Prune cache.default in worker

I’m working on a custom caching solution using workers. During development it’d be useful to fully prune cache.default.

At first it seemed the API call to<zone_id>/purge_cache would be the solution. However, I cannot find the zone_id.

Search results suggest “scrolling down on your site’s page”. But I do not have a site, only workers.

So how would one go about pruning cache.default with only workers?

Many thanks.

You can’t purge the cache from, only cache in zones.
