API updates

The v1 surface is alpha. Schema names and types are stable; extraction quality improves continuously.

Deprecation policy

Breaking changes get 90 days' notice via the Sunset and Deprecation response headers (RFC 8594) and an entry here. Additive changes (new fields, new endpoints) ship without notice and never break a conforming client.

2026-09 — KPI tools carry the company's layout judgment

• Added (additive): list_company_kpis returns rows in the company's judged order and, once judged, a top-level headline list plus per-row tier, family, polarity and stale_quarters; get_kpi_series.metric carries the same, and a cited point may carry approximate: true. Duplicate labels for one measure are now hidden. See What the judgment fields mean.

2026-09 — fundamentals endpoint retired

• Removed: GET /v1/companies/{symbol}/fundamentals and the list_fundamentals MCP tool. The layer behind them was a narrow extracted snapshot that duplicated the KPI dataset at lower coverage and freshness. Use list_company_kpis / get_kpi_series for company-native operating metrics and get_financial_statements (MCP) for reported financials.
