GET/1.0/shims

Lists every shim the key's workspace can see. Required scope: workbench:shims:read (scopes reference).

A shim is a small decision model built in Workbench: one question, its answers, and examples, compiled into a weights file that decides inside your app with @zerowidth/shims-sdk, with no request and no key at runtime. Read the write-up at Labs: Shims.

id is the shim's stable id. Use it with GET /1.0/shims/:id for the answers and with GET /1.0/shims/:id/weights to fetch the published version.

version is the label of the published version and accuracy its held-out accuracy (0–1). Both are null until a version is published in Workbench.
