Looks like there is no legal way to pause/continue crawling with Scrapyd, as it was with Scrapy itself (scrapy crawl spider -s JOBDIR=jobdir/spider-1). The only resolution i've found was here:

but i haven't understand the idea.
So is it possible to pause/continue job with Scrapyd?
Thanks for your time
The idea is following:
When you run your spider from cmd you can paste additional an argument, for example: scrapy crawl myspider -s JOBDIR=crawls/somespider-1
When you use Scrapyd in endpoint schedule.json you can also paste some settings. If you are using scrapyd-client this will look like this:
s = {'JOBDIR': 'crawls/somespider-1'}
job = api.schedule(project_name, spider_name, settings=s)
After it, you can cancel a job. Next time, when you will run the same job - scrapyd resume previous work
