I can set asynchronous response (to repeat price extractions with tokens after time out setting) for DSS EoD Pricing extraction, however, I could not do so for DSS Intraday Pricing. Is this how the feed works? If it is supported please advsie how to d this.
I don't fully understand your query, but as a first element of answer I can tell you that the asynchronous mechanism (described in detail here) applies similarly to all data extractions, it does not behave differently for EoD or Intraday.
To double check this I just made a test with an Intraday request for several chains, and the async method worked as expected:
Also note that a token is valid 24 hours; this is entirely independent of the async mechanism.
If this information does not suffice, please explain the workflow you are using, and post the EoD and Intraday extraction requests with all the details (including headers), so that we can investigate.
