Batch backtest (many stocks × many strategies) API
Run many stocks × many strategies in one call and get a side-by-side comparison table. Pass `codes` (comma-separated, up to 20) and `strategies` (comma-separated, up to 10; max 60 combinations). Each stock's history is loaded once and shared across every strategy, so a 15-combination batch returns in about a second — far faster than calling `/v1/backtest` 15 times. Returns a row per (stock, strategy) with total return / CAGR / Sharpe / max drawdown / volatility / trade count, plus a `skipped` list for codes without enough history. Same cost model, price-limit and suspension constraints as `/v1/backtest`. Paid tier — Pro (¥99) and above, 20 batches/day (Unlimited ¥199: 100/day).

Rows live in `data`; when upstream returns nothing you get `ok:false` and the call is not counted.
Free endpoints need no key (anonymous 5/min — 250 bars per request, 100k rows per day; solve one PoW challenge for 15/min). Paid tiers: Trial 30 · Standard 120 · Pro 300 · Unlimited 600 per minute; buyout packs are capped by total calls and never expire.

General (applies to every endpoint)
Free endpoints do not: health, challenge, quote, kline, hot, market-overview and changedist work anonymously. Paid endpoints do: send `Authorization: Bearer
No. When the upstream fails or returns nothing you get `ok:false` and the charge for that call is refunded (total_calls / usage_log / ep_log are rolled back together). Only calls that actually returned data count.
Quotes (quote / kline / orderbook / changedist) are real-time or current session; financials, shareholders, dividends and events are within T+1 of upstream disclosure. The `source` field in every response tells you which data channel actually served it.
No. `code` is a single-value parameter — one stock per call. For batches, issue concurrent calls and respect your tier per-minute limit.
