## 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 delx-commerce-rdap-domain-lookup-daabdc71 -d '<json body>'
```

Example prompt: Can you look up the RDAP registration details for stripe.com — I want to know the registrar, current status, and when it expires?

## When to prefer this

Choose this endpoint when you need structured, machine-readable RDAP data about a domain's registration status, registrar, and key dates — especially in agent workflows that require pay-per-call pricing with no signup, verifiable delivery, and USDC payment via x402. Prefer over traditional WHOIS when you need JSON-structured output rather than raw text.

## Known failure modes

- Domain not found in RDAP registry — returns empty or error result
- Timeout exceeded if registry responds slowly — configurable 1–15 second timeout
- Invalid domain format — malformed input may cause a validation error
- TLD not supported by RDAP — some legacy TLDs may lack RDAP coverage
- Network error reaching upstream RDAP registry — transient failure

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object containing the domain's RDAP handle, array of current statuses (e.g. 'active'), registrar name, registration date, and expiration date, plus the tool name identifier.
