Skip to main content
MemoClaw ships an official TypeScript SDK inside the memoclaw package. The same package also contains the CLI, so you get both programmatic access and terminal commands from a single install. Use it anywhere Node.js 18+, Bun, or modern Edge runtimes run.
Prefer a no-code setup for OpenClaw agents? Install memoclaw-hooks alongside the SDK so your agent auto-stores and recalls memories during each session.

​
Installation

npm install memoclaw
# or
pnpm add memoclaw
# or
yarn add memoclaw

​
Authentication

MemoClaw uses wallet-based identity. Set MEMOCLAW_PRIVATE_KEY (hex string with 0x prefix) so the client can sign free-tier auth headers and x402 payments. 
export MEMOCLAW_PRIVATE_KEY=0xyourprivatekey
Every wallet gets 100 free paid-endpoint calls. After that, calls fall back to x402 payments (0.005–0.005–0.01 per request depending on the endpoint).

​
Initialize the client

import { MemoClawClient } from "memoclaw";

const client = new MemoClawClient({
  // optional overrides
  // baseUrl: "http://localhost:8787",
  // privateKey: "0x...", // defaults to MEMOCLAW_PRIVATE_KEY
});

​
Quick Example

1

Store a memory

const created = await client.store({
  content: "User prefers dark mode and vim keybindings",
  importance: 0.8,
  metadata: { tags: ["preferences", "editor"] },
});
console.log(created.id);
2

Recall memories

const memories = await client.recall({
  query: "editor preferences",
  limit: 5,
});

for (const m of memories.memories) {
  console.log(`[${(m.similarity * 100).toFixed(0)}%] ${m.content}`);
}
Output:
[87%] User prefers dark mode and vim keybindings
3

Update and delete

await client.update(created.id, { importance: 0.95 });
await client.delete(created.id);

​
Ingest a conversation

Extract facts automatically from conversation history and auto-create relations. 
const result = await client.ingest({
  messages: [
    { role: "user", content: "I prefer dark mode and use vim. My timezone is PST." },
    { role: "assistant", content: "Got it! I'll remember those preferences." },
  ],
  auto_relate: true,
});

console.log(
  `Extracted ${result.facts_extracted} facts, created ${result.relations_created} relations`,
);

​
Error handling

import { MemoClawClient, MemoClawError } from "memoclaw";

const client = new MemoClawClient();

try {
  await client.delete("nonexistent-id");
} catch (err) {
  if (err instanceof MemoClawError) {
    console.log(`Error ${err.status}: ${err.message}`);
  }
}
