Does the DSS rest api endpoint "/Search/EquitySearch" have any limits? Are there any non production environments that we can connect to in order to test this DSS rest api?

@terence.manuel27, to add to Gareth's answer (thank you Richard for these details):
There are 2 limits you must be aware of (they apply to all API calls you make at a given time, this is not limited to search calls):
- 3000 calls / minute. You cannot submit more than 3000 API calls in a minute.
- 50 concurrent requests. You cannot have more than 50 overlapping (i.e. not yet finished) requests at any given time.
When you reach a processing limit you will receive an HTTP 429 status code. The proper handling of such a response is to wait a little bit and then try again. If you see this status regularly you should reduce your call rate to the servers.
See also the Best Practices and Limits document.

Unfortunately we do not have dedicated non-prod environment for clients to test some of the REST API calls.

Hi Terence,
Just to give a bit of background on DSS access:
While Thomson Reuters does not provide Non-Production DSS accounts, what is standard is for Users to be either issued with:
> a DSS User Id (which is 'Free Trial' tagged/status) and allows Users to test the product, or / then...
> the existing DSS User I (or new DSS User Id) is then Chargeable/Billable (post-testing)
DSS User Ids are usually issued / created by the Sales team via your company's assigned Thomson Reuters Account Manager. (If you do not know who the Thomson Reuters point of contacts are for this please let us know the company this is on behalf of and we can try to look this up for you.)
--------------------------------------------------------------------------------------------------------------------------
Once you have a DSS User Id access the REST API Help Url that will be of help is:
https://hosted.datascopeapi.reuters.com/RestApi.Help/Home/Index (DSS Credential required)
And more specifically to your question of the Search results limits:
https://hosted.datascopeapi.reuters.com/RestApi.Help/Home/KeyMechanisms?ctx=Extractions&tab=0&uid=Paging (DSS Credentials required), so results look to be retrived in page 'blocks', from the API Reference Tree Url:
https://hosted.datascopeapi.reuters.com/RestApi.Help/Context/Operation?ctx=Search&opn=EquitySearch (DSS Credential required) the description is:
"Search for equities (common, preferred, etc.), indices, exchange warrants, equity options, open funds, etc. Note, the paging skip token does not work. The search will return 500 results (page size) by default. If your result set is larger than this, you can increase the page size in the request or narrow your search criteria."
--------------------------------------------------------------------------------------------------------------------------
More generally the Developer. Community Url for DSS REST API will also be useful: https://developers.thomsonreuters.com/datascope-select-dss/datascope-select-rest-api (Developer Community Creditials required)
Best regards,
Gareth
