasons[] breakdown), or all (one response grouped into labeled per-surface sections — hotels, things to do, event tickets, shopping). Rows carry a drillDownTool for the next call (hotel_details / activity_details / ticket_details / price_check). Optional `category` filter (shopping only) and `minDealScore` (shopping defaults to 60; other surfaces filter only when provided). URLs are pricetik.com/go/ affiliate redirects — pass them to the user's browser unchanged, do not fetch them server-side. No API key required. For a specific query use pricetik_search; for deals ranked to the user's stated interests use pricetik_deals_for_you.
