# Hyrule Cloud DNS Blocklist Check

> Hyrule Cloud DNS Blocklist Check is a paid API for AI agents from cloud.hyrule.host, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-17).

Checks whether a domain is listed on any of 16+ DNS blocklists/filter lists and returns per-source verdicts with categories

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 hyrule-cloud-dns-blocklist-check-187d280c -d '<json body>'
```

Example prompt: Can you check whether example.com is listed on any DNS blocklists or ad filter lists like EasyList right now?

## When to prefer this

Use this endpoint when you need a comprehensive, multi-source DNS blocklist check (16+ sources) against recognized filter lists like EasyList, rather than a single-list lookup or a reputation API. Ideal for verifying domain safety before email delivery, API integration, or content display, particularly when you need per-source evidence and category labels rather than just a pass/fail score.

## Known failure modes

- Invalid or malformed domain input returns validation error
- Blocklist source temporarily unavailable may cause partial results (partial: true in response)
- Domain exceeding 253 characters rejected
- Network timeout fetching one or more sources may degrade result completeness

## How this service works

Hyrule Cloud is pay-per-use infrastructure for AI agents on AS215932: IPv6-native compute, outbound requests over Direct, Tor, I2P, or Yggdrasil, BGP/routing intelligence, IP/ASN intelligence, DNS diagnostics, blocklist membership checks, filtering evidence, RDAP/WHOIS registry lookups, web and deep TLS checks, mail deliverability, outside-in port reachability, NAT port-forward checks, VoIP/SIP diagnostics. Calls settle in USDC via x402. Domain registration is deferred from this launch catalog. This OpenAPI document contains the launch-ready, independently payable agent surface plus the free supporting routes (quotes, status polling, pricing, template catalog) required to complete those workflows.

## Output

Returns a verdict ('not_listed' or 'listed'), a list of results per blocklist source with outcome, source name, source status, age, and matched categories, plus aggregate counts of how many sources were checked and matched, a normalized domain, and a snapshot ID for audit purposes.
