FinSkills One — Unified Financial Data

Use the Finskills REST API (https://finskills.net) as the single entry point for all financial data: stocks, crypto, forex, macro, commodities, news, SEC filings, ETFs, analyst ratings, alternative data (Congress / insider / WSB).

This skill consolidates 80+ endpoints behind one API key, with automatic multi-source fallback (Yahoo Finance, CoinGecko, FRED, World Bank, SEC EDGAR, Frankfurter, FDIC, FEMA, etc.) and a unified response envelope.

Authentication

All requests require the X-API-Key header. If the user has not provided one, ask for it, then point them to https://finskills.net/register.

GET /v1/free/crypto/price/bitcoin HTTP/1.1
Host: finskills.net
X-API-Key: fh_live_xxxxxxxxxxxxxxxxxxxx

Base URL: https://finskills.net

Unified response envelope for every endpoint:

{
  "success": true,
  "data": { ... },
  "source": "yahoo|coingecko|fred|...",
  "sources": ["primary", "fallback"],
  "cached": false,
  "timestamp": "2026-05-09T12:34:56.000Z"
}

On error: { "success": false, "error": { "code": "...", "message": "..." } }. HTTP status mirrors the failure (401 missing/invalid key, 403 quota, 404 symbol unknown, 429 rate-limited, 5xx upstream).

Prefer /v1/free/... whenever the data exists there — it requires no third-party subscription. Fall back to /v1/... (premium-routed) only when the free variant does not cover the use case.

Universal Usage Rules

Always include X-API-Key. Never log it back to the user verbatim — refer to it as "your API key".
For crypto, use CoinGecko coin IDs (bitcoin, ethereum, solana), not tickers (BTC, ETH).
For stocks, use standard tickers (AAPL, BRK-B, MSFT). Hong Kong: 0700.HK. Tokyo: 7203.T.
For SEC, use the CIK as a string with leading zeros stripped or padded to 10 (the API accepts both): 320193 or 0000320193.
For commodities, use Yahoo futures tickers: CL=F (WTI), GC=F (gold), SI=F (silver), ZW=F (wheat), NG=F (natgas), HG=F (copper).
For FRED series in macro/commodity, capitalize: GDP, CPIAUCSL, FEDFUNDS, UNRATE, DCOILWTICO.
For history endpoints, supported range: 1d, 5d, 1mo, 3mo, 6mo, 1y, 2y, 5y, 10y, ytd, max; interval: 1m, 5m, 15m, 30m, 1h, 1d, 1wk, 1mo.
Always show units (USD, %, bps) and freshness (timestamp / cached) when presenting values to the user.
Format large numbers with thousands separators ($1,234,567.89).
Never make investment recommendations. Present data factually and add a brief "this is data, not advice" caveat for non-trivial questions.
When the user asks a comparative or multi-asset question, fan out calls in parallel and merge results client-side.
If a /v1/free/... call fails, retry once with the matching /v1/... path before giving up.

Helper Scripts

A small Python client lives in scripts/:

scripts/finskills_client.py — typed minimal HTTP client (sync + async) covering every endpoint group.
scripts/quote.py — CLI: python scripts/quote.py AAPL TSLA NVDA → live quotes.
scripts/snapshot.py — CLI: python scripts/snapshot.py AAPL → quote + analysts + insiders + news + filings in one report.
scripts/screener.py — CLI: python scripts/screener.py --top-gainers 25 → market mover screening.

All scripts read FINSKILLS_API_KEY from env. Pass --base-url to override.
