There is no free entry plan, so an agent needs a paid account before its first call. The top plan (Enterprise) is quoted rather than listed, so anything at that volume goes through a person.
Can an agent buy this on its own?
A price is only half the question. The other half is whether software can get from landing on the site to making a paid call without a person, which is what the AgentReady measures under adopt.
For Stoplight, it can create an account itself; the signup flow is one an agent can actually complete.
Against that, a sales call gates access; credentials must be minted by hand in a dashboard. Each of those is a point where an unattended run stops and waits for a human.
That works out to 55/100 on adopt, against 48/100 overall.
