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):
320193or0000320193. - 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.
