Use after search_companies to confirm a company's identity and financials availability; use get_financials instead for the statements themselves. Read-only; no API key. Provide `ticker` or `cik`; if both are given, `cik` takes precedence. Any listed ticker for a company resolves to that company, not just its primary ticker.",

Use for period-by-period statements; use get_metric_history instead for one concept's long time series, and list_financial_concepts to see which concepts exist. Read-only; no API key. Values are cleaned: when a period was reported more than once the latest filing wins, fiscal periods are verified, and values computed from reported components carry derived:true plus a 'derived:' source tag — this includes Q4 figures, derived as fiscal year minus Q1–Q3 because quarterly filings never contain a filed Q4 (a restated FY or quarter changes the derived value, so derived Q4 can differ from a Q4 filed later). Responses also carry a staleness flag when SEC submissions show a newer filing than the stored facts, and predecessor companies when a ticker moved between filers (e.g. a reorg), whose history is included in the periods. Every value carries per-value provenance (form, filed date, accession number). Identify the company by ticker or CIK (CIK wins if both are given). Coverage loads progressively — roughly 25 more companies refreshed per day, priority tiers first — so a valid company can legitimately return 'no financials stored yet'.",
