The App Stores Cooolest API

smbcloud-ascapi

smbcloud-ascapi is the app stores coolest API.

Nine crates, split by domain and layered so neither front end can drift from the other:

Crate	What it is
smbcloud-ascapi-core	Shared transport: JWT auth, the HTTP client, JSON:API envelopes, error types
smbcloud-ascapi-play	Google Play (Edits v3): store listings, listing images, track release notes; service-account auth, independent of core
smbcloud-ascapi-appgallery	Huawei AppGallery Connect Publishing API (Android): app info and listings, file and package upload, submit, phased release, release time, GMS flag, package list and status; Service Account auth (PS256 JWT), independent of core
smbcloud-ascapi-aso	App Metadata: apps, app infos, versions, builds, pre-release versions, review submissions, bundle IDs, localizations, screenshots
smbcloud-ascapi-pricing	Pricing: app price schedules, and the per-territory prices joined with their price points and currencies
smbcloud-ascapi-signing	Code signing: certificates and provisioning profiles, plus local RSA key pair and CSR generation
smbcloud-ascapi-reports	Sales reports: account-level sales data, as Apple's gzip-compressed TSV
smbcloud-ascapi-frontend	Operations both surfaces share, so the CLI and the MCP server agree by construction, plus the CLI's xcrun altool upload
smbcloud-ascapi-mcp	The MCP contract and stdio server
smbcloud-ascapi-cli	The asc binary: clap command tree, plus --mcp

aso, play, appgallery, pricing, signing and reports know nothing about each other, and neither knows anything about the front ends. Each adds its calls to smbcloud_ascapi_core::Client as extension traits, since Rust only allows inherent impls in the crate that defines a type:

use smbcloud_ascapi_core::{ApiKey, Client};
use smbcloud_ascapi_aso::prelude::*;      // or pricing::prelude, signing::prelude

MCP Registry name: mcp-name: io.github.smbcloudXYZ/ascapi

Credentials

The CLI signs requests with an App Store Connect API key:

Flag	Environment variable	Notes
--key-id	ASC_API_KEY	The key id. There is no ASC_KEY_ID.
--issuer-id	ASC_ISSUER_ID	The issuer id from App Store Connect.
--private-key-path	ASC_PRIVATE_KEY_PATH	Defaults to ~/.appstoreconnect/private_keys/AuthKey_<key-id>.p8.

With --mcp, credentials are resolved on each tool call, so the server can list its tools before they are configured.

AppGallery credentials

asc appgallery uses an AppGallery Connect Service Account (developer-level, with a publishing role), not the App Store Connect key:

Flag	Environment variable	Notes
--service-account	APPGALLERY_SERVICE_ACCOUNT_JSON_PATH	The *private.json file; or its contents in APPGALLERY_SERVICE_ACCOUNT_JSON.
--client-id	APPGALLERY_CLIENT_ID	Optional client_id header.

asc appgallery app-id xyz.smbcloud.SiGit
asc appgallery listings list <APP> [--lang en-US]          # every field the API returns
asc appgallery listings update <APP> --lang en-US --brief "..." --release-notes-file notes.txt
asc appgallery listings delete <APP> --lang id
asc appgallery info update <APP> --privacy-policy URL [--category ID --category-tag ID]
    [--publish-country CODES] [--developer-website URL] [--device-types JSON] ...
asc appgallery files upload <APP> --type icon --lang en-US icon-216.png
asc appgallery files upload <APP> --type screenshots --orientation portrait --lang en-US 1.png 2.png
asc appgallery files upload <APP> --type package siGit.apk      # chineseMainlandFlag=0 unless --chinese-mainland
asc appgallery packages list <APP>
asc appgallery packages status <APP> <PKG_ID>...
asc appgallery gms <APP> --needs-gms false
asc appgallery submit <APP> [--release-time T] [--remark TEXT] [--phased-start T --phased-end T --phased-percent P --phased-description D]
asc appgallery phased-release <APP> (--to-full | --state SUSPEND|RELEASE | --phased-percent P ...)
asc appgallery release-time <APP> (--immediately | --at T)

<APP> is the numeric app id or the package name. Every write takes --dry-run. Binding an image or video for a language clears that language's text; files upload reads the text first and writes it back if it went missing. MCP has three read-only tools: appgallery_app_info_get, appgallery_package_list and appgallery_package_status.

Not covered: the "download mode" submit and package calls, which need a public package URL and a callback server for Huawei to report to.
