description

CLI & agent skill for a PayPay証券 (PayPay Securities, ペイペイ証券) account: check portfolio, holdings, balance, 投資信託, 米国株, 取引履歴 (transaction history), fees & FX-spread; generate a 復盘/review with realized & unrealized P&L and money-weighted return (XIRR); 持仓结构/exposure (risk), 定投/つみたて recurring-buy plans (plans), per-year tax view (tax), account snapshots & diff (snapshot/diff), multi-account consolidation (-a all), Chinese output (--lang zh); AND place 米国株 orders (buy/sell/cancel). Use when the user wants to view, review, analyze, report, or trade a PayPay証券 / PayPay investment account. Orders dry-run by default; a live order requires an explicit human `--execute` with a typed confirmation + the account TRADE_PASSWORD (the agent never auto-submits). Facts only — never investment advice or buy/sell judgments.

paypay-securities — read-only PayPay証券 client

A small Python CLI that authenticates to the PayPay証券 web frontend and reads account data. There is no official or unofficial API/SDK for PayPay証券, so this talks to the same endpoints the website uses.

Scope

Phase	Status	What
0 — auth	✅ done	/login.json + trusted-device cookie → session token, no SMS
1 — read (証券)	✅ done	balance, portfolio (per-holding), asset/cash history
1b — read (投信)	✅ done	mutual-fund valuation/principal/P&L via JSON API; total aggregation
2 — export/notify	not built	scheduled pull + push to Lark/WeChat/email
3 — trading (証券 米国株)	✅ built	buy/sell/cancel via the web order flow — dry-run by default; live --execute is human-only (typed confirm + TRADE_PASSWORD); per-order + daily-count guards

Account is split across systems (see also the project memory): 証券 (this site, incl. the cash balance in the transaction ledger), 投信 (/investment_trust/ Vue SPA + JSON API, same session), and CFD (cfd.paypay-sec.co.jp, separate login — not integrated). paypay total/assets cover 証券 + 投信 + cash = the app's full grand total; only CFD is out of scope.

Install

npx skills add leeguooooo/paypay-securities --skill paypay-securities      # project-local
npx skills add leeguooooo/paypay-securities --skill paypay-securities -g   # user-global (~/.claude/skills/)

The CLI (the bundled paypay_sec/ package + pyproject.toml) is installed alongside this SKILL.md. Requires uv on PATH.

Setup (credentials)

Put credentials in ~/.paypay-sec/.env (outside the repo / installed skill — this path is searched first, so the CLI works from any directory). Template in .env.example:

• PAYPAY_MEMBER_ID, PAYPAY_PASSWORD
• PAYPAY_COOKIE — the full Cookie header from a logged-in browser. It must contain the ..._SMS_AUTH_STRING trusted-device token, otherwise the server demands an SMS code and login fails.

Never commit credentials or pass them on the command line. (PAYPAY_ENV overrides the path; ./.env / ./spike/.env are also searched for dev checkouts.)

Multiple accounts: each account is a profile. The default account reads ~/.paypay-sec/.env; a named account <name> reads ~/.paypay-sec/<name>.env. Select one with -a <name> (or the PAYPAY_ACCOUNT env var) — e.g. uv run paypay assets -a second. Each account keeps its OWN session + response cache (default → ~/.paypay-sec/, named → ~/.paypay-sec/<name>/) so they never collide. paypay accounts lists the configured profiles.

Commands

Run from this skill's directory: uv run paypay <cmd> (uv resolves deps from the bundled pyproject.toml; the paypay entry point is defined there).

uv run paypay login                 # force a fresh login (refreshes the cached session)
uv run paypay logout                # clear the cached session
uv run paypay balance               # 証券: 評価額合計 / 投資元本 / 含み損益
uv run paypay portfolio             # 証券 holdings: valuation, shares, cost, P&L, account type
uv run paypay history               # 証券 daily asset/cash time series
uv run paypay invtrust              # 投信 (mutual funds): valuation / principal / P&L / 売却申込中
uv run paypay invtrust-history      # 投信 ledger (MARKET_ID=99): 買付/売却/入金/譲渡益税/送金手数料 + moving-avg realized P&L + 現保有(口座別 NISA/特定)
uv run paypay total                 # aggregate 証券 + 投信 invested assets (excludes cash)
uv run paypay assets                # one-shot consolidated holdings + cash + grand total (parallel)
uv run paypay trades [--pages N]    # 証券 transaction ledger (買付/売却/入金/手数料) + running cash balance
uv run paypay fees [--detail]       # cost analysis: explicit fees + measured FX spread (+ optional price spread)
uv run paypay review                # 复盘: 2 blocks — 持仓盈亏(評価損益=App頭条) + 账户盈亏(通算=総資産−純入金); + realized/costs
uv run paypay trades-summary        # per-brand buy/sell/net-invested/net-shares/realized P&L
uv run paypay risk [--accounts]     # 持仓结构 / exposure: weights, concentration, FX/category split (+口座区分 with --accounts; FACTS ONLY)
uv run paypay plans                 # 定投/つみたて: active recurring-buy funds + monthly run-rate (scans FULL history by default; --fast = quick)
uv run paypay tax                   # per-year tax view: 売却 / 譲渡益税 / 分配金 (FULL history by default; --fast = quick; 年間取引報告書 参考, FACTS ONLY)
uv run paypay snapshot save         # save a dated account snapshot (the CLI's own time series)
uv run paypay snapshot list         # list saved snapshots
uv run paypay diff [--days N]       # diff a live read vs the latest (or ~N-days-old) snapshot
uv run paypay calendar              # build 每日涨跌日历 HTML from snapshots (--json = raw schema; --out PATH; -a all = household, the default)
uv run paypay doctor [--online]     # diagnose setup/login readiness (offline by default; --online probes login + 証券/投信 to confirm the session is live)
uv run paypay accounts              
uv run paypay cache-clear           

risk is facts-only. It reports portfolio structure — total, cash %, largest position %, top-1/3/5 concentration, 種類/口座 splits, and two distinct currency/region measures: 米国 計価(証券, USD-quoted) vs 米国株 底層暴露 (US-underlying, which also counts JPY-priced S&P500/NASDAQ etc. 投信). It gives no risk verdict and no buy/sell advice, same boundary as every other command.

snapshot / diff give the account its own long-term series: snapshot save writes <state_dir>/snapshots/<ts>.json (assets, cash, holdings, realized, deposits); diff compares a live read against the latest snapshot (or --days N ago) so you get "this week's change" — asset/holdings/deposit/realized deltas. Automate it: bin/snapshot-cron.sh install schedules a daily (07:30 local, trading days) read-only snapshot of every profile + a calendar rebuild + a Monday diff --days 7, logged to ~/.paypay-sec/snapshot-cron.log (uninstall / status too).

calendar reads only the saved snapshots (no creds/network) and builds a single self-contained, offline HTML — the 每日涨跌日历: month + year (GitHub-style heatmap) views, 红涨/绿跌, per-account toggle + 合计. Each day's value is the snapshot-to-snapshot change in 総資産 minus that day's net cash flow (so deposits aren't counted as profit; full-quality, includes 投信). Needs ≥2 snapshots on different days per account. Default / -a all = household (all profiles); -a <name> = one. Labels come from PAYPAY_LABEL in each .env (else the profile name). The template (paypay_sec/calendar_template.html) is data-driven: the cron regex-swaps the JSON between /* DATA_START */ … /* DATA_END */. --json emits the raw schema.

Any command takes -a <name> to target a non-default account, and --format table|lark|json. --format lark emits Feishu/Lark-friendly bullets (bold numbers, +¥/-¥, no wide tables) — use it for review / trades-summary / risk / diff when posting to Lark.

--lang ja|zh localizes the table/lark labels (zh = 中文: 総資産→总资产, 評価損益→持仓盈亏, 実現→已实现, …); JSON output keys stay English. --all pages the full ledger history (until NEXT_FLG=false) for complete realized P&L instead of the default page cap. Reports also stamp 查询时间 (as_of) + per-source freshness (live/cache/stale) and loudly flag any feed that failed — never silently ¥0.

JSON is versioned: every --json dict payload carries schema_version (currently "1.0") so cron jobs / dashboards / the daily snapshot can parse it stably.

-a all consolidates across every configured account profile (total / assets / risk / plans / tax): combined household view (same fund summed) + per-account totals — e.g. risk -a all shows whole-household concentration & US-underlying exposure. review also reports a money-weighted return (XIRR, 資金加重収益率) — the proper annualized performance when 定投/deposits are ongoing (use --all for the full deposit history).

Scope of the read commands: data display only. The commands above just show your account's data (or factual calculations on it — totals, realized P&L by average-cost basis, cost aggregation). They give NO judgments, NO risk/position rules, NO buy/sell advice. Order placement is a separate, explicit flow ↓ — and it too gives no advice: it places exactly the order you specify, nothing more.

Ordering (下单 — 米国株 buy/sell/cancel)

Trading is OFF by default. buy/sell/orders/cancel refuse to run unless the human sets PAYPAY_TRADING_ENABLED=1 (in ~/.paypay-sec/.env or the shell). A read-only / 复盘 invocation can't place an order even by accident — this capability gate sits on top of the dry-run + confirm + TRADE_PASSWORD wall below.

PayPay証券 has no order API; this drives the same un-pinned web order endpoints the site uses (/trade/brand/ajax_*_popup → ajax_*_complete). The agent never auto-submits a live order. Every order is a dry-run (見積/preview only) unless a human adds --execute, and --execute then requires (1) typing an exact confirmation phrase and (2) entering the account TRADE_PASSWORD (取引パスワード) at an interactive getpass prompt. The agent does not know, store, or handle that password — only the live confirm/preview ever runs unattended.

# DRY-RUN (default) — runs the real 見積/confirm, prints the quote, places NOTHING
uv run paypay buy  TSLA --amount 10000        # 金額指定: ¥10,000 of TSLA, at the quote
uv run paypay buy  TSLA --qty 1               # 株数指定: 1 share
uv run paypay sell TSLA --qty 0.5             # sell 0.5 share
uv run paypay buy  QQQ  --amount 50000 --account-type 3   # into 成長投資枠 NISA

# LIVE — human only. Prompts for the confirmation phrase, THEN the TRADE_PASSWORD.
uv run paypay buy  TSLA --amount 10000 --execute

uv run paypay orders                          # list 未約定/予約注文 (pending orders)
uv run paypay cancel <ORDER_ID>               # cancel a pending order

• --amount <yen> (金額指定) or --qty <shares> (株数指定) — exactly one.
• --limit <price> is optional — PayPay 米国株 fill at the prevailing quote; give --limit only for a 指値, or --market-order to force 成行.
• --account-type — 2=特定 (taxable/cash, default) · 3=成長投資枠NISA · 4=つみたて.
• Guards (in guards.py / TradeConfig): allow_markets (米国株 only for now), max_order_jpy per order, and a daily order-count cap. A blocked order prints ⛔ order blocked by guards: … and never reaches the network confirm.
• Every order attempt is appended to an audit log (audit.py) with a daily count.
• Funding model: the account is funded by cash balance (you top it up); orders are placed against that cash. Bank-card buying is mobile-app/passkey-only and out of scope.

Run from anywhere (no cd): symlink the bundled launcher onto your PATH — ln -s <skill-dir>/bin/paypay ~/.local/bin/paypay (skill-dir varies by runner: ~/.claude/skills, ~/.hermes/skills, ~/.agents/skills, …) — then paypay review --format lark works in any directory (the launcher resolves the symlink + skill dir and runs uv run there).

total / assets scope: 証券 (株+ETF) + 投信 holdings + the account cash balance, giving the full grand total that matches the app's 保有資産 figure. The cash comes from the transaction ledger's running CASH_BALANCE (/trade/history/ajax_settlement.json), NOT from PayPayマネー — the cash lives on the securities site after all. Only CFD (cfd.paypay-sec.co.jp, separate login) is excluded.

Response cache (anti-throttle): every GET/POST response is cached to ~/.paypay-sec/cache/ with a TTL (default 120s, env PAYPAY_CACHE_TTL). Repeated or overlapping commands (and the total/assets/trades trio, which share the settlement ledger) reuse cached data instead of re-hitting the API — important because the ajax_settlement endpoint throttles (returns empty) when hammered. --no-cache forces fresh fetches; paypay cache-clear empties it.

Session reuse: after the first login the session cookies + token are cached to ~/.paypay-sec/session.json (mode 0600) and reused, so /login.json is hit only on a cold start or when the session has expired (a fetch bouncing to /login/ triggers exactly one automatic re-login). This keeps load off the login endpoint instead of authenticating on every command.

Flags (place AFTER the subcommand, e.g. uv run paypay portfolio -m usa -a second --json):

• -m, --market <usa|japan> — market segment. Aliases: jp→japan, us→usa, 米国株, 日本株. Default usa.
• -a, --account <name> — account profile (default reads ~/.paypay-sec/.env).
• --json — machine-readable output.
• --no-cache — bypass the response cache.

Architecture (for maintenance)

• config.py — credential loading from .env/env (never logged).
• client.py — PayPayClient: login() + get_page(); market-slug aliases; the web order methods order_confirm() / order_submit() / open_orders() / order_cancel() (FuelPHP CSRF from the fuel_csrf_token cookie; ticker→BRAND_ID resolution; single-use ORDER_CONFIRM_NO tokens).
• orders.py — order model (OrderRequest) + the build→guard→confirm→[confirm phrase]→submit pipeline (dry_run() / place()); injected confirm/submit callables so the live submit is never reached except via the human path.
• guards.py — TradeConfig + check_guards(): allow-listed market, per-order yen cap, daily order-count cap (pre- and post-confirm checks).
• audit.py — append-only order log + daily order count.
• parsers.py — all site-specific selectors live here. Data sources:
  • account header → div.mypage_assets_data / .mypage_invest / .mypage_gain
  • holdings → table.d_table on /trade/portfolio/brands/<market>
  • history → var ticks/cashData/acuisitionData JS arrays (values in 万円)
  • 投信 valuation → parse_invtrust() over the POST /v2/invest/brand/pc_invest_top JSON (NOT HTML — the 投信 page is a Vue SPA; the JSON API needs the FormData fields APP_VERSION/UUID/DEVICE_TOKEN/OS/APP_ID, empty body hangs the server)
  • 投信 ledger → parse_invtrust_transactions() over GET /v0/history/settlements.json?MARKET_ID=99&PAGE_NUM=<n>&OS=pc — a SEPARATE market view from the 証券 ajax ledger (the SPA's "取引の履歴" tab). Holds 投信 買付/売却/入金/譲渡益税(type 8)/送金手数料(type 54), with 口座区分 in ACCOUNT_TYPE (1 一般 / 2 特定 / 3 NISA成長 / 4 NISAつみたて). PAGE_NUM here is a RECORD OFFSET (n..n+19), same gotcha as the 証券 ajax — step by 20 + de-dup by SEQ_NO (paging by 1 without de-dup inflates totals ~10×). MINI_CLIENT_SEQ_NO is optional. The 入金/送金手数料 rows are account-wide (identical to the 証券 ledger); only 買付/売却/譲渡益税 are 投信-specific. review folds its realized P&L + 譲渡益税 + 送金手数料 into the full-account 総収益 so the 証券-only residual no longer hides 投信 trading. The endpoint throttles (empty) when hammered.

Dev-only, NOT shipped: repo-root tests/ (real-fixture tests; gitignored as it holds account HTML/JSON). Run: uv run --project skills/paypay-sec python tests/test_parsers.py. Committable synthetic regression tests for the 投信 ledger + moving-average: skills/paypay-securities/selftest.py — uv run --project skills/paypay-securities python skills/paypay-securities/selftest.py.

Fragility: the 証券 pages are server-side-rendered HTML, so a frontend redesign breaks parsing — fix only parsers.py (all selectors live there).

Safety

The read commands are read-only. The order commands place trades, behind a human-in-the-loop wall:

• Trading is disabled by default. buy/sell/orders/cancel refuse to run unless PAYPAY_TRADING_ENABLED=1 is set — a read-only/复盘 session has no order capability at all.
• Dry-run is the default. Even when enabled, a bare buy/sell only runs the 見積/preview; it places nothing. A live order requires an explicit --execute.
• --execute is human-only. It demands a typed confirmation phrase and the account TRADE_PASSWORD at an interactive prompt. The agent never enters that password and is not built to run a live submit unattended.
• Guards + audit. Per-order yen cap, allow-listed market, daily order-count cap; every attempt is logged. Confirm tokens (ORDER_CONFIRM_NO) are single-use and writes are never auto-retried.
• No advice. The skill places exactly the order you specify and never offers buy/sell/position judgments.

Automated access to a brokerage may conflict with PayPay証券's terms of service — use on your own account at your own risk. The order confirm/submit response field names + the open-orders column mapping are finalized against a live capture when the US market is open (closed → buyable=0 → confirm returns STATUS=false), so run a dry-run buy at market open to validate before the first live --execute.
