Quant factor library (88 factors + 22 presets) API
List every available stock-selection factor (code / Chinese name / unit / description / category), plus 22 presets and the usage rules. Feed factors to `/v1/screen` as an expression, e.g. `intersect([PE_TTM > 0, PE_TTM < 20, ROETTM > 15])`. Multiple conditions are combined with `intersect([...])` (AND); the only operators are `> < >= <= = !=` — `between`, `in` and `OR` are not supported. ⭐ Historical cross-sections are supported: `/v1/screen?date=YYYY-MM-DD` returns factor values for any past trading day (data exists from 2016-08-08), so you can chain factor → screen → backtest. ⚠️ Eight usage rules apply — most importantly `PE_TTM > 0` must come first (loss-making companies have negative PE and would otherwise be picked as "low PE"). ⚠️ This is a static list (no heavy quota). Paid tier — Standard (¥29.9) and above.

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.
Set up MCP once, then just ask the AI — it calls the endpoint itself. MCP exposes 26 tools covering quotes, financials, screening, sectors and macro.
