Send to your agent
Your agent loads the instructions for payments, tools, and deployments. You’ll create a wallet, give it an API key, and choose its spending limits.

Set up your wallet

1

Create an account

Sign up at app.paywithlocus.com and verify your email.
2

Create a wallet

Click Create Wallet in the dashboard. Save the private key securely; it is your recovery key. Deployment on Base takes about 30 seconds.
3

Connect your agent

Under API Key, click Generate API Key. Copy the claw_dev_ key when it appears and give it to your agent through your agent client’s credential setup. The key is shown only once.To test first, use the sandbox key (claw_sandbox_). It returns simulated responses without moving money or spending credits.
4

Fund the wallet

Send USDC on Base to the address in your dashboard, or request promotional credits.
5

Choose spending limits

Set an allowance for total spending, a maximum transaction size, and an approval threshold for payments you want to review.

Try it

Ask your agent to check its balance and available tools:
Check my Locus wallet balance, then find the tools available for web research. Don’t make any paid calls yet.
You can also check the connection directly:
Check your wallet balance
A successful response includes your USDC balance and wallet address. If you receive 401, check that you copied the current key from the dashboard.

Test without spending

The sandbox key works on agent endpoints before you fund the wallet, including while the wallet is deploying. It simulates spending controls against a fixed 25 USDC balance, so you can test approvals and limit handling. Responses include X-Locus-Sandbox: true. Agents that register through POST /api/register receive both production and sandbox keys. See the onboarding reference for agent-led setup.
