tools
buy_domain
Start the purchase flow for an available domain via Stripe checkout.
IMPORTANT: Before calling this tool, you MUST first call check_domain
to get the price, then clearly show the user the price and get their
explicit confirmation before proceeding. Never call buy_domain without
the user seeing and approving the price first.
The registrant contact details are required because the domain will be
registered in the buyer's name (they become the legal owner). WHOIS
privacy is enabled by default, so these details are not publicly visible.
Creates a Stripe checkout session. IMPORTANT: After this tool returns,
you MUST open the checkout_url by running the shell command
`open "<checkout_url>"` (macOS/Linux) so the payment page launches
automatically in the user's default browser. Do NOT paste the URL as
a link. Tell the user the page has been opened and they can complete
payment there.
Args:
domain: The domain to purchase (e.g. "coolstartup.com").
first_name: Registrant's first name.
last_name: Registrant's last name.
email: Registrant's email address.
address1: Registrant's street address.
city: Registrant's city.
state: Registrant's state or province.
postal_code: Registrant's postal/zip code.
country: 2-letter ISO country code (e.g. "US", "GB", "DE").
phone: Phone number in format +1.5551234567.
org_name: Organization name (optional, leave empty for individuals).
Returns:
Dict with order_id, checkout_url, price_cents, and price_display.
Input schema
{'type': 'object', 'required': ['domain', 'first_name', 'last_name', 'email', 'address1', 'city', 'state', 'postal_code', 'country', 'phone'], 'properties': {'city': {'type': 'string'}, 'email': {'type': 'string'}, 'phone': {'type': 'string'}, 'state': {'type': 'string'}, 'domain': {'type': 'string'}, 'country': {'type': 'string'}, 'address1': {'type': 'string'}, 'org_name': {'type': 'string', 'default': ''}, 'last_name': {'type': 'string'}, 'first_name': {'type': 'string'}, 'postal_code': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
buy_domain_crypto
Start the purchase flow for a domain using USDC crypto payment (x402 protocol).
Autonomous two-step payment flow â no browser required:
Step 1: Call this tool to reserve the domain and get a pay_url.
Step 2: Pay the pay_url using your x402 wallet:
- If you have Coinbase Payments MCP: call its x402 payment tool with the pay_url.
- Otherwise: run `curl -L <pay_url>` â your x402-enabled HTTP client will handle
the 402 handshake and USDC payment on Base automatically.
After payment succeeds, call get_domain_status(order_id) to poll until
registration is complete (usually under 60 seconds).
The registrant contact details are required because the domain will be
registered in the buyer's name (they become the legal owner). WHOIS
privacy is enabled by default, so these details are not publicly visible.
IMPORTANT: Before calling this tool, you MUST first call check_domain
to get the price and confirm it with the user.
Args:
domain: The domain to purchase (e.g. "coolstartup.com").
first_name: Registrant's first name.
last_name: Registrant's last name.
email: Registrant's email address.
address1: Registrant's street address.
city: Registrant's city.
state: Registrant's state or province.
postal_code: Registrant's postal/zip code.
country: 2-letter ISO country code (e.g. "US", "GB", "DE").
phone: Phone number in format +1.5551234567.
org_name: Organization name (optional, leave empty for individuals).
Returns:
Dict with order_id, pay_url (full URL to pay via x402),
price_usdc, price_cents, network, and USDC contract address.
Input schema
{'type': 'object', 'required': ['domain', 'first_name', 'last_name', 'email', 'address1', 'city', 'state', 'postal_code', 'country', 'phone'], 'properties': {'city': {'type': 'string'}, 'email': {'type': 'string'}, 'phone': {'type': 'string'}, 'state': {'type': 'string'}, 'domain': {'type': 'string'}, 'country': {'type': 'string'}, 'address1': {'type': 'string'}, 'org_name': {'type': 'string', 'default': ''}, 'last_name': {'type': 'string'}, 'first_name': {'type': 'string'}, 'postal_code': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
buy_domain_mpp
Start the purchase flow for a domain via Stripe's Machine Payments Protocol (MPP).
MPP lets autonomous agents pay with fiat (cards, Link) or stablecoins via
Shared Payment Tokens, with no browser checkout. Two-step flow:
Step 1: Call this tool to get an order_id and pay_url.
Step 2: Make an HTTP GET request to the pay_url with an MPP-enabled HTTP
client. The server responds with HTTP 402 + WWW-Authenticate; the client
creates a Shared Payment Token and retries with an Authorization header.
The server charges the SPT through Stripe and kicks off domain registration.
After payment, call get_domain_status(order_id) to poll until complete.
Requires: An MPP-compatible client configured to mint SPTs against the
server's advertised Stripe Business Network profile.
Args:
domain: The domain to purchase (e.g. "coolstartup.com").
first_name: Registrant's first name.
last_name: Registrant's last name.
email: Registrant's email address.
address1: Registrant's street address.
city: Registrant's city.
state: Registrant's state or province.
postal_code: Registrant's postal/zip code.
country: 2-letter ISO country code.
phone: Phone number in format +1.5551234567.
org_name: Organization name (optional).
Returns:
Dict with order_id, pay_url (full URL), price_cents, price_display,
network_id, and payment_method_types.
Input schema
{'type': 'object', 'required': ['domain', 'first_name', 'last_name', 'email', 'address1', 'city', 'state', 'postal_code', 'country', 'phone'], 'properties': {'city': {'type': 'string'}, 'email': {'type': 'string'}, 'phone': {'type': 'string'}, 'state': {'type': 'string'}, 'domain': {'type': 'string'}, 'country': {'type': 'string'}, 'address1': {'type': 'string'}, 'org_name': {'type': 'string', 'default': ''}, 'last_name': {'type': 'string'}, 'first_name': {'type': 'string'}, 'postal_code': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
check_domain
Check if a domain is available for purchase and get its price.
Always call this before buying. After showing the price, ask the user
two things before proceeding:
1. Confirm they want to purchase at that price.
2. Which payment method they prefer:
- "card" / "Stripe" â call buy_domain (opens Stripe checkout in browser)
- "crypto" / "USDC" / "x402" â call buy_domain_crypto (autonomous USDC payment,
no browser; requires Coinbase Payments MCP or another x402 wallet)
- "MPP" / "agent pay" â call buy_domain_mpp (Stripe agent payments via
Shared Payment Token, no browser)
If the user has Coinbase Payments MCP configured in their session, suggest
crypto as the default. Otherwise default to buy_domain (Stripe).
Args:
domain: The full domain name to check (e.g. "coolstartup.com").
Returns:
Dict with availability status, price in cents, and formatted price.
Input schema
{'type': 'object', 'required': ['domain'], 'properties': {'domain': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
