Jev API Evidence Fields

The public API reference documents one evaluation route — POST https://api.typesafe.ai/v1/systemone — plus GET /v1/models. This page title is not a separate first-party URL in that reference. Treat the capability as something you implement around the official call.

Put passages, records, and quotes in state (or structured instructions). Answers are typed judgments about that material, not a citation list. This site does not sell, issue, or proxy TypeSafe keys. Authenticate with a credential you already have from the console or a documented gateway.

Jev API Evidence Fields: context

Cookbooks that “check citations” still require you to supply the source span. Jev does not fetch URLs.

Jev API Evidence Fields: inputs

Name evidence fields. Point questions at them with backticks. Filter unused passages (jaggedness + cost).

Jev API Evidence Fields: decision logic

If you need to show “why,” display the state spans you sent plus probabilities — not a generated rationale.

Jev API Evidence Fields: implementation notes

State docs: concepts/state. We will not invent answers.evidence.

FAQ

Is this a documented TypeSafe URL?

No. The public reference lists POST /v1/systemone and GET /v1/models. This title is an application pattern around that contract — not a cloned rival endpoint list.

How should I implement it?

Keep one evaluation POST. Put batching, jobs, search, or policy in your code. Do not invent /v1/batch or similar unless TypeSafe documents it.

Does jev.pro issue keys or OpenAPI?

No. Use official SDKs and docs.typesafe.ai. We do not sell credentials.

What this page does not claim

• Official TypeSafe status, logos, or support.
• That jev.pro sells, issues, or proxies API keys.
• Extra first-party HTTP routes beyond POST /v1/systemone and GET /v1/models unless the API reference lists them.
• Invented latency SLOs, search volume, or unofficial prices. List price and rate limits are vendor claims — confirm on models.
• That a schema-constrained answer is automatically factually correct.
