AI-agent-ready: every numeric value ships with citation provenance (SEC filing URL + XBRL tag + period + accession number) so downstream LLM outputs can be audited back to source. Tools cover income statement, cash flow, balance sheet, 16+ derived metrics (P/E, P/S, ROIC, Graham Number, Net Buyback Yield), Sankey income-to-net flows, ticker search, and chart-explanation natural language. Anonymous callers gated to the per-country free-tier ticker allow-list (7 popular US tickers); authenticated bearer-token callers access the full universe per their plan tier (Pro+ for full US, Premium for international markets, Business for webhooks + bulk).","auth":{"type":"user_http","authorization_type":"bearer"},"api":{"type":"mcp","url":"https://api.quartercharts.com/mcp"},"logo_url":"https://us.quartercharts.com/qc-logo.png","contact_email":"info@quartercharts.com","legal_info_url":"https://us.quartercharts.com/terms"}
