PSA Population Report Scraper — Set Pop, PSA 10 & Gem Rate

Disclaimer: Unofficial tool for publicly accessible PSA population data. PSA, Professional Sports Authenticator, and Collectors are trademarks of their owners. Not affiliated with, sponsored by, or endorsed by PSA or Collectors Holdings. For informational, research, aggregation, and market-intelligence use only. Respect applicable terms of use and law.

PSA population report scraper for Pokémon TCG, Topps Chrome, and other graded-card sets. Use it as a PSA pop scraper, PSA pop API alternative, and set census export: paste a pop set URL, a heading ID, or a set name such as Surging Sparks. Dataset rows are one card variety each — PSA 10 pop, PSA 9, full grade ladder, gem rate, and optional monitor deltas. Fast HTTP JSON (GetSetItems) — no login field, no headless browser, no paid PSA Cert API. Call from Python, Node.js, cURL, or Apify MCP.

Built for card flippers who decide whether to submit raw copies, dealers watching gem-rate compression, and scheduled set monitors. The official cert API does not return population; this Actor reads the same public set-census JSON the pop report table uses.

When to use this Actor

• You need a PSA population report scraper / PSA pop API alternative that returns flat JSON rows
• You want bulk set pop (every card in Surging Sparks or Topps Chrome), not a single cert paste
• You track PSA 10 pop, gem rate, half-grades, and qualifiers for submit / buy decisions
• You scrape PSA pop with Python, Node.js, or MCP and export JSON / CSV
• You run a daily set monitor and want deltaPop10 / gemRateChange on a schedule

When not to use this Actor

• Single-slab cert verification — this Actor is a set census, not a cert lookup
• Guide prices / sold comps — use PriceCharting Scraper or eBay Sold Listings Scraper
• US live-commerce firehose — use Whatnot Listings Scraper
• Official PSA Public API replacement — cert fields still need PSA's cert API; pop is not in that API
• Buyer PII or submission accounts — public grade counts only

Key features

• Set URLs — paginate every card in a pop heading (full grade ladder)
• Set names — Surging Sparks and 2023 Topps Chrome resolve immediately; other names search public pop URLs
• Heading IDs — reuse IDs stored from a previous run
• Gem-rate fields — pop10, pop9, total, gemRate on every row
• Monitor mode — named Key-Value store of previous pops; later scheduled runs attach deltas
• Changed-only option — bill only spec IDs whose pop10 / total / gem rate moved
• Flipper filters — max PSA 10 pop, min/max gem rate, subject / variety contains
• MCP / AI ready — call from assistants via Apify MCP

FAQ

Does this replace the PSA Cert API?
No. Cert lookup is a different product. Population is not returned by the public cert API. This Actor scrapes set census rows.

Why not one cert number?
A flipper watching Surging Sparks needs every card's gem rate on a schedule. One-cert lookups do not retain. Use monitorMode on the set.

How big is Topps Chrome?
The 2023 baseball Chrome heading is tens of thousands of varieties. Leave maxItems at 500 for a sample, or set 0 only when you want the full dump.

Do I need a PSA login?
The HTML pop pages redirect to Collectors sign-in. This Actor calls the public GetSetItems JSON used by the table, so the input form does not ask for a password.
