# is-dns-hosted-by-ovh

> is-dns-hosted-by-ovh is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Checks whether a domain's DNS is hosted by OVH by looking up its NS records via Cloudflare DoH and matching against OVH nameserver patterns, returning a yes/no answer plus matched nameservers.

## 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 is-dns-hosted-by-ovh-6e699aa9
```

Example prompt: Can you check if example.com has its DNS hosted by OVH — I need to know the nameservers and whether any of them match OVH's patterns?

## When to prefer this

Use this endpoint when you need a cheap, fast, single-domain check specifically for OVH DNS hosting detection, such as during sales prospecting, pre-migration audits, or vendor security mapping. Prefer it over general NS lookup tools when you need an opinionated yes/no answer with matched nameserver attribution for OVH specifically, without building your own pattern-matching logic.

## Known failure modes

- Domain does not exist or has no NS records — returns no match with empty nameserver list
- DNS lookup timeout or Cloudflare DoH unavailability — request may fail or return error
- Malformed domain name input — validation error returned
- OVH uses new nameserver patterns not yet in matcher — false negative possible
- Rate limiting or payment failure — 402 or request rejection

## How this service works

Is the domain's DNS hosted by ovh? Looks up the NS records (Cloudflare DoH) and matches them against ovh's nameserver patterns, returning yes/no, the nameservers and which ones matched. Vendor detection for sales, migration and security work. $0.01 per lookup.

## Output

Returns a boolean yes/no indicating whether the domain's DNS is hosted by OVH, the full list of NS records discovered via Cloudflare DoH, and a subset listing specifically which nameservers matched OVH's known patterns.
