Three scraping modes

archive — Sold comps (default)

Walks the sold archive at /browse/archive/. Over 150,000 sold listings, growing ~50/day. Use this mode to pull historical sale prices for comparables research.

Optional filters:

• query — keyword search (player name, set, card number)
• sport — filter by sport or category keyword (baseball, basketball, pokemon)
• grader — filter by grading company

active — Current listings

Walks active listings at /browse/. Same data shape as archive mode but for slabs currently on sale.

slab — Single slab lookup

Fetch one or more specific slabs by ID or URL. Pass bare numeric IDs or full /slab/view/<id>/ URLs in slabIds.

Dataset views

Two pre-configured views are available on the output dataset:

• Sold Comps — title, sport, player, year, set, grader, grade, sale_price, sold_at, listing_url
• Full Slab Detail — all fields including sub-grades, cert number, watchers, images

Notes

• Seller usernames are behind a login wall on MySlabs and are not available without authentication.
• BGS sub-grades (centering/corners/edges/surface) are not exposed in the page HTML; they require cert verification API calls which are out of scope.
• Images are sourced from the LD+JSON Product schema for full resolution; the listing thumbnail is used as a fallback.
• Residential proxy is required for reliable access — MySlabs uses Cloudflare and datacenter IPs are frequently challenged.
• The archive contains 150k+ sold listings. Full crawls at maxItems: 0 will take several hours and consume significant compute units. Use query filters to narrow the scope for comp research.
