Margin of Insight — Equity Research

Connects Claude to equity research reports for 752 US-listed companies, expanding toward the Russell 3000. Exposes six tools: get_company_primer (free, no auth), get_fundamental_analysis ($1), get_investment_memo ($2), plus list_coverage, search_research, and request_coverage for tickers not yet in the system. Uses Stripe Link Shared Payment Tokens for per-call billing instead of subscriptions or API keys. Each report follows a 21-step analyst framework covering business model, financials, competitive positioning, risks, and valuation scenarios. Reach for this when you need structured investment research without spinning up your own SEC filing parser or burning $7-9 in LLM calls per company. Response includes freshness timestamps so you know how stale the data is.
