💵 $0.01 USDC per call 🌐 Base 📈 8 calls / 30d · 2 unique payers

Add a new memory. This method is called every time the user informs anything about themselves, their preferences, or anything that has any relevant information which can be useful in the future conversation. This can also be called when the user asks you to remember something.

This endpoint speaks x402: an unpaid request returns HTTP 402 with machine-readable payment terms, your agent pays the $0.01 USDC in USDC on-chain, and retries automatically. Pays to 0x0cC2CDC0EB992860d6c2a216b1DC0895fD2DF82F.

const account = privateKeyToAccount(process.env.PRIVATE_KEY); // funds USDC on Base
const wallet = createWalletClient({ account, chain: base, transport: http() });
const fetchWithPay = wrapFetchWithPayment(fetch, wallet);

// Pays the $0.01 USDC automatically on the 402, then returns the real response:
const res = await fetchWithPay("https://staging.toolkit.dev/api/tool/memory/add-memory", { method: "POST" });
console.log(await res.json());
# pip install x402 eth-account httpx
import os, asyncio
from eth_account import Account
from x402.clients.httpx import x402HttpxClient

account = Account.from_key(os.environ["PRIVATE_KEY"])  # funds USDC on Base

async def main():
    async with x402HttpxClient(account=account) as client:
        # x402 handles the 402 -> pay ($0.01 USDC) -> retry automatically
        r = await client.get("https://staging.toolkit.dev/api/tool/memory/add-memory")
        print((await r.aread()).decode())

asyncio.run(main())
# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i -X POST "https://staging.toolkit.dev/api/tool/memory/add-memory" \
  -H 'content-type: application/json' \
  -d '{"content": {"description": "The content to store in memory", "required": true, "type": "string"}}'

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
