get_as_of
Get the issuer record as of a date
get_as_of is the issuer record as it stood on a date: an issuer by ticker, ISIN or LEI plus a date returns the signed record of that day — every field with its source and read date, the sealed disclosure lines of the market-year up to that date — signed by the node of the issuer's market and receipted, so a backtest can show what it read and when. Nothing is restated and nothing is filled backwards: before the record existed the answer says before_record; in a market-year not yet sealed it says not_sealed and names the earliest sealed date. Served from the Replay store under Data Vintage (sealed market-years, 2021 forward); typed errors unknown_issuer, before_record, not_sealed, not_found; every answer carries the node signature (kid) and its RCO-10060 receipt (verify_receipt at https://mcp.rco-records.ai/mcp).
