Symbology
Symbols follow the grammar SYMBOL[:MARKET]. MARKET is a market code
(US, IN, GB, AU, …). A bare AAPL means AAPL:US.
Responses always echo the fully-qualified form plus every identifier we hold:
"company": { "symbol": "AAPL:US", "ticker": "AAPL", "market": "US", "name": "Apple Inc.", "cik": "0000320193", "isin": "US0378331005", "figi": "BBG000B9XRY4", "issuer_id": 1234}Identifier filters
List endpoints accept these repeatable filters:
tickers, ciks, isins, figis, issuer_ids, markets.

model is already market-agnostic, so no schema change is needed to add them.
