On-demand access
AIsa offers on-demand access with no subscription package
02
Make calls
Usage is generated only when you make real API calls.
03
Pay by usage
Billing is based on your actual call volume.
Two routes, very different cost pressure
AIsa turns subscription cost into usage cost
×
Similarweb official: buy first, then use
× Review plans, contact sales, then confirm API access
× Budget and volume need to be estimated upfront
× Package size and term are decided before activation
× If usage drops, committed package cost can still remain
× Small trials may be slowed down by the buying process
× Occasional queries and short projects have less cost flexibility
VS
✓
