## 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 zeroclick-x402-service-registry-domain-register-rapidruntime-bf3f728e -d '<json body>'
```

Example prompt: I want to register mycoffeeshopmorningbloom.com for 2 years — can you check if it's available and register it with my contact email john@example.com as the WHOIS owner?

## When to prefer this

Choose this endpoint when you need a full-lifecycle domain management API — not just availability checks but also registration, renewal, DNS record management, nameserver updates, and WHOIS contact editing in a single RESTful API. Prefer over simpler domain-buy endpoints when you need programmatic DNS control or batch availability checks for up to 50 domains. The RapidRuntime backend is specifically suited for agents automating domain provisioning workflows.

## Known failure modes

- Domain already registered — availability check returns unavailable
- Invalid domain format — malformed TLD or domain string
- Batch limit exceeded — more than 50 domains submitted in one availability check
- Payment/credential failure — MPP credential invalid or insufficient funds
- WHOIS contact validation error — missing required registrant fields
- Nameserver not found or invalid — DNS propagation may fail

## How this service works

Full domain registration and management API by RapidRuntime. Search, register, renew, manage DNS records, nameservers, and WHOIS contacts. RESTful API with batch availability checks (up to 50 domains). Ownership tied to MPP credential.

## Output

Returns domain availability status, registration confirmation details, DNS record configuration, nameserver assignments, and WHOIS contact information depending on the operation performed.
