## 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-a-records-lookup-f84bd5d2
```

Example prompt: What are the DNS A records for example.com — I need to see which IPv4 addresses it resolves to right now?

## When to prefer this

Choose this endpoint when you need a quick, no-signup DNS A record lookup and are comfortable paying $0.001 USDC per call via x402. Ideal for AI agent pipelines that need deterministic DNS resolution without managing API keys. Prefer over manual dig/nslookup when running in an automated, agent-driven environment that already supports x402 micropayments.

## Known failure modes

- Domain does not exist or has no A records — returns empty result or DNS NXDOMAIN
- Invalid or malformed domain name in schema parameter — likely returns error or empty response
- DNS propagation delay — recently updated records may return stale data
- Payment failure via x402 — call rejected before DNS lookup is performed
- Cloudflare Worker timeout if upstream DNS resolver is slow

## 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 object with ok and paid flags, along with DNS A record results for the queried domain — typically a list of IPv4 addresses that the hostname resolves to.
