# TLD Info Lookup

> TLD Info Lookup is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns RDAP server URL, DNSSEC signing status, and nameserver count for any top-level domain (TLD) from the IANA bootstrap file.

## Facts

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-lookup-40aa0585
```

Example prompt: Before I register a domain under .io, can you look up the TLD info — specifically which RDAP server handles it, whether the .io zone is DNSSEC-signed, and how many nameservers it has?

## When to prefer this

Use this endpoint when you need authoritative, structured metadata about a TLD before domain registration, during domain security investigations, or when building tooling that needs to discover the correct RDAP server for a given extension. Prefer this over manual IANA lookups when you need programmatic access with structured output including DNSSEC status and nameserver count in one call.

## Known failure modes

- Unknown or invalid TLD returns an error (e.g. querying a non-existent TLD extension)
- IANA bootstrap file may not contain entries for very new or experimental TLDs
- Network timeout fetching IANA bootstrap data
- Payment of $0.01 USDC required per call — missing or failed payment returns 402

## How this service works

TLD information: the registry's RDAP server from the IANA bootstrap file, whether the TLD zone is DNSSEC-signed, and its nameserver count. Understand any domain extension before registering or investigating. $0.01 per TLD.

## Output

Returns structured data about the specified TLD including: the IANA-bootstrapped RDAP server URL for that registry, a boolean indicating whether the TLD zone is DNSSEC-signed, and the integer nameserver count backing the TLD.
