What is financial-data-fetcher?

A financial research tool that retrieves company financial statements, valuation measures, financial ratios, ETF listings, and daily ETF trading data.

Use it to check revenue, profit, margins, return on equity, price-to-earnings and price-to-book ratios, or compare companies and ETFs.

It removes the need to gather these figures manually from separate data sources when researching stocks or funds.

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	$0.00112	$0.01352
Opus 5.5	$0.00045	$0.00541
Sonnet 5.5	$0.00022	$0.00270
Haiku 4.5	$0.00011	$0.00135

Security

Grade A, and why

financial-data-fetcher scanned grade A with 0 findings 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 2mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Financial Data Fetcher

Fetch financial statements, valuation metrics, and ETF data. Tushare Pro is the primary data source (more stable, richer data); AKShare as fallback and for ETFs.

This skill orchestrates the fetch scripts shipped by the sibling tushare-data and stock-market-data skills. Install those first, then point the variables below at wherever you installed them.

Setup

export TUSHARE_TOKEN=<your Tushare Pro token>       # never hard-code; see the tushare-data skill
PY=python3                                          # a python3 with tushare/pandas/akshare (e.g. stock-market-data/.venv/bin/python3)
SKILLS=~/.claude/skills                             # where these skills are installed
TUSHARE_SCRIPT=$SKILLS/tushare-data/scripts/fetch_tushare.py

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.
