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 dns-srv-record-lookup-for-ldap-f2f9a533 -d '<json body>'
```

Example prompt: What are the LDAP SRV records for example.com? I need to find the LDAP server hostname and port for that domain.

## When to prefer this

Use this endpoint when an agent needs to programmatically discover LDAP server endpoints for a domain via standard DNS SRV record lookup, particularly in identity, directory, or authentication workflows that require dynamic LDAP server discovery rather than hardcoded configuration.

## Known failure modes

- Domain has no _ldap._tcp SRV records configured — returns empty or NXDOMAIN
- Invalid or malformed hostname input exceeding 253 characters
- DNS resolution timeout or upstream DNS failure
- Domain does not exist in DNS
- Payment of exactly $0.007 USDC not provided — x402 payment required

## How this service works

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

## Output

Returns the SRV record data for _ldap._tcp.{hostname}, including one or more records each containing priority, weight, port number, and the target LDAP server hostname, enabling clients to locate and connect to the domain's LDAP directory service.
