# Limit-up pool (all limit-up stocks with reason / seal amount / main capital) API
 Short-term trading — the full limit-up pool for the session: every limit-up stock in one call, with `reason` limit-up reason / `seal_amount` & `seal_amount_max` seal amounts / `main_net` / `main_buy`·`main_sell` main capital / `amount` / `concepts` / `float_cap` / `turnover` / `streak` board count / `pct`. `mode=limit` (default). ⚠️ Empty `date` = realtime; `YYYY-MM-DD` = that trading day (must be a real trading day, otherwise empty). ⚠️ For the ladder structure / sector mainlines use `/v1/review`. `data` is always a row array (DataFrame-ready); the count is the top-level `count`. Paid tier — Standard (¥29.9) and above.
 Pro `GET /v1/limit-up`
 Signature
```
GET /v1/limit-up?mode=list
```
 One-liner

```
curl "https://api.ashareapi.com/v1/limit-up?mode=list&key=YOUR_KEY"
```
 Parameters: `mode · 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/limit-up?mode=list"

# 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/limit-up?mode=list&key=YOUR_KEY"
```
 Python

```
import requests

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

```
const r = await fetch("https://api.ashareapi.com/v1/limit-up?mode=list", {
 headers: { Authorization: "Bearer YOUR_KEY" },
});
console.log(await r.json());
```

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

| | mode | string | No | list or detail

| | date | string | No | Date YYYY-MM-DD (blank = latest trading day)

 `mode` string
 list or detail

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

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