K-line (D/W/M) API

Historical K-line data (daily / weekly / monthly). ⚠️ The turnover rate field is named `turnover` (in %) — same as /v1/quote and /v1/snapshot (renamed from `exchange` on 2026-09-26). ⚠️ The price basis is fixed at forward-adjusted (no gap on ex-dividend days; no `adjust` parameter) — do not re-adjust (double adjustment).

Response example

Sample: `GET /v1/kline?code=sh600667&period=day&count=3` (real response, 2026-09-26, truncated). `volume` is in shares, `amount` in CNY, `turnover` is the turnover rate in %.

}
Response

Unified envelope: { ok, endpoint, tier, elapsed_ms, source, data }

Rows live in `data`; when upstream returns nothing you get `ok:false` and the call is not counted.

Rate limits & quota

Free endpoints need no key (anonymous 5/min; solve one PoW challenge for 60/min). Paid tiers: Trial 30 · Standard 120 · Pro 300 · Unlimited 600 per minute; buyout packs are capped by total calls and never expire.

FAQ

Is the K-line data forward-adjusted (前复权) or raw?

Forward-adjusted (前复权). There is no gap on ex-dividend days — we verified 6 ex-dividend dates (COSCO Shipping Holdings 7.27%, China Shenhua 6.14%, Kweichow Moutai 2.37%, ICBC 2.31% and others) and none showed a gap. We do not offer an `adjust` parameter, nor unadjusted / backward-adjusted data.

How many bars can I request at most?

Measured ceiling: 1212 bars (about 5 years of daily data). Larger `count` values (e.g. 2000 or 5000) still return 1212 — that is all the history the upstream holds. Default is 30.

Do you support minute bars (1m / 5m / 60m)?

No. `period` accepts only `day`, `week` and `month`. Minute-level data is outside our scope.

Why do my moving averages not match another platform?

Three usual causes: ① adjustment basis — we are forward-adjusted, so against an unadjusted source the difference appears exactly on windows that span an ex-dividend date; ② a different window start date (our last bar is the latest trading day); ③ a different adjustment reference date on their side. Short windows (MA5 / MA10) normally agree; differences show up in long windows that cross an ex-dividend date (e.g. MA120).

Is the `turnover` field the "exchange"?

No. `turnover` is the turnover rate in %. It was renamed from `exchange` on 2026-09-26 because the old name read like "exchange" the venue. It has the same name and value in `/v1/quote` and `/v1/snapshot`.

General (applies to every endpoint)

Do these endpoints need an API key?

Free endpoints do not: health, challenge, quote, kline, hot, market-overview and changedist work anonymously. Paid endpoints do: send `Authorization: Bearer `. ⚠️ The anonymous allowance is tiered by caller type: browsers (humans) get 5/min; scripts, SDKs and AI Agents (curl, requests, axios, openai user-agent strings) get 2/min — automated traffic is easier to abuse. Solving one PoW challenge (`GET /v1/challenge`, then send the `X-PoW` header) raises it to 60/min regardless of type.

Am I charged when the upstream returns nothing or errors?

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.

How fresh is the data?

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.

Can I request several stocks in one call?

No. `code` is a single-value parameter — one stock per call. For batches, issue concurrent calls and respect your tier per-minute limit.
