Alpha Vantage — Stock and Market Data

Alpha Vantage's REST API for stock prices, fundamentals, technical indicators, forex, crypto, and economic indicators. ~20+ years of historical equities data, real-time-ish quotes (15-minute delayed on free tier), and structured fundamental data parsed from SEC filings.

Part of Pipeworx — an MCP gateway connecting AI agents to 1679+ live data sources.

Why this matters for AI agents

Where SEC EDGAR gives you raw filings, Alpha Vantage gives you cleaned-up structured data ready for analysis: income statements, balance sheets, cash flow, key ratios, recent earnings, technical indicators. For real-time-ish quotes during market hours, this is the source.

Common flows:

• Quote. "Where's AAPL trading?" → av_quote({symbol: "AAPL"}) → latest price, change, volume.
• Income statement. "Apple's last 4 quarters of revenue/income." → avincomestatement({symbol: "AAPL"}).
• Earnings. "When does NVDA report next?" → av_earnings({symbol: "NVDA"}).
• Daily price history. "AAPL 1-year history." → av_daily({symbol: "AAPL"}).

Used by the fintechcompanydeep_dive compound for the quote + income statement layer alongside SEC EDGAR.

Auth — bring your own PAID key (Pipeworx fronts none)

This pack is BYO-only as of 2026-09-02 (Bruce's ruling on fleet #1117). Pipeworx does not supply a key: the gateway entry no longer names PLATFORMALPHAVANTAGEKEY, so _apiKey is whatever you pass and nothing else. Call it with no key and you get a refusal that says the pack requires an API key and names two working substitutes — no upstream call is spent producing it.

A FREE Alpha Vantage key will not work here, whoever it belongs to. Alpha Vantage meters its free tier by SOURCE IP and never validates the key at all — measured 2026-09-02 on three real keys plus the invented string ZZZZINVALIDKEY99, which drew the same "25 requests per day" refusal from our gateway that a real key did, and returned real IBM data from a laptop in the same minute (fleet #1070; the full measurement is in the header of src/index.ts). Because the address the call leaves from is what is spent, your free key is refused through the gateway for exactly the reason ours was. That also means a laptop test proves nothing about this pack: any string "works" from an IP with budget left.

What does work: a PAID key. Premium ($50–250/mo) is the one thing Alpha Vantage actually authenticates — its premium endpoints refuse a free key by name. Untested from here, since we do not hold one, so treat it as an inference rather than a measurement. Pass it via _apiKey.

If you have no paid key, use the substitutes the refusal names, both of which answer these questions today:

sheets and cash flow, keyless, no daily cap. Covers everything avoverview / avincomestatement / avbalancesheet / avearnings do for US filers.

• getcompanyfinancials (sec-xbrl pack) — US income statements, balance

Covers av_quote, and non-US symbols.

• finnhub — real-time quotes, free key, 60 calls/min and no daily cap.

The "demo" key: Alpha Vantage advertises demo as a no-signup key, but it returns errors for most calls, and through the gateway it hits the same IP meter as any other free key. The pack refuses it explicitly.

Update cadence

• Quotes: real-time on paid tiers, 15-minute delayed on free, market hours only
• Daily / weekly / monthly history: end-of-day, refreshes after market close
• Fundamentals: refreshes within ~24h of new SEC filings

Pipeworx caches with TTLs aligned to these.
