Example use cases
Example prompt
“Register the domain 'morningbloom.ai' on Doma for me — my wallet is 0xAbCd1234567890abcdef1234567890abCDEF1234, and the registrant is John Doe, john.doe@morningbloom.ai, +1 4151234567, 1234 Market St, San Francisco, CA 94103, US.”
Technical details
Endpoint
POSThttps://mpp.doma.xyz/register?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to register a new domain name for a user who has an EVM wallet and wants to pay with USDC via blockchain. Prefer this over traditional registrars when operating in a Web3/crypto context or when an on-chain transaction record is required. Supports popular TLDs: .com, .xyz, .ai, .io, .net, .cash, .live, .fyi.
Side effects
- Domain already registered — registration fails with conflict error
- Unsupported TLD — domain pattern validation fails if TLD not in allowed list (com, xyz, ai, io, net, cash, live, fyi)
- Invalid EVM wallet address — 0x-prefixed 40-hex-character check fails
- Missing or incomplete contact information — required fields like email, phone, address not provided
- Insufficient USDC balance — payment transaction fails on-chain
- Network error or blockchain congestion — transaction submission times out
