## 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 agentshelf-rdap-lookup-75f67bb2 -d '<json body>'
```

Example prompt: Can you pull the RDAP record for github.com so I can see who registered it, when it expires, and what nameservers it's using?

## When to prefer this

Use this endpoint when you need a structured, machine-readable RDAP record for a public domain name — especially when you need registration dates, registrar identity, nameservers, or domain status in a consistent JSON format. Prefer the free sandbox endpoint (POST /v1/sandbox/rdap) for testing before paying $0.005 USDC per live call.

## Known failure modes

- Private or reserved hostnames are blocked and return an error
- Invalid or malformed hostname returns a validation error
- Domain not found in RDAP registry returns a not-found response
- Network timeout if upstream RDAP registry is slow
- Payment failure if USDC balance is insufficient

## How this service works

Call when an agent needs a structured RDAP record for a public hostname (private names blocked). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/rdap first.

## Output

A structured RDAP (Registration Data Access Protocol) record for the queried hostname, including registrar name, registration and expiry dates, domain status codes, nameservers, and contact handle references where publicly available. Private/reserved hostnames are blocked.
