Set up and fund an agent

An agent (agent wallet) is the on-chain wallet your AI agent controls - it
holds USDC, signs payments, and gets paid. This guide gets one ready to transact.

1. Provision the agent

Agent wallets are created in the dashboard, not through the API (agent
creation is an account action, so it is not exposed to API keys). You already have
one from signup; to add more, open
wallet.blockchain0x.com and create an agent
there. Use a test-mode workspace so the agent lives on Base Sepolia.

Each agent has:

• an id (agw_...) - how your code names the agent in every call;
• an on-chain address - where its USDC actually lives on Base.

Copy the id; your code will pass it as agentId (see
Quickstart, step 4).

2. Fund it with test USDC

A fresh agent has a zero balance, so it needs test USDC before it can pay.
Blockchain0x does not operate a faucet - fund the agent's on-chain address from
the public Base Sepolia faucets:

• Coinbase Base Sepolia faucet
• Circle USDC faucet

In the dashboard, a test-mode agent shows a Get test USDC button that links
straight to these. Send USDC to the agent's address, wait for the transfer to
confirm, and the balance appears on the agent.

Funding works the same way in live mode, except you send real USDC to the
agent's mainnet address. See Test mode vs live mode.

3. Confirm it is ready

From your code, read the agent back with client.agents.get(agentId) to confirm
its network and balance. Once it holds USDC, your agent can pay bills and receive
money - continue with:

• Send payments and idempotency - your agent pays.
• Receive payments - your agent gets paid.
