What is stock-data-fetch?

A data-fetching workflow for prices, company metrics, cryptocurrency, commodities, indexes, and market news across several regions and backup sources.

Use it to retrieve snapshots for US, A-share, Hong Kong, and cryptocurrency markets, plus selected commodities, indexes, and news. API keys, where required, are read from environment variables.

It reduces the need to collect financial data manually from different services and can use fallback sources when one fails.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00062	$0.01414
Opus 5	$0.00031	$0.00707
Sonnet 5	$0.00012	$0.00283
Haiku 4.5	$0.00006	$0.00141

Measured 9d ago against content hash 3ab43321ab1b, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

stock-data-fetch scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Stock Data Fetch

关于 snapshot 命令：下文的 snapshot 是一个可选的本地封装脚本（自己用 Python/shell 包一层多源 failover 即可），不是随仓库分发的二进制。不想写脚本也没关系——本文档把每个市场的免 key 直连端点都列出来了，直接 curl 就能用。所有需要 key 的源（FMP/Finnhub/Longbridge）请把 key 放进环境变量，不要写死在代码里。

Quick Start

snapshot TICKER [--no-news] [--no-commit]

One command. All markets. Automatic failover.

Lessons Learned (Battle Scars)

Never Use These (in this network)

yfinance — rate limited + SSL errors. Hermes docs explicitly warn against it
akshare / akshare-one — both call eastmoney.com which is proxy-blocked
Google News RSS — guaranteed timeout
Binance — HTTP 451 (legal block)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
