# tld-info-sg

> tld-info-sg is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Returns registry metadata for the .sg country-code top-level domain, including operator, IANA/RDAP details, WHOIS server, creation date, DNSSEC status, and nameservers.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 tld-info-sg-f08ed495
```

Example prompt: Can you look up the registry details for the .sg top-level domain — I need to know who operates it, whether it's DNSSEC-signed, the WHOIS server, and what nameservers it uses?

## When to prefer this

Use this endpoint when you need authoritative registry-level metadata specifically about the .sg TLD itself — not individual .sg domain registrations. Prefer it over generic WHOIS clients when you need structured, machine-readable data about the TLD operator, DNSSEC policy, or RDAP/WHOIS server endpoints for Singapore domains.

## Known failure modes

- Network timeout reaching the upstream IANA or DNS data source — returns an error with no TLD data
- Upstream IANA registry data temporarily unavailable — may return stale or empty fields
- Invalid or unexpected query format — endpoint expects a simple GET with no parameters for the fixed .sg TLD

## How this service works

About the .sg 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 .sg. $0.01 per call.

## Output

A structured record containing: the .sg TLD's registry operator name, TLD classification (country-code), IANA identifier, RDAP base URL, WHOIS server hostname, creation date, DNSSEC signing status (signed/unsigned), and the authoritative nameservers delegated for the .sg zone.
