COMPARISON

Filingrail vs Alpha Vantage

Alpha Vantage is a popular market-data API — stock time series, technical indicators, forex, crypto, and some derived fundamentals. Filingrail is SEC-EDGAR-only. They barely overlap, so this is less a head-to-head than a “which job are you doing” guide.

Plain facts in both columns. Where a value depends on the other provider’s current plan, we say so rather than pin a number that might drift — verify the live figures on their own pricing page before you commit.

AT A GLANCE

The short version

Alpha Vantage is market data — prices, indicators, forex, crypto — with derived fundamentals. It does not offer SEC filing documents, Form 4 insider trades, 8-K feeds, or 13F holdings, and its fundamentals aren't tied to a specific EDGAR filing. Filingrail is the opposite: SEC filings only, with a source-filing URL on every record. If you need charts and quotes, use Alpha Vantage; if you need filings, use Filingrail. Many workflows use both.

HONEST CALL

When each one is the better fit

Pick Filingrail when…

  • You need actual SEC filings — Form 4 insider trades, 8-K events, 13F holdings — which Alpha Vantage doesn't provide.
  • You need filing-level traceability (source_filing_url) for audit or citation.
  • You want XBRL-normalized financials tied to the underlying 10-K/10-Q, not just derived fundamentals.
  • You want a first-party MCP server for agent use.

Pick Alpha Vantage when…

  • You need stock time series, technical indicators, forex, or crypto — Filingrail has none of these.
  • You need real-time market data and options data.
  • You want the widely-tutorialed developer experience and CSV output.
  • You're doing quant/charting work rather than filings analysis.

FAQ

Common questions

Still deciding? Email support@hudsonenterprisesllc.com — same business day response.

Is Filingrail a drop-in replacement for Alpha Vantage?
No — they solve different problems. Alpha Vantage is market data and technical indicators; Filingrail is SEC filings. They barely overlap (only loosely on company financials, and even there the sourcing differs).
How do the prices compare?
Filingrail: free 50/day, then $9/mo (Pro), $49/mo (Ultra), $199/mo (Mega). Alpha Vantage: free 25/day, then $49.99/mo up to $249.99/mo. Filingrail’s paid entry ($9) is much lower; Alpha Vantage’s floor paid tier is $49.99.
Does Filingrail cover the same data?
Mostly no. Alpha Vantage focuses on prices, indicators, forex, and crypto, which Filingrail does not offer. Filingrail focuses on SEC EDGAR (filings, XBRL financials, Form 4, 8-K, 13F), which Alpha Vantage largely does not offer.
What does source-traceability mean?
Filingrail returns a link to the source filing with the data — filing_url on each record, or meta.source_filing_url and meta.source_filing_date on company financials — tying each figure to the exact SEC filing. Alpha Vantage’s fundamentals are not linked to a specific filing.
Who handles billing?
Filingrail is billed by RapidAPI (merchant of record). Alpha Vantage bills you directly on your own account.
