25 tools

• get_account

  The account: its apps with Apptail ids, its plan and the limits that can refuse a write, App Store Connect health per app, how fresh the first-party data is, and the storefronts it focuses on. Call this first whenever the request is about "my app" or "my keywords" — every other…

• explain_period

  Return an account or owned-app summary for a requested period: available measured App Store Connect performance, storefront changes, tracked keyword movements, recorded signals, review volume and the last sent digest. Returns comparison data, coverage and caveats identifying…

• get_performance

  Read measured App Store Connect impressions, store views, downloads, sales and proceeds for apps connected to the authenticated account. Supports an owned app or portfolio, documented time windows, period comparisons and breakdowns by storefront or traffic source. Returns the…

• get_signals

  What actually happened, from the record the product keeps: rank moves on tracked terms, chart entries, review spikes, competitor releases and price changes, plus — for the user's own apps only — week-over-week traffic and conversion shifts, download collapses, new reviews and…

• search_apps

  Search for iOS apps by name, bundle ID, or App Store URL. Supports all languages including Cyrillic, Chinese, etc. If the app is not in our database, it will be fetched from the App Store, persisted as a shared public app record, and queued for enrichment. This does not add the…

• get_app

  Everything AppTail holds about one app, at the depth you ask for. The base answer is the store listing **in one storefront** — the localised title and subtitle a shopper in `country` actually reads, the price and its currency, version, category, release dates, the publisher's…

• get_keywords

  The account's tracked keywords for an app — or across the whole portfolio — over any window: where each term ranked at the start and end, how far it moved, how many days it held and how many days it was measured, and optionally its day-by-day history, the same terms measured for…

• get_keyword_serp

  The App Store search results for one term in one storefront, on one day: who ranked, in what order, with their names, subtitles and ratings. This is how you find out WHO took the places an app lost — a rank that fell is a fact, and the results page on the day it fell is the…

• discover_keywords

  Terms an app could be tracking but is not, merged from every source and each labelled with where it came from: what tracked competitors rank for, what the store's similar apps rank for, what those competitors put in their own titles and subtitles, what the store's own mining…

• add_keywords

  Start tracking search terms for one of your apps, in one storefront. Send terms, or `keyword_ids` for suggestions returned by discover_keywords — a suggestion MUST be added by id, because re-resolving its term can land on a different keyword row. Counts against the plan's…

• remove_keywords

  Remove tracked keywords from an app. Frees the slots against the plan limit; position history is kept, so re-adding a term later does not start from nothing.

• tag_keywords

  Put tracked keywords under a tag, in bulk — or clear their tag — and/or say whether they are brand terms for Search Visibility. The tag is named, not looked up: a name that does not exist yet is created. A keyword carries at most one tag, so assigning replaces whatever it had…

• get_competitors

  List tracked competitor apps for one of your apps, with how many more the plan allows — and `suggested`: up to ten rivals the account does not track yet, ranked by how many of the app's own search terms they sit in the top ten for. Works on an app with no keywords: its listing…

• get_landscape

  Who the App Store shows beside one of your apps for the terms it competes on, in one storefront: every app in the niche with how many of your terms it ranks for and owns the top 10 for, its ratings, its review flow and its size, plus which apps arrived or fell out this window…

• add_competitors

  Track one or more rival apps against one of YOUR apps. Each competitor can be given as an Apptail app_id, an App Store URL, or just a name — names and URLs are resolved and imported the way search_apps does, so you do NOT need to look up an app_id first. Returns one outcome per…

• remove_competitors

  Remove one or more competitor tracking relationships for an app owned by the authenticated account. Accepts AppTail app ids, App Store URLs or names. Name and URL resolution can query the public App Store and import shared app records. Removes the selected pairing only; public…

• add_app

  Add an app to the account as one of the user's own. Takes an Apptail app_id, an App Store URL, or a name — resolved and imported the way search_apps does. Tracking starts immediately (rankings, reviews, competitors); measured downloads and proceeds still require connecting App…

• get_market

  Read iOS App Store niche data by saved market_id or by query and countries. Returns storefront competition, search visibility, app membership and optional corpus or movement data. Phrase research can create shared keyword records and persist crawled search observations; it does…

• list_markets

  List markets saved by the authenticated account, including market ids, storefronts, competition ranges, app counts and observed changes for the requested period. Reads saved account configuration and market observations without creating, updating or deleting markets. Returned…

• save_market

  Create or update a saved market in the authenticated account from a query, countries and optional per-storefront seed terms. An existing name updates that market, adding storefronts or replacing seed configuration and rebuilding requested storefronts. Persists account…

• edit_market_corpus

  Add terms to one storefront's corpus, or take terms out of it. Add for a term the corpus SHOULD hold and does not — a rival's brand, a phrase Apple has never measured the popularity of, the term a thin storefront is really about; a pinned term is kept through every rebuild and…

• remove_market

  Delete a saved market, or just one of its storefronts. Pass `store` to drop a single storefront and leave the rest of the market with its corpora and its build clocks untouched; omit it to delete the whole market. Deleting frees a slot on the account's plan. The terms themselves…

• get_top_charts

  Get top app charts (free, paid, or grossing) for a store, country, and category.

• get_reviews

  Reviews for any app over a window, filtered by storefront, star rating, text, or whether the developer has replied — plus the shape of the period: how many arrived per bucket, what they averaged, and where the app's pooled store rating stood while they did. Reviews exist for…

• reply_to_reviews

  Create, update or remove public App Store review responses for apps owned by the authenticated account, using its connected App Store Connect API key. Requires write authorisation and eligible review ids. Submitted text is sent verbatim under the developer's name. Obtain…
