Time series for one metric across fiscal periods. Returns newest-first rows with fiscal_year + fiscal_period labels — AUTHORITATIVE for period-specific questions ("Q2 FY2025?"). The period_end calendar date is NOT the fiscal label, especially for non-December FYE companies (AAPL FY ends Sep; CRM FY ends Jan; ORCL FY ends May).

Each row with an SEC accession is cited back to the source filing via the MetricDuck viewer.

⚠ CONSOLIDATED ONLY — there is no segment/geography/product breakdown here, and no parameter adds one: the metrics layer sums those axes away, so per-member values are never stored. For a BY-SEGMENT series use get_xbrl_facts(ticker, search="<segment name> revenue", period_history=true) (as-filed dimensional facts) or get_filing_section(ticker, "table_segment_reporting") (the schedule, 3 fiscal years per 10-K).

Use Cases:

Also serves NON-XBRL operating KPIs (LLM-extracted from 10-K/10-Q MD&A + earnings releases), available QUARTERLY and ANNUAL (FY) — coverage varies by KPI. Spans banking (net_interest_margin, common_equity_tier_1_capital_ratio), insurance (combined_ratio), SaaS (arr, remaining_performance_obligations), retail/marketplace (store_count, same_store_sales, gross_booking_value, take_rate), lodging/REIT (revpar, occupancy_rate), airlines (passenger_load_factor, prasm, casm), energy (oil_production), workforce (headcount), and more — see the metric_id parameter for the common ids. Matching is strict (lowercase, exact spelling) and an unknown id returns the full served catalog, so guessing a canonical name is cheap. Financial-sector tickers (banks, insurers) often NULL on COGS-based metrics (gross_margin, gross_profit) — use sector-appropriate alternatives where available.

Price-derived multiples here (pe_ratio, ev_ebitda, pb_ratio…) use the PERIOD-END close; for a price on a SPECIFIC date use get_stock_price. To assemble a CUSTOM multiple (e.g. EV including operating leases) combine get_stock_price (price leg) with get_metric_history primitives: oper_lease_liabs, ttl_debt, cash_st_invs, ttl_equity, shares_basic.

**Latest fiscal year during earnings season:** full-year results post in an earnings 8-K weeks before the 10-K, which is what populates this structured FY series. If you query the latest FY inside that gap, the series ends one year early — this tool then appends a pointer to the earnings 8-K; follow it (get_filing_section "earnings_income_statement") rather than concluding the year is unavailable.

Adjacent tools: get_company_overview for a single-period snapshot across many metrics; get_financials for full statements (all line items) across multiple periods; get_stock_price for daily share prices and period returns.

Input schema

PropertyTypeRequiredDescription
tickerstringyesCompany ticker symbol (e.g., 'AAPL'). Must be exact.
metric_idstringyesExact metric id (lowercase + underscores). Common XBRL financials: gross_margin, oper_margin, net_margin, ebitda_margin, roe, roa, roic, pe_ratio, ev_ebitda, ev_sales, fcf_yield, pb_ratio, current_ratio, debt_to_equity, interest_coverage, revenues, net_income, ebitda, fcf, net_cf_ops, capex, dividends_per_share, dividends_paid, dividend_yield, dividend_payout_ratio, fcf_payout_ratio, dividend_coverage. Operating KPIs (non-XBRL, quarterly AND annual), most-covered first: net_interest_margin, return_on_average_assets, return_on_average_equity, nonperforming_assets_to_total_assets, nonperforming_loans_to_total_loans, allowance_for_credit_losses_to_total_loans, loan_to_deposit_ratio, net_charge_offs_to_average_loans, common_equity_tier_1_capital_ratio, tier_1_leverage_ratio, tier_1_capital_ratio, total_capital_ratio, return_on_average_tangible_common_equity, net_leverage_ratio, nonperforming_loan_ratio, liquidity_coverage_ratio, net_stable_funding_ratio, combined_ratio, loss_ratio, expense_ratio, policies_in_force, arr, recurring_revenue, remaining_performance_obligations, organic_revenue_growth, cancellation_rate, subscribers, arpu, store_count, same_store_sales. Both lists are non-exhaustive — try a canonical name even if unlisted; a miss returns the full served catalog and steers.
period_typestringnoQ = quarterly, FY = fiscal year, TTM = trailing 12 months.
windowintegernoMax observations returned, newest first. Default 20, max 40.
vantage_datestringnoAs-of vantage (YYYY-MM-DD): restrict the series to periods whose ORIGINAL filing was published on or before this date, and cite the filing that was current then. Omit for the latest. IMPORTANT — this bounds period EXISTENCE and the CITATION; it does NOT reconstruct the value as it stood on that date. If a later filing restated a period, the restated value is what is served, and the response carries an explicit LOOK-AHEAD warning naming the affected periods. For a true as-originally-filed series use get_xbrl_facts with period_history=true.
