Get Instruments

Interface Description

• Function description: Query the underlying information according to the security symbol list and security type.

• Request URL: /instrument/list

• Request method: The interface provides HTTP and gRPC two protocols for the query. There is no difference between the data queried by the HTTP and gRPC interfaces. The HTTP interface only needs to obtain data through ordinary GET requests, and the gRPC needs to use the Webull SDK to establish a gRPC connection before it can be used.

• Frequency limit: The calling frequency of each AppId is limited to 60 times per minute.

Request Parameters

Request Example

HTTP

Python

from webullsdkcore.client import ApiClient
from webullsdkcore.common.region import Region

api_client = ApiClient(your_app_key, your_app_secret, Region.HK.value)
api = API(api_client)
response = api.instrument.get_instrument(symbols, category)
if response.status_code == 200:
    instruments = response.json()

Java

HttpApiConfig apiConfig = HttpApiConfig.builder()
        .appKey(Env.APP_KEY)
        .appSecret(Env.APP_SECRET)
        .regionId(Region.hk.name())
        .build();
try (QuotesApiClient quotesApiClient = new HttpQuotesApiClient(apiConfig)) {
    List<Instrument> instruments = quotesApiClient.getInstruments(symbols, category);
}

gRPC

Python

api = API(grpc_client)
response = api.instrument.get_instrument(symbols, category)
if response.status_code == 200:
    instruments = response.json()

Java
