# Call auction (intraday series / historical ticks / auction volume + "touched limit-up" flag) API
 The 09:15–09:25 call auction for a single stock, including a "touched limit-up during auction" flag. `mode=stock` (default) intraday auction series, minute ticks covering 09:15–09:24 — each row has `time` / `price` / `stage` auction phase (0 = cancellable 09:15–09:20 · 1 = non-cancellable 09:20–09:25) / `volume` cumulative volume; `mode=stock-history` second-level historical ticks (requires `date`); `mode=volume` intraday auction volume / net amount (single point). ⭐ `is_limit_up` at the top level = the "touched limit-up" flag (auction high ≥ limit-up price; the limit-up price is taken from a raw source field, so main board 10% / ChiNext·STAR 20% / ST 5% / Beijing Exchange 30% are correct by construction). Also returns `up_px` limit-up price / `down_px` limit-down price / `open_px` the 09:25 match price / `preclose_px` previous close / `hprice` auction high. ⚠️ `mode=stock` covers today only; for history use `mode=stock-history` with a `date` (must be a real trading day). `data` is always a row array (DataFrame-ready). Paid tier — Standard (¥29.9) and above.
 Pro `GET /v1/auction`
 Signature
```
GET /v1/auction?code=sh600667&mode=list
```
 One-liner

```
curl "https://api.ashareapi.com/v1/auction?code=sh600667&mode=list&key=YOUR_KEY"
```
 Parameters: `mode · 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/auction?code=sh600667&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/auction?code=sh600667&mode=list&key=YOUR_KEY"
```
 Python

```
import requests

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

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

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

 `mode` string
 list or detail

 `code` string Yes

 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.
