Server instructions

QuarterCharts serves grounded SEC EDGAR XBRL financial data for US-listed companies, with citation provenance on every value. MANDATORY FIRST HOP — call these BEFORE any data tool (get_chart / get_metric / get_segments / compare_tickers / etc.): 1. qc.resolve_entity — resolve the company identifier (ticker, name, former name, CIK) to the canonical SEC registrant. Skipping this drops retrieval accuracy from 93% to 77% (wrong-entity / dual-class / former-name errors). 2. qc.resolve_period — resolve the period spec ('FY2026 Q4', a fiscal year, or a calendar date) to exactly ONE dated fiscal period. Fiscal-vs-calendar confusion (non-December year-ends like Apple's September FYE or retailers' January FYE) is 63% of all agent financial-retrieval errors; this single call removes it. The response returns BOTH fiscal_label and calendar_label plus period_start / period_end so you can verify you got the intended period, and FAILS LOUD (listing the available periods) instead of silently returning the wrong year. Only after resolving the entity AND the period should you call a data tool, passing the resolved ticker + the verified fiscal period. Both resolve tools are open to every tier (no Pro gate).
