SDKs

Clients talk to a running Kev server (POST /v1/systemone). Published packages:

npm install @kev-ai/sdk
pip install kev

TypeScript

import { Choice, KevClient, Noul, Score } from "@kev-ai/sdk";

const client = new KevClient({ baseUrl: "http://127.0.0.1:3000" });

const res = await client.systemOne({
  state: "Package stuck in transit for a week. Tracking frozen.",
  questions: {
    topic: Choice("Which team?", {
      billing: "charges",
      shipping: "delivery / tracking",
      technical: "bugs",
    }),
    severity: Score("How urgent?", [
      "can wait",
      "this week",
      "today",
      "right now",
    ]),
    escalate: Noul("Page a human?"),
  },
});

if (res.answers.escalate.noul > 0.7) routeToHuman();
else assign(res.answers.topic.choice);

Adapters (same package)

import { createLangChainKevTool } from "@kev-ai/sdk/langchain";
import { createLlamaIndexKevTool } from "@kev-ai/sdk/llamaindex";

Python

from kev import KevClient, Choice, Noul

client = KevClient(base_url="http://127.0.0.1:3000")
res = client.system_one(
    state="Charged twice. Furious.",
    questions={
        "topic": Choice("Which team?", {
            "billing": "charges",
            "technical": "bugs",
        }),
        "escalate": Noul("Escalate now?"),
    },
)
print(res.answers["topic"].choice, res.answers["escalate"].noul)
