Gotchas - check before you buy

medium

Free tier hard-caps at 50 calls/day; paid limits and overage pricing unclear before you commit

is parked for sale at $799 — buyers may land on a lookalike domain

Multiple templated LinkedIn posts tout Filingrail; treat them as promotion, not user feedback

low

Only self-published pricing and comparison pages exist; the vendor's 'vs FMP' page is marketing, not neutral analysis

Pros and cons

Pros

  • Free tier: 50 calls/day, no credit card required
  • Runs inside Claude, Cursor and other MCP clients
  • Hosted: no SEC EDGAR parser to maintain yourself
  • Covers financials, XBRL, Form 4 insider trades, 8-K events
  • Simple API-key auth; keep the key server-side

Cons

  • Solo-developer product; bus-factor and longevity risk
  • Narrow scope versus Financial Modeling Prep's broader data
  • Visibility is self-promotion and directories, not user reviews
  • Rides on RapidAPI for billing, limits, and availability
  • Main site is a subdomain; matching .xyz domain is for sale
