Trading calendar (market open/closed) API
A-share trading calendar: for each date, whether the market is open, and whether it is the LAST trading day of the week / month / quarter / year (useful for settlement, expiry and rebalancing dates). NOT the same as /v1/calendar, which lists per-stock corporate events. Three query modes (pick one): no params = current month; date=YYYY-MM-DD = a single day; start+end = a range, or year=2026 = a whole year. Set trading_only=true to get market-open days only (~242 rows a year). limit is filled in automatically for year/range queries, so results are never silently truncated; use offset to page. data is a formatted table; read structured for programmatic access. Columns: date / is_trading_day / is_week_last / is_quarter_last / is_year_last / is_month_last. Free tier (no key required), but calls still count toward usage and rate limits.

| Parameter | Type | Required | Description |
|---|---|---|---|
| date | string | No | A single day, YYYY-MM-DD (leave blank to use year / start+end; all blank = current month) |
| start | string | No | Range start date YYYY-MM-DD (pair with end) |
| end | string | No | Range end date YYYY-MM-DD (pair with start) |
| year | string | No | A whole year, e.g. 2026 (mutually exclusive with date and start+end) |
| trading_only | boolean | No | true = market-open days only |
| limit | integer | No | Row cap (0 = automatic: year/range queries are filled up to 400, so nothing is truncated) |
| offset | integer | No | Skip the first N rows (paging) |

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 <your key>. ⚠️ 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 15/min regardless of type. ⚠️ Also, anonymous calls are capped at 250 bars per request and 100k rows per day — use an API key for the full 1212 bars or unlimited daily volume.
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 39 tools covering quotes, financials, screening, sectors and macro.
