## 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-srv-via-opendns-063998f6
```

Example prompt: Can you look up the SRV records for _sip._tcp.example.com using OpenDNS and tell me the TTL, response code, and whether DNSSEC was validated?

## When to prefer this

Choose this endpoint when you specifically need SRV record resolution as answered by OpenDNS, especially when comparing resolver behavior across providers (e.g., OpenDNS vs Cloudflare vs Google), detecting DNS propagation lag, or checking if OpenDNS applies filtering or returns split-horizon answers for service-discovery records.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code
- Resolver fails to answer — returns SERVFAIL response code
- No SRV records found — empty record set with NOERROR
- Network or upstream OpenDNS service unavailable — request timeout or error
- Invalid domain input — malformed query rejected

## How this service works

SRV records for a domain as answered by OpenDNS (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.

## Output

Returns the SRV record set (priority, weight, port, target) for the queried domain as answered by OpenDNS, along with the TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether the resolver validated DNSSEC, and the resolver's answer time in milliseconds.
