Implementation Reference
- server.py:886-914 (handler)The asynchronous function that executes the lookup_identifier tool. It maps the identifier_type to the appropriate Financial Modeling Prep API endpoint, performs an HTTP GET request with the query, and returns the JSON response or an error message.
