# L2 main-capital four-way split (minute-level: active/passive × buy/sell, plus buy/sell average price) API
 Minute-level four-way main-capital split: main buying is split into active buy + passive buy, main selling into active sell + passive sell, one row per minute. Rows (amounts in CNY): time / trades / net / main_buy / main_sell (negative) / active_buy / passive_buy / active_sell / passive_sell. Top-level fields (siblings of data): day / points / mode (realtime | history) / summary (whole-day totals) / buy_avg_price / sell_avg_price (volume-weighted average price of main buying / selling). ⭐ How to read it: high active_buy = someone is sweeping the offer; high passive_buy = your bids are being hit; concentrated active_sell = active distribution; heavy passive_sell = offers being lifted. Only the four-way split tells you who is hitting whom. ⭐ Versus /v1/bigorder-flow: flow is the tick-by-tick trade list (which specific trade; today only, ≤200 per call); this endpoint is the minute aggregation (rhythm + average price, history supported, no row cap). ⚠️ Pass date for a past session; omit for today. ⚠️ This is a capital-flow metric (split by trade direction) — not an order queue, not a ten-level order book. Paid tier — Unlimited only.

 One-liner

```
curl "https://api.ashareapi.com/v1/bigorder-split?code=sh600667&date=2026-09-16&key=YOUR_KEY"
```
 Parameters: `code * · date` * = 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-split?code=sh600667&date=2026-09-16"

# 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-split?code=sh600667&date=2026-09-16&key=YOUR_KEY"
```
 Python

```
import requests

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

```
const r = await fetch("https://api.ashareapi.com/v1/bigorder-split?code=sh600667&date=2026-09-16", {
 headers: { Authorization: "Bearer YOUR_KEY" },
});
console.log(await r.json());
```

## Response fields
 The table below is captured from **real API calls** (not inferred): each row gives the field name, its type and one real sample value, so you can align your parser.
 Located in: `data` Envelope: `ok / endpoint / tier / elapsed_ms / source` Probed: `2026-10-20`
 |
| | Field | Type | Real sample value

| | time | str | 09:30

| | trades | num | 177

| | net | num | 11376349

| | main_buy | num | 110626139

| | main_sell | num | -99249790

| | active_buy | num | 53451977

| | passive_buy | num | 57174162

| | active_sell | num | 54263905

| | passive_sell | num | 44985885

 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.
