The TypeSafe Playground
TypeSafe’s quick start begins in the Playground, not in curl:
- Open the Playground and log in.
- Paste text as the state (their example is a failing Stripe integration).
- Add a Noul such as “Does this message express urgency?”
- Mix Noul, Choice, and Score in one call.
Docs pages that embed examples often link “Try it in the Playground” via console.typesafe.ai/decode#share/.... That is their share format, not something jev.pro hosts.
Use the Playground to settle wording and criteria. Then copy the JSON into POST /v1/systemone or an SDK. Do not treat playground latency as a published SLA — TypeSafe’s own speed notes were measured from West Coast laptops for their evals.
jev.pro does not embed a proxy playground and will not ask for your console cookie.
