# dns-txt-via-alidns

> dns-txt-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 2026-10-01).

Fetches TXT records for a domain using AliDNS (223.5.5.5) via DNS over HTTPS, returning records, TTL, response code, DNSSEC validation status, and resolver answer time.

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-txt-via-alidns-99100a17
```

Example prompt: What TXT records does AliDNS return for example.com — I want to see the records, TTL, and whether DNSSEC was validated?

## When to prefer this

Choose this endpoint when you specifically need to see how AliDNS (a major Chinese public resolver at 223.5.5.5) resolves TXT records for a domain — useful for detecting propagation lag to Chinese resolvers, identifying split-horizon DNS differences, or spotting filtering behavior. Prefer it over generic DNS lookups when the AliDNS perspective specifically matters, such as for services targeting users in China.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code
- AliDNS resolver fails to answer — returns SERVFAIL response code
- No TXT records configured for the domain — returns NOERROR with empty record set
- Network timeout reaching AliDNS 223.5.5.5 — may result in elevated answer time or error
- Invalid domain name format — likely returns an error or SERVFAIL

## How this service works

TXT 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 domain's TXT records as answered by AliDNS 223.5.5.5, including the record values, TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether DNSSEC validation was performed, and the resolver's answer latency in milliseconds.
