NAME

domain-availability — checks whether a domain is registered and returns registrar, registration date, expiry date, days_until_expiry, and current epp status flags

SYNOPSIS

POST https://x402.agentutility.ai/domain-availability
     Content-Type: application/json
     X-PAYMENT:    <signed-transferWithAuthorization>

     { ... }

↳ first call → 402 Payment Required. Sign USDCtransferWithAuthorization, retry with theX-PAYMENT header.

DESCRIPTION

Checks whether a domain is registered and returns registrar, registration date, expiry date, days_until_expiry, and current EPP status flags. Works for any TLD that supports RDAP (effectively all gTLDs and most ccTLDs). Backed by rdap.org, the public RFC-7480-compliant aggregator; 404s map to is_registered: false rather than an error. Use it as an RDAP lookup, WHOIS replacement, domain registration checker, or expiry date lookup.

OUTPUT — response shape

field	type	description

is_registered	string	Boolean indicating whether the domain has an active RDAP record; false when rdap.org returns 404.
registrar	string	Sponsoring registrar name from the RDAP record, or null if not disclosed by the registry.
status	string	Array of EPP status codes currently set on the domain, like clientTransferProhibited or pendingDelete.
registered_date	string	Original registration timestamp from the RDAP events array, in ISO 8601 format.
expires_date	string	Current expiration timestamp from the RDAP events array, in ISO 8601 format.
last_changed	string	Most recent modification timestamp from the RDAP events array, in ISO 8601 format.
days_until_expiry	string	Integer days between now and expires_date; negative if the domain has already expired.
source	string	Upstream data source identifier, typically rdap.org indicating which RDAP aggregator answered.

EXAMPLES — two ways to call

EXAMPLE 1 · curl

curl -X POST https://x402.agentutility.ai/domain-availability \
  -H 'Content-Type: application/json' \
  -d '{ }'

first response = 402 Payment Required with payment requirements; sign + retry with X-PAYMENT.

EXAMPLE 2 · mcp

# Install the MCP package for this endpoint's cluster
npx -y @agentutility/mcp-<cluster>

# Required: EVM private key with USDC on Base
export X402_PRIVATE_KEY=0x...

# Then call the domain-availability tool from your MCP-aware agent.

MCP server handles payment automatically — your coding agent just calls the tool by name.
