AntikFinder — AI-Enhanced Antique Market Calendar (PoC)

Concept

Niche: Regional antique market calendar for the DACH region (Germany, Austria, Switzerland) with an AI layer on top
Thesis: Existing antique market calendars are plain "calendar dumps" built on 2010s technology. Nobody has AI. The high-spending 50+ target demographic is completely underserved.

What This PoC Demonstrates

A user uploads a photo of an antique → Claude Vision identifies the period, style & market value → Affiliate links to eBay, Catawiki, and Pamono are generated automatically.

User uploads photo
    ↓ POST /api/identify
route.ts → convert to base64
    ↓
claudeIdentify.ts → Claude Opus 4.7 (Vision)
    ↓ structured JSON
{title, period, style, valueRange, searchTerms, confidence}
    ↓
affiliateLinks.ts → generate 3 tracking URLs
    ↓
UI shows: object details + 3 CTA buttons (eBay / Catawiki / Pamono)

Market Analysis

Competitors (DACH)

Platform	Strengths	Weaknesses
meine-flohmarkt-termine.de	Large DB, DE/AT/CH	No AI, no photo, 2005 UI
marktcom.de	App available, 30 categories	No recommendations, no price context
melan.de	4M visitors, 1,500 events/year	Own events only, not an aggregator
Antiques Atlas (UK)	Best search depth, dealer profiles	UK only, no DACH

Conclusion: Nobody has AI. Clear market gap.

Monetization Strategy

Phase 1 — Affiliate (Day 1)

Platform	Commission	Network	Cookie	Requirements
eBay EPN	3% on antiques (max. €550)	Direct (EPN)	24h	Instant, no traffic minimum
Catawiki	€40 per new customer	Partnerize	30–60 days	Website required
Pamono	5–7% by volume	FlexOffers	n/a	Website + approval

Mechanic: Photo upload → AI identifies object → affiliate links to matching search results

Phase 2 — B2B Organizers (Month 3)

• Base: free listings
• Premium (€29–€79/month): featured placement, AI-generated event descriptions, statistics

Phase 3 — Premium Users (Month 6)

Tier	Price	Features
Free	€0	Calendar, 3 photo scans/month
Collector	€7/month	Unlimited scans, alerts, route planner
Dealer	€29/month	Dealer profile, inventory AI, analytics

Unit Economics (example at 1,000 active users)

300 Collector users × €7/month   = €2,100
50 premium organizers × €49      = €2,450
Affiliate (conservative)          = €1,500
                                   ───────
                                   ~€6,000/month

Installation & Setup

1. Install dependencies

npm install

2. Set environment variables

cp .env.local.example .env.local

Edit .env.local:

# Required
ANTHROPIC_API_KEY=sk-ant-...

# Optional — affiliate links work without these, but without tracking
EBAY_CAMP_ID=YOUR_CAMPAIGN_ID

3. Start dev server

npm run dev
# → http://localhost:3000

Activating Affiliate Programs

Platform	Steps	Time
eBay EPN	partnernetwork.ebay.com → add Camp ID to .env.local	10 min
Catawiki	join.partnerize.com/catawiki → replace tracking prefix	30 min
Pamono	flexoffers.com → wait for approval, then replace URL	1–7 days

Links work without affiliate IDs — they just forward without tracking.
