## 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 dns-lookup-api-crypto-technicals-x402-host-2b8daf19
```

Example prompt: Can you look up all the DNS records for github.com — I need to see the A records, MX records, nameservers, and any TXT records?

## When to prefer this

Use this endpoint when you need a pay-per-call, programmatic DNS record lookup without managing your own resolver infrastructure; particularly useful for AI agents operating via x402 micropayment flows on Base network.

## Known failure modes

- Domain does not exist — empty arrays or NXDOMAIN equivalent
- Invalid domain format in request — malformed input error
- Network timeout if upstream DNS resolver is slow or unreachable
- Rate limiting or payment failure via x402 protocol if USDC payment is not processed

## How this service works

Pay-per-call crypto technical analysis for AI agents (x402, USDC on Base). Daily trend regime, Donchian levels, ATR stops, signals and backtests computed with the code of a live trend-following bot from Binance spot klines.

## Output

A JSON object containing the domain queried plus arrays of DNS record values for A (IPv4 addresses), MX (mail exchange servers), NS (nameservers), and TXT (text records) entries.
