## How to call it through Zero

```sh
zero fetch --capability saas-verification-token-scanner-dc2ff04b
```

Example prompt: Look up the tech stack for acmecorp.com using DNS TXT verification tokens — I want to know which SaaS vendors they're using, like whether they're on Google Workspace or Microsoft 365, and if they use Salesforce, Slack, or Stripe.

## When to prefer this

Choose this endpoint when you need passive, non-intrusive tech stack intelligence derived purely from DNS — no website visit, no scraping, no detectable footprint. Ideal for high-volume B2B sales prospecting, lead enrichment, and market research. Prefer this over web scraping approaches when you need to respect robots.txt, avoid detection, or process many domains cheaply at $0.01 each. Best when the goal is identifying cloud SaaS adoption (Google Workspace, Microsoft 365, Salesforce, Slack, etc.) rather than frontend technologies like JavaScript frameworks.

## Known failure modes

- Domain does not exist or has no DNS TXT records — returns empty or error response
- Domain uses private/obfuscated DNS — tokens may be missing even if SaaS products are used
- Some SaaS products don't use DNS TXT verification — those vendors will not appear in results
- Rate limiting or DNS resolution timeouts may cause failures for unresponsive domains
- Misformatted domain input (e.g. including http://) may cause lookup failure

## How this service works

Which SaaS vendors a company uses, from DNS TXT verification tokens: Google Workspace, Microsoft 365, Apple, Facebook, Atlassian, Stripe, DocuSign, Adobe, Zoom, Slack, HubSpot, Salesforce, Shopify, OpenAI, Anthropic, Tailscale and more. Sales intelligence and tech-stack research without touching the website. $0.01 per domain.

## Output

A structured list of detected SaaS vendors and products associated with the queried domain, derived from DNS TXT verification tokens. Each identified vendor (e.g. Google Workspace, Microsoft 365, Salesforce, Slack, HubSpot, Stripe, DocuSign, Zoom, Shopify, Atlassian, Adobe, Apple, Facebook, OpenAI, Anthropic, Tailscale) is returned based on the presence of their corresponding ownership-verification TXT record in the domain's DNS. No website visit or scraping is required.
