## 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-record-lookup-for-imap-imap-tcp-7e8bacd0 -d '<json body>'
```

Example prompt: What IMAP server and port does gmail.com advertise via its _imap._tcp SRV record?

## When to prefer this

Use this endpoint when you need to discover IMAP server configuration for a domain via DNS SRV records (_imap._tcp) as part of email client autoconfiguration or service discovery. Prefer the unpaid POST /v1/sandbox/dns-srv-imap endpoint first for testing. Choose this over manual DNS tools when an AI agent needs programmatic, structured SRV record data with x402 micropayment-based access.

## Known failure modes

- Domain has no _imap._tcp SRV record — returns empty or NXDOMAIN result
- Invalid or malformed hostname input — validation error
- DNS resolution timeout or upstream DNS failure — network error
- Hostname exceeds 253-character limit — schema validation failure
- Payment of exactly $0.007 USDC not provided — 402 Payment Required

## How this service works

Call when an agent needs SRV records at _imap._tcp.{hostname} for IMAP. The caller sends the registrable domain, not the underscored name. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-imap first.

## Output

Returns SRV record data for the _imap._tcp subdomain of the given hostname, including target server hostname, port, priority, and weight values as advertised in DNS.
