BATCH CROSSWALK — up to 100 symbols resolved in ONE pass, each returning its current identifiers (CUSIP9, CUSIP8, ISIN, SEDOL, ticker, estimate-vendor ticker), its issuer keys (gvkey, CUSIP6, regulator filer number), which rung matched and its status. This is the endpoint for mapping a whole portfolio or watchlist in a single call rather than N of them. Every symbol comes back with an explicit status — resolved, historical (renamed or delisted; the security and what it trades as now are both returned), ambiguous (shared by more than one current security: the candidates are listed and NO identity is guessed) or unknown (not carried). Symbols beyond the 100 limit come back as explicit over_limit entries, never silently dropped, and the response reports how many of the requested symbols resolved as a number and a percentage (measured 2026-08-02 on a 102-symbol large-cap list: 100 looked up, 99 resolved, 1 historical, 2 over_limit).
