# L2 大单成交明细（含主动/被动拆分 · 不限量版专属） API
 逐笔大单成交：单只票当日每一笔成交额 ≥ 阈值的大单，并按主动 / 被动 × 买 / 卖四方向标注。

data 行字段：time（成交时间）/ direction（1 被动卖 · 2 主动买 · 3 被动买 · 4 主动卖）/ direction_cn（中文方向）/ volume（手）/ amount（元）/ avg_price（成交均价）。
顶层 meta：money_threshold（当前阈值，如 100万）/ total（当日满足阈值的总笔数）/ returned 本次返回条数 / truncated 是否被截断 / summary 四方向金额合计（注意 summary_scope=returned_rows，被截断时只是本次样本的合计）。

⭐ 怎么读：主动买 占比高 = 有人在主动扫货；被动买 多 = 挂单被砸；主动卖 集中 = 主动出货。四方向合起来才能分清「谁在打谁」。
money 取 0~4 → 30万 / 50万 / 100万 / 300万 / 1000万。
⚠️ 仅当日：非交易日/盘前返回最近一个交易日，日期看返回行里的 time。
⚠️ 单次最多约 200 笔（上游限制）：total 大于 returned 时请用 money 抬高阈值缩小范围。
⚠️ 这是成交口径（已成交的大单），不是逐笔委托、也不是十档盘口。
 Pro `GET /v1/bigorder-flow`
 Signature
```
GET /v1/bigorder-flow?code=sh600667&money=0
```
 One-liner

```
curl "https://api.ashareapi.com/v1/bigorder-flow?code=sh600667&money=0&key=YOUR_KEY"
```
 Parameters: `code * · money · limit` * = 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/bigorder-flow?code=sh600667&money=0"

# 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/bigorder-flow?code=sh600667&money=0&key=YOUR_KEY"
```
 Python

```
import requests

r = requests.get(
 "https://api.ashareapi.com/v1/bigorder-flow",
 headers={"Authorization": "Bearer YOUR_KEY"},
 params={"code": "sh600667"},
 timeout=30,
)
print(r.json())
```
 JavaScript

```
const r = await fetch("https://api.ashareapi.com/v1/bigorder-flow?code=sh600667&money=0", {
 headers: { Authorization: "Bearer YOUR_KEY" },
});
console.log(await r.json());
```

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

| | code | string | Yes | Stock code with market prefix: sh600667 (SH), sz000001 (SZ), hk00700 (HK), usAAPL (US)

| | money | integer | No | 金额阈值档：0=30万 1=50万 2=100万 3=300万 4=1000万

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

 `code` string Yes
 Stock code with market prefix: sh600667 (SH), sz000001 (SZ), hk00700 (HK), usAAPL (US)

 `money` integer
 金额阈值档：0=30万 1=50万 2=100万 3=300万 4=1000万

 `limit` integer
 Number of rows, default 30

 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 39 tools covering quotes, financials, screening, sectors and macro.
