QianWen Usage

Query QianWen usage, free tier quota, Token Plan status, and pay-as-you-go billing.

Prerequisites

- QianWen CLI must be installed. Verify with:

qianwen version

If not installed, run:

npm install -g @qianwenai/qianwen-cli

Node.js >= 18 required.

- Authentication: No configuration needed on first use. The CLI handles non-TTY detection and safe login automatically (see Authentication Flow below).

Environment Variables

| Variable | Description | |---------------------------|----------------------------------------------------------------------------------------------| | QIANWEN_KEYRING | Set to plaintext, no, 0, false, or off to opt out of OS keychain credential storage. | | QIANWEN_CREDENTIALS_DIR | Override file-based credential directory (default: ~/.qianwen/credentials). |

Authentication Flow (for Agents)

The CLI auto-detects non-TTY environments and degrades safely — no wrapper script needed.

TL;DR — 3-step auth path

1. qianwen auth status --format json → authenticated: true → skip to commands 2. qianwen auth login --init-only --format json → extract verification_url → open in browser 3. qianwen auth login --complete --format json → poll until success event

Quick check: already logged in?

qianwen auth status --format json

If authenticated: true and token is not expired, skip login entirely.

Recommended: Two-phase login

Works in all environments (desktop, headless, remote container).

Step 1 — Initialize login (non-blocking):

qianwen auth login --init-only --format json

Exits immediately. Parse the stdout JSON events array:

• already_authenticated → user is logged in, skip to commands
• device_code → extract verification_url and present it to the user

  On desktop environments with a browser, open the URL for the user:

open "$VERIFICATION_URL"          # macOS
xdg-open "$VERIFICATION_URL"      # Linux
start "" "$VERIFICATION_URL"      # Windows

Step 2 — IMMEDIATELY start polling (do NOT wait for user confirmation):

qianwen auth login --complete --format json

Parse the stdout JSON events array:

• success → login complete, proceed to commands
• expired → device code expired, go back to Step 1
• error → report failure

  TTY environments (interactive terminal)

  If the agent is running in a TTY (e.g., user's terminal), simply run:

qianwen auth login

The CLI will automatically open the browser and poll until authorization completes.

JSON event structure

Both --init-only and --complete output a single JSON document:

{
  "events": [
    {"event": "device_code", "verification_url": "...", "expires_in": 300},
    {"event": "success", "authenticated": true, "user": {"aliyunId": "..."}}
  ]
}

Event types: already_authenticated, device_code, success, expired, error, pending.

NEVER:

- ❌ Ask the user "Have you completed authorization?" before running --complete

• ❌ Wait for user confirmation before polling — run --complete immediately after presenting the URL
• ❌ Re-run --init-only without completing (this creates a new device code and invalidates the previous one)

  Usage

  All commands support --format json for structured, machine-parseable output (recommended default), and --format text for clean plaintext output.

  For agent use, always prefer --format json and parse the JSON response. Only fall back to --format text when the user explicitly requests human-readable plaintext.

  Never parse table format programmatically — it contains ANSI codes and Unicode borders.

  Auth Commands

  qianwen auth status — Check current authentication state

  qianwen auth status --format json

qianwen auth logout — Revoke session server-side and clear local credentials

qianwen auth logout

Breakdown Parameters: How to Think About Them

Three independent dimensions — combine them freely:

--model (required) + date range + granularity

Model scope:

• --model — single model (e.g. qwen3.5-plus); required for breakdown

  Date range — three patterns, pick by how the user described the period:

  | Pattern | When to use | How it works |

|---|---|---| | --period YYYY-MM | User names a specific month ("March", "last April") | Exact calendar month, start to end | | --period | User describes a relative period | last-month = previous full month; month = this month so far; quarter = this calendar quarter so far | | --days N | User says "last N days" | Rolling window backwards from today, crosses month boundaries naturally | | --from YYYY-MM-DD --to YYYY-MM-DD | User gives explicit dates or a named quarter/range | Full control, use when other patterns don't fit |

Granularity — determines the grouping of results, not the range:

- day (default) — one row per day; good for spotting usage spikes

• month — one row per calendar month; good for multi-month trends
• quarter — one row per quarter; good for Q-over-Q comparison

  Classic examples:

Single model, single month, daily detail
qianwen usage breakdown --model qwen3.5-plus --period 2026-03
Single model, last 3 months, monthly summary
qianwen usage breakdown --model qwen3.5-plus --days 90 --granularity month
Single model, specific quarter, quarterly rollup
qianwen usage breakdown --model qwen3.5-plus --from 2026-01-01 --to 2026-03-31 --granularity quarter
Single model, this month, daily breakdown
qianwen usage breakdown --model qwen3.6-plus --period month

Output and Agent Display Rules

CLI commands return JSON by default in agent/pipe environments (auto format: TTY → table, pipe → json). JSON is the primary output mode for agents — always pass --format json explicitly, parse the structured response, then present a human-readable summary to the user.

JSON output example (--format json)

qianwen usage summary --period month --format json

Returns structured JSON with three sections:

{
  "period": { "from": "2026-04-01", "to": "2026-04-24" },
  "free_tier": [
    { "model_id": "qwen3.6-plus", "quota": { "remaining": 850000, "total": 1000000, "unit": "tokens", "used_pct": 15 } }
  ],
  "coding_plan": {
    "subscribed": true,
    "plan": "PRO",
    "windows": {
      "per_5h": { "remaining": 4800, "total": 6000, "used_pct": 20 },
      "weekly": { "remaining": 38200, "total": 45000, "used_pct": 15 },
      "monthly": { "remaining": 82500, "total": 90000, "used_pct": 8 }
    }
  },
  "pay_as_you_go": {
    "models": [
      { "model_id": "qwen3.6-plus", "usage": { "tokens_total": 480000 }, "cost": 0.38, "currency": "USD" },
      { "model_id": "qwen-plus", "usage": { "tokens_total": 460000 }, "cost": 0.13, "currency": "USD" }
    ],
    "total": { "cost": 0.51, "currency": "USD" }
  }
}

⚠️ CRITICAL: How to present output to the user

When using --format json (recommended for agents):

1. Parse the JSON and extract the relevant data for the user's question 2. Present a human-readable summary — do not dump raw JSON to the user 3. Add analysis AFTER the summary — clearly separated with ---

When using --format text:

1. Display CLI output EXACTLY AS-IS — no modification, no reformatting 2. Preserve all formatting — alignment, spacing, progress bars, separators 3. Add analysis AFTER output only — clearly separated with ---

NEVER:

• ❌ Dump raw JSON to the user without interpretation
• ❌ Reformat or summarize text/table output
• ❌ Add prefixes like "Here's your usage:"
• ❌ Convert text/table output to bullet points

  ✅ CORRECT (JSON mode):

Your QianWen usage for April:
Free Tier: qwen3.6-plus has 85% remaining (850K / 1M tokens), wan2.6-t2i has 76% remaining (38 / 50 images).
Token Plan (PRO): 8% used this month (82.5K / 90K requests).
Pay-as-you-go: $0.51 total — qwen3.6-plus $0.38, qwen-plus $0.13.
💡 Analysis: Your qwen3.6-plus free tier is 85% remaining...

✅ CORRECT (Text mode):

[CLI text output - exactly as-is]
💡 Analysis: Your qwen3.6-plus free tier is 85% remaining...

❌ WRONG:

Here's your usage:
qwen3.6-plus: 850K tokens remaining (85% left)

Exit Codes

| Code | Meaning | |------|----------------------| | 0 | Success | | 1 | General/usage error | | 2 | Authentication error | | 3 | Network error | | 4 | Configuration error | | 130 | Interrupted |

CLI Update Check

When the user explicitly asks to check for cli updates (e.g. "check for cli updates", "check cli version", "is there a new version cli"):

1. Run: qianwen version --check 2. Report the result.

The QianWen CLI handles update notifications natively; no additional stderr signal handling is required in this skill.

Implementation Notes

- Pay-as-you-go: API returns total usage only (no input/output split)

• Token Plan: Aggregate request counts at plan level (no per-model breakdown)
• logout: Revokes server-side session and clears local credentials (keychain + file). Server-side call is best-effort — local logout always succeeds.
• Authentication: Uses OAuth 2.0 Device Authorization Grant with PKCE. Credentials stored in OS keychain when available, with encrypted file fallback.
• breakdown --model is required: Unlike the previous Python implementation, the CLI requires --model for breakdown. To query all models' usage, use qianwen usage summary instead.
