# has-anthropic-domain-verification

> has-anthropic-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 an Anthropic domain-verification TXT record by querying apex DNS records via Cloudflare DoH, returning presence status and truncated token value.

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-anthropic-domain-verification-bc144d10
```

Example prompt: Can you check if example.com has an Anthropic domain verification TXT record — I want to know if they're a verified Anthropic customer?

## When to prefer this

Use this endpoint when you need to determine whether a specific domain has completed Anthropic's domain verification process, indicating that the company is likely an Anthropic customer or has set up Anthropic's products. Prefer this over manual DNS lookups or generic TXT record endpoints when you specifically need Anthropic verification detection with structured output.

## Known failure modes

- Domain does not exist or has no TXT records — returns absence/not-found status
- Cloudflare DoH query timeout or network error — may return an error response
- Invalid or malformed domain input — likely returns an error
- Domain has TXT records but no Anthropic verification token — returns not-verified result

## How this service works

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

## Output

Returns whether the Anthropic domain-verification TXT record is present at the apex of the queried domain, along with the truncated token value if found, indicating the domain owner has verified ownership with Anthropic.
