Your AI agent can use these tools to manage your wallet and make payments. You talk to your agent in natural language—the agent uses these tools behind the scenes.

​
Wallet tools

​
Get wallet address

Returns your wallet address. Try: 
What's my wallet address?

​
Get wallet balance

Shows your token balances (USDC, etc.). Try: 
What's my wallet balance?

How much USDC do I have?

​
Show wallet app

Opens the wallet interface where you can:
  • Sign in with email/OTP
  • Browse the Bazaar tab to explore x402 services, filter by category/price, and copy prompts
  • Add funds via Coinbase Onramp
  • View transaction history
  • Configure spending limits
Try: 
Show me my wallet

​
Check sign-in status

Checks if you’re signed in and provides next steps if not. Try: 
Am I signed in?
Note: This runs automatically when your agent starts.

​
Payment tools

​
List Bazaar resources

Discovers available x402 services (APIs, data sources, etc.) that your agent can pay for. Try: 
What x402 services are available?

List services for onchain token data
Returns: Service names, descriptions, pricing, and quality scores.

​
Get details about a resource

Gets full documentation for a specific service including API structure, parameters, and payment requirements. Try: 
Get details for the weather API
Note: Your agent calls this before making payments to understand how to use the service.

​
Make an x402 request

Makes an API call and handles payment automatically. This is how your agent pays for services. Try: 
Get the most up to date crypto and AI news

Scrape product reviews for iPhone 15
What happens:
  1. Agent discovers payment requirements
  2. Sends USDC payment
  3. Calls the API
  4. Returns results
Payment details:
  • Uses USDC on Base network
  • No gas fees (sponsored)
  • Must be within your spending limits

​
Check payment requirements for a resource

Checks what payment an endpoint requires without actually paying. Useful for non-bazaar services. Try: 
What does this API cost to use?
Note: For bazaar services, use bazaar_get_resource_details instead; it includes more info.

​
What agents CAN’T do

These features exist in the wallet UI, but agents cannot access them. Only you can:

​
Set spending limits

Configure max spend per call and per session in the wallet UI. Agents respect these limits but can’t change them.

​
Transfer funds

Send USDC to other addresses. Agents can only pay for x402 services, not send to arbitrary addresses.

​
Add funds

Use Coinbase Onramp to add USDC. Agents can’t initiate onramp flows.
