# has-docker-domain-verification

> has-docker-domain-verification is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Checks whether a domain has a Docker ownership verification TXT record by querying apex DNS TXT records via Cloudflare DoH.

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 has-docker-domain-verification-88536298
```

Example prompt: Can you check if stripe.com has a Docker domain verification TXT record — I want to know if they're verified on Docker and what the token looks like?

## When to prefer this

Use this endpoint when you need to determine whether a specific domain has completed Docker Hub or Docker product domain verification, typically for tech stack intelligence, competitive research, or vendor assessment. Prefer this over generic DNS lookup tools when the specific signal you need is Docker ownership verification.

## Known failure modes

- Domain does not exist or has no TXT records — returns absence result
- Cloudflare DoH query timeout or network error
- Malformed domain input causing lookup failure
- Domain has TXT records but no Docker verification token — correctly reports absence

## How this service works

Does the domain carry a docker domain-verification TXT record? Reads the apex TXT records (Cloudflare DoH) and reports whether the docker ownership token is present and the token value (truncated). A present token usually means the company uses docker's product; absence means not verified there. $0.01 per lookup.

## Output

Returns whether a Docker domain-verification TXT record is present at the domain apex, along with the truncated token value if found. This indicates whether the company is verified with Docker's products.
