## Search Instruments

`v1.instruments.search_instruments(InstrumentSearchInstrumentsParams**kwargs)  -> InstrumentSearchInstrumentsResponse`

**get** `/v1/instruments/search`

Search instruments by symbol, alternate identifier, or company name.

The `q` parameter is case-insensitive and supports ticker symbols,
alternate identifiers such as CUSIP, ISIN, OPRA root, and CMS identifiers,
and company names for non-option instruments. Results are ranked by match
quality plus instrument quality signals including log-scaled ADV, listing
status, marginability, easy-to-borrow status, and OTC, restricted, and
liquidation-only penalties. Defaults to the `EQUITY` asset class (common
stocks, preferred shares, ADRs, ETFs, and exchange-traded mutual funds).
Pass `asset_class=OPTION` to search option contracts by symbol or alternate
identifier.

### Parameters
