# Institutional participation board (whole market: which stocks institutions traded on the dragon-tiger list) API
 Institutional participation board (whole market): every stock that institutional seats traded on the dragon-tiger list on a given session, in one call (~51 stocks per session). data rows (amounts in CNY): code / name / net_buy (institutional net buying — ⚠️ negative means institutions were net sellers) / join_num (seats involved) / change_pct (%) / turnover (CNY) / amplitude (%) / turnover_rate (%) / float_cap (CNY) / market_cap (CNY) / fengkou_plates (theme plate codes; the source does not provide plate names). Top-level meta (siblings of data): date (the actual session) / total / returned / sort / unit. ⭐ How to use it: sort=net_buy shows who institutions really bought today (negatives are sells); pair with /v1/lhb-seats to drill from a stock down to which broker branch bought it. ⭐ Versus /v1/lhb: that one is the split board (stocks listed by change / turnover criteria); this one keeps only the institution-involved names and gives the institutional amount directly — no manual cross-checking. ⚠️ The dragon-tiger list is post-close data: leave date empty for the latest session and trust the returned date. ⚠️ net_buy is a net figure (buy − sell) and can be negative (26 of the 51 rows were negative on the measured session) — ⛔ do not take the absolute value as buying volume. Paid tier — Unlimited only.

GET /v1/lhb-agency?date=2026-09-16
```
 One-liner

```
curl "https://api.ashareapi.com/v1/lhb-agency?date=2026-09-16&key=YOUR_KEY"
```
 Parameters: `date · sort · 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/lhb-agency?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/lhb-agency?date=2026-09-16&key=YOUR_KEY"
```
 Python

```
import requests

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

```
const r = await fetch("https://api.ashareapi.com/v1/lhb-agency?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.

 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.
