Jev 1.13

Incognito

typesafe/jev-1.13

Jev is a structured decision model from TypeSafe, and the first of its System One models. System One models make fast, structured decisions for software, returning a typed choice rather than free-form text. It is suited for routing, classification, and other decision points inside an application where a fast, predictable answer matters more than generated prose.

Privacy & execution

This Incognito model runs on a partner provider’s infrastructure. NEAR AI routes requests using shared provider credentials, so your NEAR AI account credentials are not forwarded.

Your prompts are processed by the provider under its terms and privacy policy. HTTPS protects data in transit. Model TEE attestation and client-to-model end-to-end encryption are not provided for this model. Where available, Gateway signatures verify the request and response handled by the Gateway.

Verification documentation

Make your first request

Call /v1/systemone over HTTPS.

Get an API key and replace the API key placeholder below.

Submit context in state and typed questions in questions. Questions support probability (noul), choice, and score answers. The response contains answers and token usage. Streaming and the chat playground are unavailable for decision models.

curl --fail-with-body -D - "https://cloud-api.near.ai/v1/systemone" \
  -H "Authorization: Bearer <YOUR-NEAR-AI-CLOUD-API-KEY>" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "typesafe/jev-1.13",
  "state": "I was charged twice. Please help.",
  "questions": {
    "billing": {
      "type": "noul",
      "instructions": "Is this about billing?"
    }
  }
}'

Copy the X-Generation-Id response header, then retrieve its receipt using the same API key:

GENERATION_ID="<X-Generation-Id response header>"
curl --fail-with-body "https://cloud-api.near.ai/v1/signature/${GENERATION_ID}?signing_algo=ed25519" \
  -H "Authorization: Bearer <YOUR-NEAR-AI-CLOUD-API-KEY>"

Check signature_kind: gateway is a Gateway receipt, not proof of TEE execution; provider_tee identifies a provider TEE receipt. Fetching a receipt alone does not verify it. Verification checks the signature and hashes of the exact request and response bytes. System One does not support end-to-end encryption.

Example

const response = await fetch("https://cloud-api.near.ai/v1/systemone", {
  method: "POST",
  headers: {
    Authorization: "Bearer <YOUR-NEAR-AI-CLOUD-API-KEY>",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
  "model": "typesafe/jev-1.13",
  "state": "I was charged twice. Please help.",
  "questions": {
    "billing": {
      "type": "noul",
      "instructions": "Is this about billing?"
    }
  }
}),
});
if (!response.ok) throw new Error(await response.text());
console.log(await response.json());
console.log("X-Generation-Id:", response.headers.get("X-Generation-Id"));
