主要エンドポイント
/psa/cert-lookupLooks up PSA's own public Cert Verification record for one PSA-graded card by its certification number: item title, grade, label type, reverse cert/barcode flag, year, brand/title, subject, card number, category, PSA's own price estimate, and this-cert's-own population figures (population for this exact card+grade, and pop-higher). Scoped to PSA's trading-card department; a cert number issued under a different PSA division (autographs, tickets) returns a not-found error. PSA's full Population Report and Auction Prices Realized both require a PSA/Collectors account login and are not available through this endpoint.
レスポンスに関する注記
- A successful lookup is cached for up to 6 hours, so `psa_estimate` and the population figures can be that old on a repeat request. An uncached lookup typically takes 5 to 30 seconds. - `psa_estimate`, `psa_population`, `psa_population_url` and `psa_pop_higher` are omitted when PSA shows no figure for a given field on this cert (e.g. an ungraded/authentic-only item carries no PSA Estimate). - `psa_population_url` is PSA's own Population Report deep link for this card+grade, informational only — following it requires a Collectors account login. - `label_type` is empty when the cert carries PSA's standard label (no special label variant like Fugitive Ink or a Black Label-style qualifier). - A cert number PSA cannot resolve (invalid, or issued under a non-trading-card department) returns `404`.
MCPツール psa_cert_lookup
/psa/price-guide/categoriesPSA Price Guide's full category list -- the discovery endpoint for the category_path parameter used to browse or fetch a set's price table. Every category is a distinct collectible type (Baseball Cards, Basketball Cards, Boxing Cards, Football Cards, Golf Cards, Hockey Cards, Soccer Cards, Non-Sports/TCG Cards, Racing Cards, Sports Tickets, Tennis, Unopened Packs, Presidential Autographs, Sports Autographs, Professional Model/Game-Used Bats, Graded Baseballs).
レスポンスに関する注記
- `path` is the category segment of the URL of the sets inside it, so use the returned value verbatim as `category_path` for `psa-price-guide-set` and `psa-price-guide-sets`. It is not a uniform slug+id template: most categories end in `-values`, but `non-sports-tcg-card-values`, `game-used-bat-values` and `graded-baseball-values` differ from the older slugs PSA's navigation links redirect from, and Presidential Autographs and Graded Baseballs each hold a single set.
MCPツール psa_price_guide_categories
/psa/price-guide/searchSearches PSA Price Guide by free text (a player/subject name or set name), matching PSA's own site search box. Each result is a matching set with the query's matching cards/items inside it; use a result's category_path, set_path and set_id as the input to psa-price-guide-set to fetch that set's full price table.
レスポンスに関する注記
- If this endpoint returns a `503` because PSA's own search is unavailable, use `psa-price-guide-sets` to find a set by name instead; it does not match card or player names. - Use a result's `category_path`, `set_path` and `set_id` as the input to `psa-price-guide-set` to fetch that set's full price table. - `items` lists only the cards within that set that matched the query, not the set's full checklist — call `psa-price-guide-set` for the complete set.
MCPツール psa_price_guide_search
/psa/price-guide/setsSearches PSA Price Guide by set name (for example "1974 topps" or "super bowl") using PSA's own browse-by-category pages. It matches set names only: it does not search card or player names, and results carry no card items. Use psa-price-guide-search for card and player search while PSA's own search is available. Every word of the query must start a word of the set name; exact and leading matches rank first. Each result's category_path, set_path and set_id are the inputs to psa-price-guide-set. Set lists are cached for 12 hours, so a first call after a cold start can take longer. If a category's set list cannot be loaded, the other categories still answer and unavailable_categories names the missing ones.
レスポンスに関する注記
- Use a result's `category_path`, `set_path` and `set_id` as the input to `psa-price-guide-set` to fetch that set's full price table. - Ranking: sets whose name equals the query come first, then names that start with the query, then the rest in PSA's own order. - `total_count` is every match across all pages. A query with no match returns `200` with `total_count` 0 and an empty `sets` list. - Each category's set list is cached for 12 hours, so the first call after a quiet period (or a restart) can be slower than later ones. The 16 categories hold about 2,900 sets; new sets appear after the cache refreshes. - If one category's set list cannot be loaded, the other categories still answer and `unavailable_categories` names the missing ones, so `sets` and `total_count` cover the remaining categories only. A request fails with `503` only when no category could be loaded. - `category_name` is the category's display name from `psa-price-guide-categories`, for example `Baseball Cards`. Example response (a live `query=1974 topps` result, checked 2026-10-25): ```json { "code": 200, "msg": "OK", "data": { "query": "1974 topps", "page": 1, "page_size": 50, "total_count": 6, "sets": [ { "set_id": 1239, "set_name": "1974 Topps", "category_name": "Baseball Cards", "category_path": "baseball-card-values", "set_path": "1974-topps" }, { "set_id": 1708, "set_name": "1974 Topps", "category_name": "Basketball Cards", "category_path": "basketball-card-values", "set_path": "1974-topps" }, { "set_id": 694, "set_name": "1974 Topps", "category_name": "Football Cards", "category_path": "football-card-values", "set_path": "1974-topps" }, { "set_id": 1576, "set_name": "1974 Topps", "category_name": "Hockey Cards", "category_path": "hockey-card-values", "set_path": "1974-topps" }, { "set_id": 1240, "set_name": "1974 Topps Deckle Edge", "category_name": "Baseball Cards", "category_path": "baseball-card-values", "set_path": "1974-topps-deckle-edge" }, { "set_id": 2491, "set_name": "1974 Topps Stamps", "category_name": "Baseball Cards", "category_path": "baseball-card-values", "set_path": "1974-topps-stamps" } ] } } ```
MCPツール psa_price_guide_sets
/psa/price-guide/setFetches one PSA Price Guide set's full grade-by-grade price table: every card in the set with PSA's own formatted price per grade column (the set's own grade columns vary -- a vintage set may carry more/lower grade tiers than a modern one). category_path, set_path and set_id together identify the set; use the matching fields from a psa-price-guide-search result, or category_path from psa-price-guide-categories combined with a set_path/set_id found by browsing PSA's own category page.
レスポンスに関する注記
- `category_path`, `set_path` and `set_id` must all three match exactly — the numeric `set_id` alone does not resolve if either slug is wrong. Use the matching fields from one `psa-price-guide-search` result rather than constructing them independently. - `grades` is the set's own grade-column labels, in PSA's own display order (e.g. `["NM 7","NM-MT 8","MT 9","GEM-MT 10"]`). This varies by set — a vintage set may carry more/lower grade tiers than a modern one. - A card's `prices` map omits any grade with no price for that card, rather than including it with an empty value. - Some rows are PSA's own group-summary entries (e.g. "Commons 1-660") covering a print-run range rather than one specific card. These carry real prices but no `item_id`. - A `category_path`/`set_path`/`set_id` combination PSA cannot resolve returns `404`.
MCPツール psa_price_guide_set
/psa/cardfacts/categoriesPSA CardFacts' full category list -- the discovery endpoint for the category_id parameter used to browse sets. Nine categories: Baseball, Basketball, Boxing, Football, Golf, Hockey, Misc Sports, Multi-Sport, and Non-Sports/TCG.
レスポンスに関する注記
- This is a separate category id space from `psa-price-guide-categories`, `psa-autographfacts-categories`, `psa-ticketfacts-categories`, and `psa-probatfacts-categories` — ids `10` and `16` in particular mean different things in CardFacts than in Price Guide. Do not assume a shared category id means the same category across PSA's different sub-products.

PSAのスクレイピング方法
PSA publishes public certification verification, price-guide data, and several authentication reference families (CardFacts, AutographFacts, ProBatFacts, TicketFacts) on its own site. Crawlora's PSA endpoints return each family's category taxonomy alongside its detail data as normalized JSON -- no account. A pull on 2026-10-27 showed three separate category directories for card facts (9), price guide (16) and autograph facts (19), and that the same sport has different ids in each.
Pass a PSA cert number to /psa/cert-lookup to verify it.
List categories with /psa/price-guide/categories, search card or player queries with /psa/price-guide/search, or search set names with /psa/price-guide/sets. The set search matches names only; pass its returned category_path, set_path, and set_id to /psa/price-guide/set for the full table.
List categories with /psa/cardfacts/categories, sets in a category with /psa/cardfacts/sets, and a set's card checklist with /psa/cardfacts/checklist.
List categories and subjects in a category, then pass a subject to the family's own subject-profile and exemplar-gallery endpoints (e.g. /psa/autographfacts/subject and /psa/autographfacts/gallery).
cardfacts categories returned 9, price-guide categories 16 and autographfacts categories 19. Baseball is id 13 in card facts, 13 in the price guide (Baseball Cards, path baseball-card-values) and id 4 in autograph facts, so never reuse a category id across products.
The set and checklist routes take ids from the category and set routes, and the price-guide set route also needs a category path and set path. Keep the path strings with the ids.
