## 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 klymax402-dns-lookup-api-79f78291
```

Example prompt: Can you look up the MX records for gmail.com so I can see what mail servers Google uses?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call DNS lookup without managing API keys or infrastructure. Ideal for AI agents that occasionally need to resolve or verify DNS records across multiple types (A, MX, TXT, CNAME, etc.) without subscribing to a dedicated DNS API service. At $0.005 per call via USDC on Base, it suits low-to-medium frequency lookups where simplicity and no-key access matter.

## Known failure modes

- Domain does not exist — returns empty records array or NXDOMAIN error
- Invalid DNS record type specified — may return error or default to A record
- Network/resolver timeout — elevated query time or timeout error
- Malformed domain input — returns validation error
- DNS propagation delay — records may not reflect recent changes

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object containing the queried domain, DNS record type, an array of matching DNS records, the resolver used, and the query time in milliseconds.
