## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability domains-rapidruntime-com-register-a-new-domain-0441b56b -d '<json body>'
```

Example prompt: Register morningbloomcoffee.com for 2 years using my contact info: Jane Doe, 123 Main St, Austin, TX 78701, US, jane@morningbloom.com, +1.5125550100.

## When to prefer this

Use this endpoint when you need to register a domain name that has been confirmed available (via the check availability endpoint). It handles privacy protection, autorenew, and transfer lock automatically, and applies a single contact for all WHOIS roles, making it ideal for streamlined one-shot domain registration workflows.

## Known failure modes

- Domain already registered or not available — registration blocked
- Invalid or incomplete contact information — validation error returned
- Unsupported TLD — domain extension not available through this registrar
- Payment/billing failure — transaction not completed
- years out of range (must be 1–10) — schema validation error
- Domain name format invalid — rejected before processing

## How this service works

Register a domain name. Check availability first to confirm pricing. Provide contact info — it will be used for all WHOIS roles (registrant, admin, tech, billing). Privacy, autorenew, and lock are enabled by default.

## Output

Returns the registered domain object (domain name, lock status, autorenew flag, creation date, expiry date, WHOIS contacts for all four roles) plus the order number and total amount paid.
