HOW TO QUERY SAFELY
先用 catalog 确认当前契约;可按 catalog 中列出的 filters 进一步缩小范围;单页最多 5000 行,该表不提供稳定 cursor,结果过大时必须缩小标的、日期或其他筛选。
MACHINE CONTRACT
updated_at, entity_id, alias—canonical_final_activealias→ alias · stringcik→ cik · stringentity_id→ entity_id · stringentity_type→ entity_type · stringmarket→ market · stringsource→ source · stringsymbol→ symbol · stringuei→ uei · stringPOINT IN TIME
该资产没有 PIT 契约。普通 rows 端点仍按当前公开读模式返回数据;不要把它表述成历史时点快照。
COPY-READY CALLS
