Fiscal.ai

Pros

  • + Click-through audit to filing: on Max, every Copilot figure links to the exact filing page it came from — I traced several figures and the links landed on the right source paragraph
  • + Same database is available as REST API, webhooks and an MCP server (api.fiscal.ai/mcp) with an official Claude connector, so research data flows into your AI tools
  • + Free tier includes ten years of annual financials — enough for a real trend check before paying
  • + Copilot does cross-document analysis on Pro (10-K vs earnings-call tone), which is more useful than single-document summaries
  • + $79/month Max undercuts mid-market terminals dramatically while keeping standardized and as-reported figures side by side

Cons

  • - No real-time quotes anywhere, and no options or futures — delayed fundamentals data only
  • - Financial-data export is Max-only and stops at the US, Canada, ADRs, the UK and the EU despite 100K+ stock coverage
  • - API transcript and news history is months deep, not years (news starts late April 2026), which limits backtesting
  • - The API/MCP subscription publishes no price and bills annually, so infrastructure cost needs a sales call
  • - Company is young (FinChat launched 2023, $10M Series A June 2025) — thin operating history compared with incumbent data vendors

Mercury

Pros

  • + Base plan is genuinely $0/month with no minimums or overdraft fees, and the free surface covers checking, cards, invoicing and bill pay
  • + Insights — live dashboards, ad-hoc financial questions, spend notifications — is included free on every plan per mercury.com/insights
  • + Command executes natural-language instructions across the account stack but only with explicit per-action approval and a traceable record
  • + Up to $5M FDIC insurance through partner banks and sweep networks, per the plan comparison
  • + Free API, MCP server and CLI let you drive Mercury from your own agent tooling

Cons

  • - US-only for business banking, cards and treasury — non-US entities are excluded
  • - Treasury requires a $250K Mercury balance to unlock, locking out early-stage startups
  • - AI features only see Mercury data; no connection to external revenue or payroll systems unless routed through Mercury
  • - Enriched NetSuite automations and $0 ACH debit invoicing sit behind the $299/month Pro plan
  • - 1099 filings cost $5 per filing on the free plan, and Books/Payroll are add-ons whose fee waivers end 31 December 2026
