Collectibles Market Research

Help with Collectibles Market Research tasks

Build evidence-backed briefs for trading cards and sports collectibles from public marketplace and PSA reference data. Keep identity, condition, grade, listing status, sale status, and source platform separate: an asking price is not a sale, and a PSA guide value is not a guaranteed market price.

When to use this skill

• Identify a card, set, subject, or certification and check PSA reference data.
• Compare live listings or auction lots across COMC, Fanatics Collect, ALT, Goldin, and Pristine Auction.
• Review sold-item evidence, auction history, market trends, or live-break inventory for a bounded collecting question.
• Build a short list of cards or lots with provenance, grade/condition, price, status, and the exact source URL.

Setup

• Get a Crawlora API key at crawlora.net.
• Set CRAWLORA_API_KEY in the environment before running the helper.
• The helper reads CRAWLORA_API_KEY from the environment and sends requests to https://api.crawlora.net/api/v1.

Research workflow

1. Normalize the target before searching: player/subject, year, brand/set, card number, parallel/language, grade, and whether the user wants live, sold, or auction evidence.
2. Use PSA discovery routes for categories, sets, checklists, and price-guide search. Use psa_cert_lookup only with a certification number; a cert result describes that cert and grade, not every copy of the card.
3. Search marketplaces with the narrowest supported terms and follow returned identifiers into listing/detail routes. Preserve the platform, listing type, asking/current bid/realized price, currency, condition, grade, and status.
4. Compare like with like: same card identity, grade, parallel, language, sale type, and time window. Deduplicate cross-posted items by source URL or platform id, but do not merge different sellers or platforms silently.
5. Report observed ranges and evidence counts. Separate PSA guide values, active asks, current bids, sold prices, and market-trend signals; do not claim a fair value, profit, rarity, authenticity, or investment return from a bounded sample.

Examples

scripts/crawlora.sh /psa/price-guide/search query="1986 Topps Jordan" | jq '.'
scripts/crawlora.sh /psa/cert-lookup cert_number=12345678 | jq '.'
scripts/crawlora.sh /comc/search query="1986 Topps Jordan" | jq '.'
scripts/crawlora.sh /fanaticscollect/sold-items title="Jordan" | jq '.'
scripts/crawlora.sh /goldin/auctions query="Mantle" | jq '.'
scripts/crawlora.sh /alt/market-trends | jq '.'

Limits

• Public data only; no account, purchase, bid, submission, authentication, or grading action is performed.
• Coverage, pagination, condition labels, fees, shipping, currency, and update times differ by platform. Say when a comparison is not apples-to-apples.
• PSA price-guide and population fields are source-specific reference signals; they do not establish a card's current sale value or guarantee authenticity.

Retail catalog context

PSAStore and PristineMarketplace expose storefront products and collections; Fanatics exposes sports-merchandise search and category/product detail. These are retail catalogs, distinct from PSA certification/price-guide evidence, Pristine Auction lots, and Fanatics Collect sold items. Discover collection handles or category URLs before retrieving products, and keep price, variant, stock status, and product condition separate from realized auction prices. PristineMarketplace search uses a fixed grid of at most 16 products per page even when a larger limit is requested. Do not infer complete coverage from a large requested limit. Reviews may describe the storefront, rather than the individual collectible. Merchandise availability does not prove authenticity or card rarity.
