Tail-end capital grab (whole-market ranking) API

Where late-session money is grabbing: about 292 stocks market-wide with grab amount, theme and change. data rows: code / name / fund_tag (e.g. fund, empty = none) / theme / change_pct (%) / chase_amount (CNY) / masked / raw. A few symbols are withheld and carry masked=true while the amount stays complete; do not treat those rows as tradable symbols. Results are re-sorted by sort (default chase_amount descending), so the first row is the largest grab of the day. Paid tier - Unlimited only.

One-liner

Parameters: limit · sort* = 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/tail-chase?limit=10"

# 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/tail-chase?limit=10&key=YOUR_KEY"
Python
import requests

r = requests.get(
    "https://api.ashareapi.com/v1/tail-chase",
    headers={"Authorization": "Bearer YOUR_KEY"},
    params={},
    timeout=30,
)
print(r.json())
JavaScript
const r = await fetch("https://api.ashareapi.com/v1/tail-chase?limit=10", {
  headers: { Authorization: "Bearer YOUR_KEY" },
});
console.log(await r.json());

Parameters

limitinteger
Number of rows, default 30
sortstring
排序:chase_amount / change_pct

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 <your key>. ⚠️ 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.

Use it from an AI Agent?
