When send request to permid search API, the system is not stable. Sometimes get HTTP error 504, especially after send several requests. The detailed information {"fault":{"faultstring":"Gateway Timeout","detail":{"errorcode":"messaging.adaptors.http.flow.GatewayTimeout"}}}
I ran it 40 times and it worked fine.
curl -X GET --header "Accept: application/json" "https://api-eit.refinitiv.com/permid/search?access-token=<token>&q=TRI" -v
Please share the request that you are using.
My requests are like this, 'https://api-eit.refinitiv.com/permid/search?format=JSON&entityType=organization&q=International+Business+Machines+Corp'. The API recovers in these days.
