Jukka,
Somewhat counter-intuitively, you can use
"https://api.digitransit.fi/routing/v1/routers/hsl/isochrone?fromPlace=60.168,24.938&mode=WALK,TRANSIT&date=2019-11-01&time=08:00:00&maxWalkDistance=500&cutoffSec=1800&cutoffSec=3600";
as a filename when using the File source type. This is due to GeoJSON
driver having a particular logic when passed a http[s]:// filename to
ingest it fully in memory.

Hi,
This command gives a result with ogrinfo:
ogrinfo
/vsicurl_streaming/"https://api.digitransit.fi/routing/v1/routers/hsl/isochrone?fromPlace=60.168,24.938&mode=WALK,TRANSIT&date=2019-11-01&time=08:00:00&maxWalkDistance=500&cutoffSec=1800&cutoffSec=3600";

If I try to use the URI part with QGIS with Add layer – Vector –
Protocol – HTTP/HTTPS/FTP then QGIS seems to add automatically
/vsicurl/ into the service request. With this service /vsicurl/ does
not work but /vsicurl_streaming/ works. It there any way to force QGIS
to use the streaming mode?
The debugging tools do not seem to log the network traffic from the
“read from protocol” requests. Is that a right observation?
