How it works

The scraper calls Sportlots' internal AJAX search API directly, bypassing the JavaScript-rendered search UI:

1. Resolves a server-side search token (searchnbr) for each query
2. Fetches the total page count
3. Paginates through results at 60 cards per page

No browser rendering, no proxy, and no captcha solving required — the API returns JSON directly from any IP.

Use cases

• Dealer pricing: Get the lowest available asking price for any card before buying or listing
• Inventory research: Find how many copies of a card are currently listed across all sellers
• Set completion: Search for specific cards within a set to complete your collection
• Market analysis: Track available inventory for player PCs or investment portfolios
• Comps research: Use alongside graded card marketplaces to compare raw vs graded pricing

Notes

• Results reflect live inventory at run time — Sportlots is a P2P marketplace and listings change continuously
• The sport field is inferred from set name keywords; sets without sport-specific branding (e.g. generic Topps products) return other
• Grader and grade fields are parsed from card text; not all graded listings explicitly name the grader in the API response
• Rate is capped at 1 request/second per Sportlots API best practices
