How We Score
The first version combines price transparency, tool compatibility, model coverage, documentation quality, privacy disclosure and reputation signals. We do not claim a service is stable or fastest before hands-on monitoring exists.
What We Do Not Do
We do not sell shared accounts, resell subscriptions, host user API keys or encourage bypassing official platform limits. Provider pages keep risk notes and last-checked dates visible.
