Quant backtest (single-stock live / portfolio precomputed) API
Run a built-in strategy over history and get return / risk metrics (optionally the equity curve). Two modes: `mode=single` (default) backtests one stock in real time — pass `code` + `strategy`; `mode=portfolio` looks up a precomputed multi-stock result — pass `strategy`. Costs are included: commission (0.03%, min ¥5), stamp duty (0.05%, sell side), transfer fee (Shanghai) and slippage (0.1%). Constraints are included: price limits (no fill when sealed) and suspensions (no fill without a quote). ⚠️ ST status uses the current list as an approximation (no public source for day-by-day history) — ST names are about 3.6% of the market and the effect is limited to price-limit days. ⚠️ NOT included: market impact and capacity. ⚠️ Past performance does not indicate future results; research use only, not investment advice. Paid tier — Pro (¥99) and above, 100 calls/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.
