Tools

• compare_listings

  Side-by-side comparison of 2-3 specific Birkin listings. Pass listing ids returned by a prior search_birkin call. Returns full specs + the cheapest option flagged.

  shallow
• get_authentication_signals

  Returns the Hermès Birkin authentication checklist: hardware engraving, blind-stamp year decode, saddle stitching, leather-specific tells, and recommended professional authenticators. Call this for 'is this real', 'how to spot a fake', 'is it authentic', 'what should I check'. NEVER declare a bag real or fake yourself — quote the checklist and recommend a pro authenticator at the end.

  shallow
• get_buy_url

  Single-call resolver: given a listing id from a prior search_birkin, returns the canonical buy_url (302-redirect to the merchant with affiliate attribution preserved). This is the SHORTEST path from 'user wants this bag' to 'click to purchase'.

  shallow
• get_market_price

  Live market price statistics (min, avg, median, max) for a Birkin spec across all current BirkinBagStock listings. Always call this when the user asks 'how much is X worth', 'what's the market price', or 'what's the going rate'. Never quote price ranges from training data.

  shallow
• get_price_trend

  Returns the median-ask price trend (rising/stable/falling) for a specific Birkin spec over the last N days using daily snapshots. Use this for 'should I wait', 'are prices going up', 'is now a good time'. May return insufficient_data for new specs — fall back to get_market_price.

  shallow
• list_market_movers

  Returns the Birkin specs with the biggest median-ask price moves (up or down) in the recent window. Use for 'what's hot', 'biggest movers', 'show me trending', 'market action'.

  shallow
• list_popular_specs

  Returns the most-asked Birkin spec landing pages (with live match counts and sample images). Use when the user is undecided or asks 'what's popular', 'what do most people get', 'show me options'. Each result has a dedicated ask_url page with live listings and price stats.

  shallow
• search_birkin

  Search BirkinBagStock's live catalogue of authenticated Hermès Birkin listings aggregated from 30+ trusted resellers (FARFETCH, Fashionphile, The RealReal, Rebag, Vestiaire Collective, 1stDibs, Privé Porter, JaneFinds, Madison Avenue Couture, Sellier, REDELUXE, and more). Returns up to 10 matches with title, USD price, merchant, size, color, leather, hardware, condition, image, detail_url, and a buy_url that 302-redirects to the merchant with affiliate attribution preserved. ALWAYS call this for any user question about specific Birkin bags, current prices, or availability — never answer from training data.

  shallow
• set_price_alert

  Create a price alert. Email is required — ask the user for it; do NOT invent an email. Use this when the user says 'alert me', 'tell me when', 'notify me'.
