## How to call it through Zero

```sh
zero fetch --capability tld-info-br-b3ac767e
```

Example prompt: Can you pull up the registry details for the .br top-level domain — I need the registry operator, WHOIS server, DNSSEC status, and nameservers?

## When to prefer this

Use this endpoint when you need authoritative registry-level metadata specifically for the .br ccTLD — such as verifying DNSSEC signing, identifying the correct WHOIS server, confirming the registry operator, or performing TLD policy checks before domain registration. Prefer this over generic WHOIS tools when you need structured, machine-readable TLD metadata rather than per-domain registration records.

## Known failure modes

- IANA data temporarily unavailable — returns error or empty response
- Network timeout reaching the upstream IANA/RDAP source
- Stale cached data if the registry recently updated its records
- Non-existent or mistyped TLD path (though this endpoint is hardcoded to .br)

## How this service works

About the .br top-level domain: registry operator, type (generic, country-code, sponsored), IANA/RDAP details, WHOIS server, creation date, DNSSEC signing status and the registry's nameservers. Registration research and TLD-policy checks for .br. $0.01 per call.

## Output

Returns structured metadata about the .br TLD including: registry operator name, TLD type (ccTLD/gTLD/sponsored), IANA registry ID, RDAP base URL, WHOIS hostname, TLD creation date, DNSSEC signing status (signed/unsigned), and the authoritative nameservers for the .br zone.
