エンドポイントカタログ
/chromewebstore/searchReturns Chrome Web Store search result cards for a keyword, each with id, name, rating, user count, publisher and detail URL. Defaults: `num=30`, `country=us`, `lang=en`.
レスポンスに関する注記
- Each result card carries `id`, `name`, `icon`, `summary`, `rating`, `rating_count`, `users`, `publisher`, `category`, and a detail `url`. - An empty `results` array means the query genuinely returned no items — it does not mean a specific item is missing. To confirm an item's presence, look it up directly with `chromewebstore_item`. - A blocked or shape-changed upstream response is returned as a typed upstream error (HTTP 503), never as `200` with an empty array. Example response: ```json { "code": 200, "msg": "OK", "data": { "query": "vpn", "count": 1, "results": [ { "id": "majdfhpaihoncoakbjgbdhglocklcgno", "name": "Free VPN for Chrome - VPN Proxy VeePN", "rating": 4.5, "rating_count": 50285, "publisher": "veepn.com", "url": "https://chromewebstore.google.com/detail/majdfhpaihoncoakbjgbdhglocklcgno" } ] } } ```
MCPツール chromewebstore_search
/chromewebstore/itemReturns normalized detail for a Chrome Web Store extension or theme, including name, rating, rating count, user count, version, last-updated date, size, supported languages, developer, category, screenshots, and privacy links. Defaults: `country=us`, `lang=en`.
レスポンスに関する注記
- Fields come from the store's server-rendered item detail page: name, summary, full description, rating and rating count, user count, version, last-updated date, size, supported languages, developer, category, screenshots, and privacy links. - A removed or unknown item id returns a typed not-found error (HTTP 404). - A blocked or shape-changed upstream response is returned as a typed upstream error (HTTP 503), never as a partial success. Example response: ```json { "code": 200, "msg": "OK", "data": { "id": "cjpalhdlnbpafiamejdnhcphjbkeiagm", "name": "uBlock Origin", "rating": 4.7, "rating_count": 35457, "users": 13000000, "version": "1.72.0", "updated": "2026-06-29", "size": "4.39MiB", "category": "make_chrome_yours/privacy", "developer": "Raymond Hill (gorhill)", "url": "https://chromewebstore.google.com/detail/cjpalhdlnbpafiamejdnhcphjbkeiagm" } } ```
MCPツール chromewebstore_item
/chromewebstore/reviewsReturns the reviews the store renders on an item's reviews page, each with author, star rating, text, posted/edited dates and reviewed version. Defaults: `num=20`, `country=us`, `lang=en`.
レスポンスに関する注記
- `total` is the item's overall review count; `count` is how many were returned. - Each review carries `id`, `author`, `avatar`, `rating` (1–5 stars), `text`, `helpful` (how many found it helpful), `posted`/`edited` dates, reviewed `version`, and `language`. - Reviews are paginated up to `num`, ordered by the store's `recent` (newest) or `helpful` (most relevant) sort. - A removed or unknown item id returns an empty result. A blocked or shape-changed upstream response is returned as a typed upstream error (HTTP 503). Example response: ```json { "code": 200, "msg": "OK", "data": { "id": "cjpalhdlnbpafiamejdnhcphjbkeiagm", "total": 10482, "count": 1, "reviews": [ { "id": "c05ba4d6-b816-49c4-80f6-ab1fcfdb1454", "author": "delta", "rating": 5, "text": "so good, chrome wants it gone", "posted": "2026-07-06", "version": "1.72.0", "language": "en" } ] } } ```
MCPツール chromewebstore_reviews
/chromewebstore/permissionsReturns the permissions a Chrome Web Store extension declares in its manifest: `permissions`, `optional_permissions`, `host_permissions`, `optional_host_permissions`, plus `manifest_version` and `min_browser_version`. Useful for security and supply-chain review. Defaults: `country=us`, `lang=en`.
レスポンスに関する注記
- `permissions`, `optional_permissions`, `host_permissions`, and `optional_host_permissions` come from the extension's manifest, plus `manifest_version` and `min_browser_version`. Useful for security and supply-chain review. - An unknown item id returns a typed not-found error (HTTP 404). A blocked or shape-changed upstream response is returned as a typed upstream error (HTTP 503). Example response: ```json { "code": 200, "msg": "OK", "data": { "id": "cjpalhdlnbpafiamejdnhcphjbkeiagm", "name": "uBlock Origin", "manifest_version": 2, "min_browser_version": "93.0", "permissions": ["alarms", "contextMenus", "storage", "tabs", "webNavigation", "webRequest", "webRequestBlocking", "<all_urls>"], "url": "https://chromewebstore.google.com/detail/cjpalhdlnbpafiamejdnhcphjbkeiagm" } } ```
MCPツール chromewebstore_permissions
/chromewebstore/privacyReturns an extension's privacy disclosures as the store renders them: the developer's data-use statement, whether it collects data, the standard data-handling declarations, and the privacy-policy link. Defaults: `country=us`, `lang=en`.
レスポンスに関する注記
- `disclosure` is the developer's data-use statement; `collects_data` reflects whether it declares collecting or using data; `data_collected` lists the data categories it declares handling (empty when it collects nothing); `declarations` is the list of standard data-handling declarations the store shows; `privacy_policy` is the developer's privacy-policy link. - An unknown item id returns a typed not-found error (HTTP 404). A blocked or shape-changed upstream response is returned as a typed upstream error (HTTP 503). Example response (a data-collecting extension): ```json { "code": 200, "msg": "OK", "data": { "id": "kbfnbcaeplbcioakkpcpgfkobkghlhen", "name": "Grammarly: AI Writing Assistant", "collects_data": true, "data_collected": [ "Personally identifiable information", "Personal communications", "Location", "User activity", "Website content" ], "disclosure": "Grammarly … has disclosed the following information regarding the collection and usage of your data.", "declarations": [ "Not being sold to third parties, outside of the approved use cases", "Not being used or transferred for purposes that are unrelated to the item's core functionality", "Not being used or transferred to determine creditworthiness or for lending purposes" ], "privacy_policy": "https://www.grammarly.com/privacy-policy", "url": "https://chromewebstore.google.com/detail/kbfnbcaeplbcioakkpcpgfkobkghlhen" } } ``` An extension that collects nothing returns `collects_data: false` and an empty `data_collected`, with a "will not collect or use your data" disclosure.
MCPツール chromewebstore_privacy
/chromewebstore/similarReturns the related-items shelf the store renders on an item's detail page. Defaults: `country=us`, `lang=en`.
レスポンスに関する注記
- Related cards use the same shape as search results and never include the item itself. - A removed or unknown item id returns a typed not-found error (HTTP 404). - A blocked or shape-changed upstream response is returned as a typed upstream error (HTTP 503). Example response: ```json { "code": 200, "msg": "OK", "data": { "id": "cjpalhdlnbpafiamejdnhcphjbkeiagm", "count": 1, "results": [ { "id": "ddkjiahejlhfcafbddmgiahcphecmpfh", "name": "uBlock Origin Lite", "rating": 4.5, "rating_count": 3239, "url": "https://chromewebstore.google.com/detail/ddkjiahejlhfcafbddmgiahcphecmpfh" } ] } } ```
MCPツール chromewebstore_similar
/chromewebstore/suggestReturns item-name suggestions for a search prefix, drawn from the top store-search results. Defaults: `num=8`, `country=us`, `lang=en`.
レスポンスに関する注記
- The store exposes no server-rendered typeahead source, so suggestions are the distinct names of the top store-search results for the prefix. - A blocked or shape-changed upstream response is returned as a typed upstream error (HTTP 503). Example response: ```json { "code": 200, "msg": "OK", "data": [ { "term": "AdBlock — block ads across the web" }, { "term": "Adblock Plus - free ad blocker" } ] } ```

/chromewebstore/categoriesReturns the reference taxonomy for the list endpoints: extension category groups and their subcategory slugs, the top-chart identifiers, and known curated collection slugs.
レスポンスに関する注記
- `categories` lists the extension category groups and their subcategory slugs (pass a subcategory slug to `/chromewebstore/category`). - `charts` lists the top-chart identifiers accepted by `/chromewebstore/charts`: `trending`, `popular`, `notable`. - `collections` lists known curated collection slugs accepted by `/chromewebstore/collection`. Example response: ```json { "code": 200, "msg": "OK", "data": { "categories": [ { "group": "productivity", "subcategories": [ "productivity/communication", "productivity/developer", "productivity/education", "productivity/tools", "productivity/workflow" ] } ], "charts": ["trending", "popular", "notable"], "collections": ["editors_picks_extensions", "dark_mode", "ai_productivity"] } } ```
MCPツール chromewebstore_categories

/chromewebstore/developerReturns a Chrome Web Store publisher (developer) by publisher id, including the disclosed trader details — legal name, email, phone, address, website, and D-U-N-S number — plus the publisher's listed items ("More from ..."). Trader fields are only present for publishers that identify as EU traders. Defaults: `num=50`, `country=us`, `lang=en`.
レスポンスに関する注記
- `name`, `legal_name`, `email`, `phone`, `address`, `website`, and `duns` (D-U-N-S number) come from the publisher's disclosed trader details. The trader fields are only present for publishers that identify as EU traders (`is_trader: true`); consumer/individual publishers omit them. - `website` is derived from the domain the store attaches to the publisher's items. - `items` is the publisher's listing ("More from ..."), using the same card shape as search results. - An unknown publisher id returns a typed not-found error (HTTP 404). A blocked or shape-changed upstream response is returned as a typed upstream error (HTTP 503). Example response: ```json { "code": 200, "msg": "OK", "data": { "id": "u63f06aecfdc45d32c13ccc24f56c3d2d", "name": "Adguard Software Limited", "legal_name": "Adguard Software Ltd", "email": "support@adguard.com", "phone": "+35780077147", "address": "Andrea Zakou, Limassol Centre C, office 34, Limassol 3095, CY", "website": "https://adguard.com", "duns": "534532547", "is_trader": true, "url": "https://chromewebstore.google.com/publisher/u63f06aecfdc45d32c13ccc24f56c3d2d", "count": 1, "items": [ { "id": "bgnkhhnnamicmpeenaelnjfhikgbkllg", "name": "AdGuard AdBlocker", "rating": 4.66, "rating_count": 68233, "publisher": "adguard.com", "url": "https://chromewebstore.google.com/detail/bgnkhhnnamicmpeenaelnjfhikgbkllg" } ] } } ```

Chrome Web Storeのスクレイピング方法
Google publishes no public API for reading the Chrome Web Store catalog, so extension data has to come off the store's own pages. Crawlora's 12 Chrome Web Store endpoints return search, listing, review, permission, privacy, chart, category, and publisher data as normalized JSON.
Search by keyword term, use the suggest endpoint for query completions, or browse a category, a curated collection, or a top chart.
The item endpoint takes the extension id; search cards already carry id, name, rating, user count, publisher, and detail URL.
Separate endpoints return an extension's declared permissions and its privacy disclosures — which is what makes extension-risk analysis possible without installing anything.
Every endpoint takes country and lang, so you can compare how a listing, chart, or category ranks across storefronts.
FAQ
Not for reading the public catalog. Google provides a Chrome Web Store Publisher API for managing items you already own, but nothing that exposes search, reviews, charts, permissions, or categories. Crawlora's endpoints read the public store pages and return that catalog as JSON.
The charts endpoint takes a chart of trending, popular, or notable, and accepts country and lang so you can pull a storefront-specific ranking.
Yes. The permissions endpoint returns an extension's declared permissions and the privacy endpoint returns its privacy disclosures, both keyed by extension id — enough to flag over-permissioned or data-collecting extensions across a whole category.
The reviews endpoint takes the extension id and a sort of recent or helpful, with num controlling how many come back.
