|---|---|---|
| No match | "No matches." | Shorter substring, local-language name, or company_search |

Notes
- Up to five matches, prefix hits first, then by name length. Symbols carry their market suffix: US bare, A-shares .SH / .SZ, Japan .T.
- Call this first whenever the question names a company rather than a symbol.
Endpoint, client setup and billing are common to all tools. For details, please refer to MCP server.
