# dns-a-via-alidns

> dns-a-via-alidns is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Resolves DNS A records for a domain using AliDNS (223.5.5.5) over HTTPS, returning records, TTL, response code, DNSSEC validation status, and answer latency.

## Facts

- Price: $0.01/call
- Payment: x402

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 dns-a-via-alidns-9dfb5ea3
```

Example prompt: What A records does AliDNS return for example.com, and does it validate DNSSEC? Also tell me the TTL and how fast AliDNS answered.

## When to prefer this

Choose this endpoint when you specifically need to see how AliDNS (Alibaba's 223.5.5.5 resolver) answers A record queries — particularly useful for checking DNS propagation in China-adjacent networks, comparing split-horizon behavior, verifying DNSSEC validation status on AliDNS, or benchmarking AliDNS answer latency against other resolvers like Cloudflare or Google.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code
- AliDNS temporarily unavailable — returns SERVFAIL
- Invalid or malformed domain name input — may return error or SERVFAIL
- Network timeout reaching AliDNS upstream — elevated latency or error response
- Payment not accepted — x402 payment required error before lookup proceeds

## How this service works

A records for a domain as answered by AliDNS 223.5.5.5 (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.

## Output

Returns the A records (IPv4 addresses) for the queried domain as answered by AliDNS 223.5.5.5, including TTL values, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the resolver performed DNSSEC validation, and the resolver's answer time in milliseconds.
