产业链（主题/图谱/个股定位） API
A 股产业链数据（183 个产业链主题）：mode=list 主题列表 · mode=graph&topic=超级电容 → 产业链图谱（关联个股 + 所属节点 + 产业链位置 上游/中游/下游）· mode=stock&code=sh600667 → 个股所属产业链（主题 / 节点 / 位置 / 关联度 / 业务描述）。用户问『产业链/上下游/某公司处于链上什么位置/这个主题有哪些公司』时用。

modestringtopicstringcodestringUnified 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.
Free endpoints need no key (anonymous 5/min; solve one PoW challenge for 60/min). Paid tiers: Trial 30 · Standard 120 · Pro 300 · Unlimited 600 per minute; buyout packs are capped by total calls and never expire.

General (applies to every endpoint)
Free endpoints do not: health, challenge, quote, kline, hot, market-overview and changedist work anonymously. Paid endpoints do: send `Authorization: Bearer
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.
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.
No. `code` is a single-value parameter — one stock per call. For batches, issue concurrent calls and respect your tier per-minute limit.
Set up MCP once, then just ask the AI — it calls the endpoint itself. MCP exposes 24 tools covering quotes, financials, screening, sectors and macro.
