## How to call it through Zero

```sh
zero fetch --capability ai-rook-domain-lookup-3263d0ea
```

Example prompt: Can you look up the DNS records for agents.ai-rook.com — I want to see the A records, MX records, nameservers, and when the SSL certificate expires?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call DNS and SSL lookup without API key setup, especially within an agentic workflow already using x402/USDC micropayments on Base. Ideal for one-off infrastructure checks or enriching domain data in automated pipelines where cost is $0.005 per call.

## Known failure modes

- Domain does not exist or is unresolvable — likely returns empty arrays or error
- Invalid domain name format — may return error or empty response
- DNS propagation lag — records may be stale
- SSL certificate not found or domain has no HTTPS — ssl_expires field may be null or absent
- Network timeout reaching authoritative nameservers

## How this service works

Live crypto trading intelligence for AI agents — real-time BTC signals, CVD, order flow, and active strategy setups, no API keys or signup. 43 pay-per-call endpoints total: trading data, AI inference (MiniMax M2.7 (456B-parameter Mixture-of-Experts)), web utilities, verification, and ERC-8183 ACP escrow with on-chain ERC-8004 reputation attestation (Agent ID 59646).
