## 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-cname-records-lookup-77e78b1e
```

Example prompt: Can you look up the DNS CNAME records for api.example.com and tell me what canonical name it resolves to?

## When to prefer this

Choose this endpoint when you need a lightweight, no-signup DNS CNAME lookup paid by microtransaction rather than managing API keys or subscriptions. Ideal for AI agents that need on-demand DNS introspection without prior authentication setup, particularly in automated pipelines where per-call USDC payment via x402 is acceptable.

## Known failure modes

- Domain does not exist — empty or error result returned
- No CNAME record present for the domain (A/AAAA record only)
- Payment not fulfilled — 402 response requiring x402 USDC payment
- Malformed domain input — invalid schema parameter
- DNS resolution timeout or upstream failure
- Rate limiting or temporary worker unavailability

## 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 with ok and paid status flags, along with the resolved DNS CNAME record(s) for the queried domain, including the canonical name target the domain alias points to.
