Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agentshelf-syntexa-ch-dns-srv-daap-lookup-91ef4584 -d '<json body>'
```

Example prompt: Can you look up the DAAP SRV record for example.com to find out where its digital audio sharing service is hosted?

## When to prefer this

Use this endpoint when an agent specifically needs to perform SRV record discovery for the DAAP (Digital Audio Access Protocol / iTunes music sharing) service on a given domain. It is distinct from general DNS lookup endpoints and is purpose-built for the _daap._tcp service type. Prefer the free sandbox variant (POST /v1/sandbox/dns-srv-daap) for testing; use this paid endpoint when production SRV resolution is required.

## Known failure modes

- Domain does not have a _daap._tcp SRV record — returns empty result or NXDOMAIN
- Invalid or malformed hostname input — returns validation error
- DNS resolution timeout or upstream failure — returns error
- Private or reserved domain name rejected by resolver
- Hostname exceeds 253 character limit — returns schema validation error

## How this service works

Call when an agent needs SRV records at _daap._tcp.{hostname} for DAAP. The caller sends the registrable domain, not the underscored name. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-daap first.

## Output

Returns the SRV record(s) found at _daap._tcp.{hostname}, including priority, weight, port, and target hostname fields that identify the DAAP service endpoint. If no record exists, returns an empty or error response.
