# agentshelf.syntexa.ch DNS SRV IPP Lookup

> agentshelf.syntexa.ch DNS SRV IPP Lookup is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-23).

Looks up SRV records at _ipp._tcp.{hostname} for Internet Printing Protocol (IPP) service discovery given a registrable domain name.

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-ipp-lookup-5a316f04 -d '<json body>'
```

Example prompt: Can you look up the IPP SRV records for the domain printers.example.com so I can find out where the internet printing service is hosted?

## When to prefer this

Use this endpoint when an agent needs to programmatically discover IPP (Internet Printing Protocol) service endpoints via DNS SRV records for a given registrable domain. Prefer the free sandbox endpoint POST /v1/sandbox/dns-srv-ipp first during development or testing. Choose this paid endpoint for production lookups where the sandbox is unavailable or rate-limited.

## Known failure modes

- Hostname does not exist or has no _ipp._tcp SRV records — returns empty or not-found result
- Invalid or malformed hostname input (exceeds 253 chars or empty) — returns validation error
- DNS resolution timeout or upstream DNS failure — may return error or timeout
- Payment failure (insufficient USDC balance) — request rejected before processing

## How this service works

Call when an agent needs SRV records at _ipp._tcp.{hostname} for IPP. The caller sends the registrable domain, not the underscored name. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-ipp first.

## Output

Returns the SRV record details found at _ipp._tcp.{hostname}, typically including priority, weight, port number, and target hostname for the IPP printing service. If no SRV record exists, the response will indicate the absence of records.
