# Collectibles market research 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](https://crawlora.net?utm_source=github&utm_medium=referral&utm_campaign=crawlora-skills). - 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
