File contents

yax — Yandex 360 CLI

CLI tool for Yandex Disk, Calendar, and Mail via Yandex OAuth API.

Features

Disk: info, list, mkdir, upload, download
Calendar: list calendars, create events (via CalDAV)
Mail: ⚠️ Limited — Yandex has no public HTTP API for mail (IMAP/SMTP only, ports often blocked in cloud)

Prerequisites

Create a Yandex OAuth app at https://oauth.yandex.ru/client/new
- Redirect URI: https://oauth.yandex.ru/verification_code
- Required scopes:
  - cloud_api:disk.app_folder — Disk app folder access
  - cloud_api:disk.info — Disk info
  - calendar:all — Calendar read/write
  - mail:smtp — Mail sending (SMTP only, no HTTP API)
- Note the Client ID and Client Secret

Save config to ~/.openclaw/yax.env:

YAX_CLIENT_ID=your_app_client_id
YAX_CLIENT_SECRET=your_app_secret_if_any

Setup & Auth

scripts/setup.sh        # Create env template
node src/yax.cjs auth   # OAuth flow (opens browser URL, paste code)

Usage

# Disk
node src/yax.cjs disk info
node src/yax.cjs disk list /
node src/yax.cjs disk mkdir /test-folder
node src/yax.cjs disk upload ./local-file.txt /remote-path.txt
node src/yax.cjs disk download /remote-path.txt ./local-file.txt

# Calendar
node src/yax.cjs calendar list
node src/yax.cjs calendar create "Meeting" "2026-02-14" "11:00:00" "12:00:00" "Holiday meeting" "Europe/Moscow"

# Mail (informational only)
node src/yax.cjs mail

Implementation Details

Calendar: Uses raw CalDAV HTTP requests to caldav.yandex.ru. Automatically discovers user login via OAuth info endpoint and calendar paths via PROPFIND. Supports timezone-aware event creation. No external dependencies.
Mail: Yandex does not offer a public REST/HTTP API for mail operations. Only IMAP/SMTP is available, which requires direct TCP connections on ports 993/465 — typically blocked in cloud environments (Railway, etc.). The Yandex 360 Admin API exists for organization accounts but is not suitable for personal use.
