n8n-nodes-typesafe-jev
Dependency-free n8n node for TypeSafe Jev with choice, yes/no and score questions and npm provenance-signed releases.
Overview
@n3ndor/n8n-nodes-typesafe-jev is an unofficial community node for TypeSafe Jev. In one execution it can ask several independent questions about the same state and return calibrated probabilities for classification, routing, verification and scoring. It calls the API through n8n's own HTTP helper rather than a vendor SDK, so it has no runtime dependencies, which is a requirement for n8n verification.
State can be plain text, a JSON object or array, defaulting to the whole incoming item; questions are built field by field or supplied as JSON generated upstream. Output can be appended to the item, returned alone, or reduced to answers, with an optional Simplify mode. The model dropdown loads from your account, and releases from 0.4.0 carry npm provenance attestations that can be checked with npm audit signatures.

| Type | Question | Answers |

Frequently asked questions
Why does having no dependencies matter?
n8n verification does not permit runtime dependencies, and it keeps the install small.
Can I verify the package?
Releases from 0.4.0 have npm provenance; check with npm audit signatures.
Is it official?
No, it is community-maintained and not affiliated with TypeSafe.
