The Scrapy Cloud API (often also referred as the Zyte API) is a HTTP API that you can use to control your spiders and consume the scraped data, among other things.
It is the recommended way to consume scraped data from spiders run on Zyte, regardless of whether they're built with Scrapy or Portia. You can use tags to mark jobs consumed and skip them on next reads.
For more information, please refer to the API reference documentation here:
Note: Portia is no longer available for new users. It has been disabled for all the new organisations from August 20, 2018 onward.
