How this service works
Call when an agent needs SRV records at _openpgpkey._tcp.{hostname} for OpenPGP key. The caller sends the registrable domain, not the underscored name. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-openpgp first.
Output
Returns the SRV record data found at _openpgpkey._tcp.{hostname}, including priority, weight, port, and target fields that indicate where OpenPGP keys for the domain can be retrieved.
Example use cases
OpenPGP key server discovery for email
“I need to find the SRV record for OpenPGP key discovery on protonmail.com — can you resolve the _openpgpkey._tcp DNS records for that domain?”
Verify OpenPGP DNS configuration
“Can you check whether tutanota.com has an _openpgpkey._tcp SRV record set up so I can confirm their OpenPGP key discovery is configured in DNS?”
Automate secure email setup for a domain
“Look up the _openpgpkey._tcp SRV records for my domain company.io so I can figure out which keyserver my email client should contact to retrieve recipients' OpenPGP public keys.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-openpgp?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover where to fetch OpenPGP public keys for a domain by querying its DNS SRV record at _openpgpkey._tcp. Prefer the free sandbox POST /v1/sandbox/dns-srv-openpgp endpoint for testing before committing the $0.01 USDC per call fee. Suitable for automating secure email workflows, verifying OpenPGP DNS configurations, or building email encryption tooling that requires key server discovery.
Side effects
- Domain has no _openpgpkey._tcp SRV record configured — returns empty or NXDOMAIN result
- Invalid or malformed hostname input — validation error
- DNS resolution timeout or upstream DNS failure — service error
- Hostname exceeds 253 characters — schema validation error
- Payment not provided or insufficient — 402 payment required response
