JSR pricing
JSR does not publish machine-readable pricing and has a free tier, with self-serve signup.
Last checked 2026-08-25. Verify on the vendor's own page before you commit spend.
No structured plans recorded. JSR may quote on request, which means an agent cannot work out the cost of a call before making it.
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 JSR, it can create an account itself.
Against that, a sales call gates access; the signup flow assumes a human at a browser; 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 60/100 on adopt, against 50/100 overall.
