## 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 x402-toolbox-dns-txt-records-lookup-1edee20c
```

Example prompt: Can you look up the DNS TXT records for example.com? I want to see SPF, DKIM, and any verification tokens.

## When to prefer this

Choose this endpoint when you need a quick, no-signup, pay-per-call DNS TXT record lookup billed in USDC via the x402 protocol. It is ideal for AI agents that need to verify domain ownership, check email authentication policies (SPF/DKIM/DMARC), or confirm DNS-based tokens without managing API keys or subscriptions.

## Known failure modes

- Domain does not exist — returns empty records or DNS NXDOMAIN
- Invalid domain format supplied — may return an error response
- Payment failure over x402 — returns 402 Payment Required if USDC payment is rejected
- Network timeout resolving DNS — may return an error or empty result
- No TXT records exist for the domain — returns empty list

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object indicating success (ok: true, paid: true) along with the DNS TXT record values associated with the queried domain, including strings like SPF policies, DKIM keys, ownership verification tokens, and DMARC policies.
