Attested instrument-identity enrichment for AI agents: map a ticker, ISIN, CUSIP, SEDOL, FIGI, or instrument name to canonical FIGI records (name, security type, market sector, exchange) via Bloomberg open symbology, with provenance (source, retrieval time) attached to every answer. Built for agents that must know WHICH security a claim, order, or document is about before acting on it.
