## 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 postman-domain-verification-txt-record-checker-41395298
```

Example prompt: Can you check whether stripe.com has a Postman domain verification TXT record — I want to know if they're a Postman customer?

## When to prefer this

Use this endpoint when you need to determine whether a specific company or domain has claimed ownership in Postman's platform, as a signal of Postman product adoption. Ideal for sales intelligence, lead enrichment, tech stack analysis, or OSINT workflows targeting developer tooling adoption. Prefer this over general DNS TXT lookups when you specifically want the Postman verification signal rather than raw TXT record content.

## Known failure modes

- Domain not found or invalid — DNS lookup returns no records
- Domain has no TXT records at apex — returns not-verified result
- Cloudflare DoH request fails — upstream DNS resolution error
- Malformed domain input — query rejected or returns error
- Rate limiting or payment failure — request not processed

## How this service works

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

## Output

Returns whether a Postman domain-verification TXT record is present at the apex of the queried domain, along with the truncated token value if found. Absence indicates the domain has not been verified in Postman.
