Ecommerce input contracts with Jev
Catalog copy, reviews, and promo banners need a keep / edit / hold decision before they go live. Recs, search rank, and inventory still own merchandising math. Jev judges language against your policy excerpt. It does not set prices or personalize a homepage.
This unofficial page is the input contracts slice of the ecommerce merchandising decisions pack. Intent: apply the Jev (TypeSafe System One) decision model to ecommerce merchandising decisions input contracts. Primary search language: Ecommerce Jev input contracts. Confirm patterns on docs.typesafe.ai. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.
Independent angle (cover ≠ clone): Claim/policy + merchandising action on catalog text — not a clone of a personalization-engine sitemap or recs API landing page.
Ecommerce use-case context
An input contract is the allow-list of fields you will ever POST for ecommerce merchandising decisions. It is a decision contract for the product copy or promo text: if a field is not named in instructions, it should not be in state. That is how you beat noisy “dump the object” integrations — the rival-intent failure mode — without cloning anyone’s IA.
Hub: Use cases. Compare, when the other tool is the real job: ecommerce personalization.
Input Contracts inputs
Documented System One inputs: state (string, object, or array of text) and a questions map. English is the primary training language. Images, audio, and video are not accepted.
Allow for ecommerce merchandising decisions:
{
"item": { "id": "sku-88", "title": "Lose 10kg tea", "bullets": "Guaranteed results in 7 days." },
"policy": { "health": "No absolute health outcomes.", "stock": "Do not claim in-stock if inventory_flag is false." },
"flags": { "inventory_flag": true, "locale": "en" }
}Bind paths: item.title, item.bullets, policy.health, flags.inventory_flag.
Refuse at the wrapper (do not send):
- product photos (not accepted)
- clickstream / affinity graphs
- the whole catalog as one Choice
TypeSafe’s published list price for jev-1.13 is $0.042 per million input tokens (vendor claim — confirm on the models page); output tokens are free on that same page. Unused distractors still bill as input.
Decision signals and actions
The contract exists so each primitive stays atomic:
| Id | Type | Job |
|---|---|---|
action |
Choice | publish / edit / hold_legal / other |
claim_risk |
Score | plain description → aggressive outcome claim |
policy_ok |
Noul | Copy consistent with policy.* given flags.inventory_flag? |
If a new CRM field appears, either add a question that names it or drop it. Do not “just include it.” Do not treat a Noul of 0.5 as a “medium” ecommerce merchandising decisions score — it means yes and no are equally likely. Conjunctions stay in your code.
Guardrails and escalation
Contracts are a guardrail: missing required text → do not call Jev (or ask a Noul “is enough information present?”). That is cheaper than a confident wrong action. TypeSafe’s confidence-gated examples use a lower bar for recoverable reads than for irreversible actions. Those numbers are illustrations. For ecommerce merchandising decisions, treat publish as the high bar (publishing customer-visible copy or a live promo). Tune on labels — see offline evaluation.
Evaluation and rollout notes
Version the contract (field list + criteria git SHA) next to the pinned model. Replay publish/hold gold from merch+legal, plus claim_risk gold when either changes. Pin jev-1.13.0 (the versioned id) after you fit thresholds. jev-latest and the marketing line jev-1.13 can move. Log the response model. TypeSafe’s published list price for jev-1.13 is $0.042 per million input tokens (vendor claim — confirm on the models page); output tokens are free on that same page. Unused distractors still bill as input.
Official Python and JavaScript SDKs read TYPESAFE_API_KEY and retry documented 429/529. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.
