# a-stock-data
A 股全栈数据工具包 — 7 层架构 · 27 个端点 · 13 个数据源 · 零第三方数据封装依赖
一个自包含的 Skill 文件,把分散在 13 个数据源里的 A 股原始数据整合成 AI 编程助手直接能用的工具集。你不用再背 mootdx 的 K 线参数、东财的 PDF Referer 头、iwencai 的 X-Claw 鉴权——全部封装好了。
> **V3.2.2 修复(2026-06-03):** ① **概念板块归属(#18)**——百度 PAE `getrelatedblock` 失效(`ResultCode 10003`)→ 改用东财 `slist` 一次拿全个股所属板块(行业/概念/地域 + BK码 + 涨跌幅 + 龙头股);② **巨潮公告 orgId(#19)**——硬编码 `gssx0{code}` 导致大量 601xxx 股票查不到公告 → 改为动态查官方映射表 `szse_stock.json`(6198 只股);③ 修复综合示例对已删函数 `baidu_fund_flow_history` 的调用;④ §4.5/§5.1 加大陆住宅 IP 间歇风控说明。
>
> **V3.2(2026-05-30):** ① **数据源优先级 + 东财防封**——优先用通达信(mootdx)/腾讯(不封 IP),东财仅用于其独有数据,并新增统一节流入口 `em_get()`,所有东财接口内置串行限流(间隔≥1s+随机抖动)+ 会话复用,AI 抄代码即自带防封;② **财联社快讯下线(#14)**——`cls.cn` 旧 API 全面 404,改用东财全球资讯。
>
> **V3.1 修复(2026-05-19):** 替换 4 个失效接口(百度 PAE 资金流→东财 push2、大宗交易/机构席位报表名更新)+ 修复东财全球资讯和巨潮公告参数变更。
>
> **V3.0 Breaking Change:** 彻底移除 akshare 依赖,所有数据源改为直连 HTTP API。新增资金面/筹码层。
> 兼容 [Claude Code](https://github.com/anthropics/claude-code) · [Codex](https://github.com/openai/codex) · [OpenClaw](https://github.com/anthropics/openclaw)
>
> Skill 文件本质是结构化 Markdown + 内嵌 Python,任何支持上下文注入的 AI 编程助手都能用。

## V3.2.2 亮点
| 变化 | 说明 |
|------|------|
| **概念板块归属换源(#18)** | 百度 PAE `getrelatedblock` 失效(`ResultCode 10003`)→ 改用东财 `slist`,一次请求拿全个股所属板块(行业/概念/地域 + BK码 + 涨跌幅 + 龙头股),零鉴权走 `em_get` 限流 |
| **巨潮公告 orgId 动态化(#19)** | 硬编码 `gssx0{code}` 导致大量 601xxx 股票(平安/工行/中石油等)查不到公告 → 动态查官方映射表 `szse_stock.json`(6198 只股,模块级缓存),硬编码降为 fallback |
| **修复综合示例隐藏崩溃** | 示例仍调用 v3.1 已删除的 `baidu_fund_flow_history` → 改为 `eastmoney_fund_flow_minute` |
| **大陆住宅 IP 风控说明** | §4.5 资金流 / §5.1 新闻 加 ⚠️:部分大陆住宅 IP 会被东财间歇风控(`HTTP 000`/空),非代码问题,重试或换网络即可 |
| **数据源优先级原则**(V3.2 起) | 明确「能用通达信(mootdx)/腾讯就别用东财」——前两者 TCP/HTTP 实测不封 IP,可放心高频;东财仅用于其独有数据 |
| **东财统一限流防封** | 新增节流入口 `em_get()`,所有东财端点(datacenter/push2/reportapi/search/np-weblist)改用它,内置串行限流(间隔≥1s+随机抖动)+ 会话复用,批量抄代码即自带防封 |
| **东财风控阈值文档化** | SKILL 新增「数据源优先级 & 东财防封」章节,列出触发封禁的阈值(每秒>5/并发≥10/1分≥200/5分≥300)与防封铁律 |
| **财联社快讯下线(#14)** | `cls.cn` 旧 API 全面 404,标注弃用,改用东财全球资讯 |
---
## 数据源优先级(V3.2 重排,按封 IP 风险)
> **原则:行情/K线/实时价/市值/财务能从 mootdx 或腾讯拿到的,一律优先用它们(不封 IP)。东财只用于它独有、别处拿不到的数据,且全部走 `em_get()` 内置限流。**
| 优先级 | 数据源 | 协议 | 封 IP 风险 | 用途 |
|--------|--------|------|-----------|------|
| **1(首选)** | mootdx(通达信) | TCP 7709 | **不封 IP** | K线/五档/逐笔/财务快照/F10 |
| **2(首选)** | 腾讯财经 | HTTP | **不封 IP** | 实时价/PE/PB/市值/换手率/涨跌停/指数/ETF |
| 3 | 同花顺热点/北向 | HTTP | 极低(零鉴权) | 强势股/题材归因/北向资金 |
| 4 | 百度股市通 | HTTP | 极低 | K线(带 MA5/10/20)|
| 5 | 新浪财经 | HTTP | 低 | 财报三表 |
| 6 | 巨潮 cninfo | HTTP | 低 | 公告全文 |
| 7 | 同花顺一致预期 | HTTP | 低(需 UA) | EPS 一致预期 |
| 8 | iwencai | OpenAPI | 低(需 Key) | NL 语义搜索 |
| **末位(仅独有数据)** | **东财** datacenter/push2/reportapi/search/np-weblist | HTTP | **中 — 有风控会封 IP** | 龙虎榜/解禁/两融/大宗/股东户数/分红/资金流/研报/个股新闻/全球资讯(已统一走 `em_get()` 限流) |
> **架构原则:** 除 mootdx(TCP 二进制协议)外,全部直连 HTTP API,零第三方数据封装依赖。**东财系接口有访问频率风控,所有调用统一经 `em_get()` 串行限流防封;批量任务请调大 `EM_MIN_INTERVAL`。**

## FAQ
**Q: mootdx 和腾讯有什么区别?**
互补。mootdx = 交易层(价格 + 盘口 + K 线),腾讯 = 估值层(PE / PB / 市值 / 换手率 / 涨跌停价)。两者都不封 IP。
**Q: 在海外服务器跑,mootdx 超时?**
mootdx 走 TCP 直连通达信行情服务器,需国内 IP 才稳定。海外环境建议走代理或切换到 yfinance。
**Q: 腾讯 API 字段 43 是 PB 吗?**
不是。43 = 振幅%,46 = PB。网上大量教程写错了,这里是实测校准结果。
**Q: V3.0 为什么移除 akshare?**
akshare 本质是对东财/同花顺/新浪等公开 API 的封装,中间层增加了故障点(版本兼容 bug、pandas 3.0 ArrowInvalid 等)。V3.0 直连底层 HTTP API,零中间依赖,更稳定可控。
**Q: 行业板块为什么从同花顺换成东财?**
同花顺 `stock_board_industry_summary_ths` 接口 2026 年初加了反爬 401。东财 push2 行业板块(`m:90+t:2`)是完美替代,零鉴权且字段更丰富。
**Q: iwencai 返回 401?**
检查:(1) API Key 有效性 (2) 是否携带了 X-Claw-* Headers。SkillHub 2.0 后强制要求。
**Q: 同花顺热点 reason 字段为空?**
盘后数据还没更新,15:30 之后再调。个别 ST 股没有人工标注,`dropna` 过滤即可。
**Q: 百度股市通 ResultCode 不稳定?**
已知坑——有时返回 int `0`,有时返回 string `"0"`。代码里用 `str()` 统一比较即可。
**Q: 东财资金流/个股新闻偶尔返回空或 HTTP 000?(#18)**
部分**大陆住宅宽带 IP** 会被东财 push2/search-api 连接级间歇风控(表现 `HTTP 000` 连接被拒、或新闻只返回 `passportWeb` 无文章)。**这不是代码问题**——同一代码在其他网络/时段实测正常。对策:隔几分钟重试、换网络环境(手机热点)、调大 `EM_MIN_INTERVAL` 降频。日级资金流也可用 mootdx 量价数据务实替代。
**Q: 北向资金历史只有几天?**
V2.1 改为本地自缓存。每次调用自动积累,越跑越丰富。首次运行只有当天数据。
**Q: 不用 Claude Code,能用吗?**
能。SKILL.md 本质是 Markdown + 内嵌 Python 代码。Codex、OpenClaw 或任何 AI 编程助手都能读取。你也可以直接把 Python 代码段复制出来在自己的脚本里跑。

# a-stock-data
Full-stack data toolkit for China A-Share market — 7-layer architecture · 27 endpoints · 13 data sources · zero third-party data wrapper dependencies
A self-contained Skill file that consolidates raw A-share data from 13 sources into a ready-to-use toolkit for AI coding assistants. No need to memorize mootdx candlestick parameters, Eastmoney PDF Referer headers, or iwencai X-Claw authentication — it's all handled.
> **V3.2.2 Fix (2026-06-03):** ① **Sector/concept membership (#18)** — Baidu PAE `getrelatedblock` is dead (`ResultCode 10003`) → switched to Eastmoney `slist`, fetching all of a stock's sectors (industry/concept/region + BK code + change% + leading stock) in one request. ② **cninfo filing orgId (#19)** — hardcoded `gssx0{code}` made many 601xxx tickers return zero filings → now resolves the real orgId dynamically from the official map `szse_stock.json` (6198 stocks). ③ Fixed a crash in the combined example calling the removed `baidu_fund_flow_history`. ④ Added notes on intermittent Eastmoney throttling for some mainland residential IPs.
>
> **V3.2 (2026-05-30):** ① **Data-source priority + Eastmoney anti-ban** — prefer mootdx (TDX) / Tencent (never IP-banned); use Eastmoney only for its exclusive data, all routed through a new throttled `em_get()` (serial rate-limit ≥1s + jitter + session reuse) so copied code is ban-safe by default. ② **Cailianpress (cls.cn) deprecated (#14)** — old API returns 404, replaced by Eastmoney global news.
>
> **V3.1 Fix (2026-05-19):** Replaced 4 broken endpoints (Baidu PAE fund flow → Eastmoney push2, block trade/institution report name updates) + fixed Eastmoney global news and cninfo filing parameter changes.
>
> **V3.0 Breaking Change:** Completely removed akshare dependency. All data sources now use direct HTTP API calls. Added capital flow / ownership layer.
> Compatible with [Claude Code](https://github.com/anthropics/claude-code) · [Codex](https://github.com/openai/codex) · [OpenClaw](https://github.com/anthropics/openclaw)
>
> The Skill file is structured Markdown + embedded Python. Any AI coding assistant with context injection can use it.

## V3.2.2 Highlights
| Change | Description |
|--------|-------------|
| **Sector membership re-sourced (#18)** | Baidu PAE `getrelatedblock` is dead (`ResultCode 10003`) → switched to Eastmoney `slist`; one request returns all of a stock's sectors (industry/concept/region + BK code + change% + leading stock), no auth, throttled via `em_get` |
| **cninfo orgId resolved dynamically (#19)** | Hardcoded `gssx0{code}` made many 601xxx tickers (Ping An / ICBC / PetroChina, etc.) return zero filings → now resolves the real orgId from the official map `szse_stock.json` (6198 stocks, module-level cache), hardcode kept as fallback |
| **Fixed hidden crash in combined example** | Example still called the v3.1-removed `baidu_fund_flow_history` → switched to `eastmoney_fund_flow_minute` |
| **Mainland residential IP throttling note** | §4.5 fund flow / §5.1 news: some mainland residential IPs hit intermittent Eastmoney throttling (`HTTP 000` / empty) — not a code bug, retry or switch network |
| **Data-source priority principle** (since V3.2) | Prefer mootdx (TDX) / Tencent — both never IP-banned in practice, safe for high-frequency use. Use Eastmoney only for its exclusive data |
| **Unified Eastmoney throttling** | New `em_get()` entry point; all Eastmoney endpoints (datacenter/push2/reportapi/search/np-weblist) route through it with built-in serial rate-limit (≥1s + jitter) + session reuse — copied code is ban-safe by default |
| **Eastmoney rate-limit documented** | New "Data-source priority & Eastmoney anti-ban" section lists ban thresholds (>5/s, ≥10 concurrent, ≥200/min, ≥300/5min) and anti-ban rules |
| **Cailianpress deprecated (#14)** | cls.cn old API returns 404 — marked deprecated, replaced by Eastmoney global news |
---
## Data Source Priority (V3.2 re-ranked by IP-ban risk)
> **Principle: anything available from mootdx or Tencent (quotes / K-line / live price / market cap / financials) must use them first (never IP-banned). Eastmoney is only for its exclusive data, all routed through the throttled `em_get()`.**
| Priority | Source | Protocol | IP Ban Risk | Use |
|----------|--------|----------|-------------|-----|
| **1 (top)** | mootdx (TDX) | TCP 7709 | **Never banned** | K-line / order book / ticks / financials / F10 |
| **2 (top)** | Tencent Finance | HTTP | **Never banned** | Live price / PE / PB / market cap / turnover / index / ETF |
| 3 | THS Hot Stocks / Northbound | HTTP | Very low (zero auth) | Hot stocks / themes / northbound flow |
| 4 | Baidu Finance | HTTP | Very low | K-line (w/ MA5/10/20) |
| 5 | Sina Finance | HTTP | Low | Financial statements |
| 6 | cninfo | HTTP | Low | Filings |
| 7 | THS Consensus EPS | HTTP | Low (UA required) | Consensus EPS |
