@hiroko.goto,

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:

• If the extraction took less than 30 seconds I received the data directly.
• If the extraction took longer than 30 seconds it timed out and returned an HTTP status 202, after which I polled the location URL several times until the data was ready, at which point it was delivered.

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.
