get_ticker
Get the issuer behind a ticker
get_ticker is the issuer behind a ticker: a ticker and its exchange, or an ISIN or LEI, returns the issuer, its ISIN, its LEI, its listing and its status — every value with its source page and read date, signed by the node of the listing's market and receipted. Served from the record as read; a value the market's record does not carry says not_on_record. Typed errors: unknown_issuer, ambiguous, not_on_record (per field, per market), invalid_request. Door: https://mcp.getticker.ai/mcp (routes to the owning node); every node door answers it for its own market.
