## 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 twilio-domain-verification-txt-record-checker-4f58ed08
```

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

## When to prefer this

Use this endpoint when you need to determine whether a specific company or domain uses Twilio as a communications provider, by inspecting DNS TXT records for Twilio's ownership verification token. Prefer this over scraping or manual DNS lookups when you need programmatic, per-domain Twilio usage signals at scale or as part of an enrichment pipeline.

## Known failure modes

- Domain does not exist — no TXT records returned
- Cloudflare DoH query timeout or unavailability
- Domain provided without required query parameter — missing input
- TXT records exist but none match Twilio's verification token format
- Token present but truncated value may be incomplete for downstream use

## How this service works

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

## Output

Returns whether a Twilio domain-verification TXT token is present at the domain's apex DNS records, along with the truncated token value if found. Absence indicates the domain is not verified with Twilio; presence suggests the company is a Twilio product user.
