## 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 agent-tollgate-engine-dns-lookup-1d4031ae
```

Example prompt: Can you look up the A records for example.com using the DNS lookup tool?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call DNS resolution without setting up your own resolver infrastructure. Particularly useful in agent workflows that need to verify domain configuration, check propagation, or enrich domain data on demand. At $0.001 per call it is cost-effective for occasional lookups.

## Known failure modes

- Domain does not exist (NXDOMAIN) — empty answers array or error response
- Invalid record type requested — may return error or empty result
- Network timeout reaching upstream DNS resolver
- Malformed domain name input — validation error
- Rate limiting or payment failure via x402 protocol

## How this service works

50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.

## Output

Returns a JSON object with an 'answers' array containing DNS records, each with a TTL (time-to-live in seconds) and data field (the resolved record value such as an IP address, hostname, or string).
