==== Description
|
|
|
|
You can get statistics for multiple {dfeeds} in a single API request by using a
|
|
comma-separated list of {dfeeds} or a wildcard expression. You can get
|
|
statistics for all {dfeeds} by using `_all`, by specifying `*` as the
|
|
`<feed_id>`, or by omitting the `<feed_id>`.
|
|
|
|
If the {dfeed} is stopped, the only information you receive is the
|
|
`datafeed_id` and the `state`.
|
|
|
|
|
|
==== Path Parameters

|
`feed_id`::
|
|
(string) Identifier for the {dfeed}. It can be a {dfeed} identifier or a
|
|
wildcard expression. If you do not specify one of these options, the API
|
|
returns statistics for all {dfeeds}.
