## 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-ns-records-lookup-4e9dc354
```

Example prompt: What are the nameservers (NS records) for github.com?

## When to prefer this

Use this endpoint when you need a quick, no-signup DNS NS record lookup for any domain and are operating in an x402-capable agent environment that can make micro-payments in USDC on Base. Prefer this over general-purpose DNS APIs when you want zero onboarding friction and pay-only-for-what-you-use pricing at $0.001 per call.

## Known failure modes

- Domain does not exist — empty or error NS record response
- Invalid or malformed domain input — may return an error object
- DNS query timeout if the upstream resolver is slow
- Payment failure if USDC/Base transaction is rejected — returns HTTP 402
- Schema parameter missing or unrecognized — may produce unexpected results

## 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

A JSON response containing the NS (nameserver) records for the queried domain, indicating which nameservers are authoritative, along with ok and paid status flags confirming the x402 payment was accepted.
