# Whole-market single-day K-line (all A-shares, 5,000+ in one call) API
 Every A-share stock's daily bar for one trading day in a single call (5,000+ symbols) — built for whole-market incremental updates, replacing a 5,000-request loop with one request. Typical use: call it once after the close to ingest the day's whole-market bars. Scope: A-share stocks only (5,572) from 2016-08-08, raw unadjusted prices; ETFs, convertible bonds, indices, sectors, Hong Kong, US, futures and FX are not included. Latest data is available up to the previous trading day (intraday same-day data is not available). ⚠️ Two hard limits: available on the Pro (¥199) and Unlimited tiers only, and 1 call counts as 500 calls of quota (one request moves 5,000+ symbols, far beyond a single-symbol endpoint). A separate daily cap applies (Pro 200 / Unlimited 1,000 per day). Eight columns: `code` `time` `open` `high` `low` `close` `volume` `amount`. Response is roughly 785 KB per call.
 Pro `GET /v1/market-kline`
 Signature
```
GET /v1/market-kline?date=2026-09-16&limit=10
```
 One-liner

```
curl "https://api.ashareapi.com/v1/market-kline?date=2026-09-16&limit=10&key=YOUR_KEY"
```
 Parameters: `date * · limit · offset · codes` * = required

## Quick start
 Replace the key below with yours (free endpoints need no key):
 curl

```
# 推荐：Authorization 头（密钥不进日志）
curl -H "Authorization: Bearer YOUR_KEY" \
 "https://api.ashareapi.com/v1/market-kline?date=2026-09-16&limit=10"

# 快速测试：直接浏览器打开（?key= 会留在日志/历史里，别用于生产）
curl "https://api.ashareapi.com/v1/market-kline?date=2026-09-16&limit=10&key=YOUR_KEY"
```
 Python

```
import requests

r = requests.get(
 "https://api.ashareapi.com/v1/market-kline",
 headers={"Authorization": "Bearer YOUR_KEY"},
 params={"date": "2026-09-16"},
 timeout=30,
)
print(r.json())
```
 JavaScript

```
const r = await fetch("https://api.ashareapi.com/v1/market-kline?date=2026-09-16&limit=10", {
 headers: { Authorization: "Bearer YOUR_KEY" },
});
console.log(await r.json());
```

## Parameters
 |
| | Parameter | Type | Required | Description

| | date | string | Yes | Date YYYY-MM-DD (blank = latest trading day)

| | limit | integer | No | Number of rows, default 30

| | offset | integer | No | 分页偏移（配合 limit 使用）

| | codes | string | No | 可选：只取指定股票，逗号分隔（如 sh600519,sz000001；省略 = 全市场）

 `date` string Yes
 Date YYYY-MM-DD (blank = latest trading day)

 `limit` integer
 Number of rows, default 30

 `offset` integer
 分页偏移（配合 limit 使用）

 `codes` string
 可选：只取指定股票，逗号分隔（如 sh600519,sz000001；省略 = 全市场）

 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 — 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.

## FAQ

### 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 **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.

 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.

 How do I use this from Claude / Cursor / ChatGPT?
 Set up MCP once, then just ask the AI — it calls the endpoint itself. MCP exposes 31 tools covering quotes, financials, screening, sectors and macro.
