Quick setup examples
Node.js Quickstart
Call the Unison brain from Node.js using the built-in fetch API — no extra dependencies required.
Node 18+ ships with fetch globally, so no extra HTTP library is needed. For a typed, higher-level client consider the official SDK instead: TypeScript SDK.
Prerequisites
export UNISON_TOKEN=usk_live_...Node 18 or later (for native fetch).
Recall — fetch prompt-ready context
const BASE = "https://brain.unisonlabs.ai";
const headers = {
Authorization: `Bearer ${process.env.UNISON_TOKEN}`,
};
const params = new URLSearchParams({ q: "payment service architecture", k: "5", mode: "auto" });
const res = await fetch(`${BASE}/v1/brain/context?${params}`, { headers });
const data = await res.json();
const memory = data.weakEvidence ? "" : data.contextMd;
// Prepend `memory` to your system prompt before calling the LLMPersist — write memory to the brain
const res = await fetch(`${BASE}/v1/brain/ingest`, {
method: "POST",
headers: { ...headers, "Content-Type": "application/json" },
body: JSON.stringify({
items: [
{
type: "conversation",
turns: [
{ role: "user", content: "What queue library should we use?" },
{ role: "assistant", content: "Switched to pgmq — simpler ops than Redis." },
],
sourceRef: "session-1",
visibility: "private",
},
],
}),
});
const { items } = await res.json();
console.log("jobId:", items[0].jobId);The returned jobId tracks async indexing. New memories surface in recall queries within seconds.
