Market Movers Scraper 🏀🃏 — sports-card catalogue, market prices, sales comps & live listings

Reads Sports Card Investor / Market Movers' own mobile API directly (the app's anonymous tRPC backend), so it's fast and complete — no HTML scraping, no login. Read-only public data. Export to JSON, CSV, Excel, or an API.

Modes

• search (default) — search the card/item catalogue by keyword and filters. Every result carries the card's attributes (player, set, sport, grade, variation, rookie, image) plus market-price stats across last7 / last30 / last90 / last365 / all windows (avg/min/max, sales count, change).
• completedSales — completed sales comps for one or more collectible ids (final price, date, platform, seller, bids, sale URL).
• activeSales — live marketplace listings (eBay, Goldin, MySlabs, …) for collectible ids (buy-it-now/auction price, marketplace, end time).
• dailyStats — per-collectible daily price stats for collectible ids.
• deals — the app's "great deal" listings feed.
• marketIndices — curated market indices (SCI 500, …); set indexId (+ startDateISO) to also pull that index's stats series.
• reference — lookup lists: sports, grades, sale platforms, and platform-wide totals.

Every row shares one flat schema with a type discriminator, so a mixed export stays a single table; fields that don't apply to a row type are null. Prices are USD dollars as returned by the API.

📤 Output

A flat record per item with a type discriminator. Collectible rows carry player, set_name, set_year, sport, grade, set_variation, price_*_avg, population_count and the full nested stats. Sale rows carry final_price/sale_price, sale_platform/marketplace, sale_date, seller_name, url. Reference rows carry name/id. Shapes that vary (deals, daily stats, index stats, platform totals) also include the raw object under data.

📌 Good to know

• No login. The app's public.* API is anonymous; this is exactly the public market data the app shows a signed-out user. There is no request signing or API key on this surface.
• Prices are the app's own compiled market data. Market Movers itself aggregates sales from eBay, Goldin and other auction houses; this actor reads the app's API rather than those upstream sources (which sit behind Akamai/Cloudflare bot walls). Values are point-in-time.
• Proxy. Apify datacenter proxy is on by default to keep requests off the run's shared IP; the API is not geo-gated, so datacenter is enough (no residential needed).
