x402 agent wallets

Pay for Browser Use Cloud from an agent-native wallet: AgentCash (local wallet, MCP) or Coinbase’s Agentic Wallet (hosted wallet, CLI).

Give your agent a wallet with a few dollars of USDC in it, and it can run Browser Use tasks and pay as it goes. Pick a wallet:

AgentCash

A wallet that lives on your machine, built for coding agents: Claude Code, Cursor, Codex.

Coinbase Agentic Wallet

A wallet Coinbase hosts for you. Sign in with email, fund with Apple Pay or card, pay from the terminal.

Payments to Browser Use are credit top-ups, not per-call fees: each x402 payment ($5 default, $1 minimum) buys prepaid credit for a project tied to your wallet, and unused credit carries over. See pricing and credits.

AgentCash quickstart

AgentCash gives your coding agent a wallet and the tools to spend from it: check prices, pay for API calls, watch the balance. The wallet is a file on your machine.

1. Install the MCP server

   npx agentcash install
   

   The interactive installer detects your agent client. Or add it directly:

   claude mcp add agentcash --scope user -- npx -y agentcash@latest   # Claude Code
   codex mcp add agentcash -- npx -y agentcash@latest                 # Codex
   npx agentcash install --client cursor                              # Cursor
   
2. Fund the wallet

   The first run creates a wallet at ~/.agentcash/wallet.json. Get its deposit address and send it USDC on Base mainnet ($5 covers the default top-up; $1 is the minimum):

   npx agentcash@latest accounts
   

   Or just ask your agent — the list_accounts and get_balance tools do the same thing.

3. Run a browser task

   Prompt your agent:

   Use AgentCash to POST to https://x402.api.browser-use.com/api/v3/sessions
   with body {"task": "Go to example.com and tell me the page title"}.
   Pay the $1 minimum option. Then wait 60 seconds and GET
   /api/v3/sessions/{id} once to read the output — each request pays, so
   don't poll in a tight loop.
   

   The fetch tool handles the whole 402 → sign → retry loop. Use check_endpoint_schema first if you want to see the price and input schema without paying.

Coinbase Agentic Wallet quickstart

Agentic Wallet is a wallet Coinbase hosts for you, driven from the terminal with the awal CLI. Sign in with your email — no keys to manage — fund it with Apple Pay or a card, and pay for API calls with one command. The agentic-wallet-skills package teaches your coding agent the same commands.

1. Install and sign in

   npx skills add coinbase/agentic-wallet-skills   # optional: teach your agent
   npx awal auth login [e-mail]             # sends an OTP to your email
   npx awal auth verify 123456                     # paste the code
   npx awal status
   
2. Fund with USDC on Base

   npx awal show      # opens the wallet UI → Fund → Apple Pay / card / Coinbase
   npx awal balance
   

   Or send USDC on Base directly to the address from npx awal address.

3. Check the price, then pay

   npx awal x402 details https://x402.api.browser-use.com/api/v3/sessions
   

   shows our payment options ($5 default / $1 minimum, USDC on Base) and the task input schema, without paying. Then:

   npx awal x402 pay https://x402.api.browser-use.com/api/v3/sessions \
     -X POST -d '{"task": "Go to example.com and tell me the page title"}' \
     --max-amount 5000000 --json
   

   --max-amount is in atomic USDC units: 1000000 = $1.00.

4. Poll the session

   The response contains the session id. Poll https://x402.api.browser-use.com/api/v3/sessions/{id} until status is "stopped", then read output.

Which one?

	AgentCash	Coinbase Agentic Wallet
Wallet	Local file, self-custody	Coinbase-hosted, email OTP
Funding	Send USDC on Base to your address	Onramp (Apple Pay / card / bank) or direct USDC
Interface	MCP tools + CLI	CLI (+ skill for agents, MCP variant)
Best for	Autonomous coding agents	Humans who want fiat funding; CDP-ecosystem apps

Building a production app instead of driving a CLI? Use CdpX402Client from the CDP SDK (a CDP-managed server wallet) or bring your own x402 client.
