How this service works
Call when an agent needs TXT at _atproto. An empty answer is records: [] and is billed. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/dns-txt-atproto first.
Output
Returns an object containing a 'records' array of strings found in the DNS TXT record at the _atproto subdomain of the given hostname. An empty array (records: []) is returned when no such record exists; this result is still billed.
Example use cases
Verify Bluesky custom domain handle
“Check whether syntexa.ch has an _atproto TXT record set up so I can confirm the Bluesky custom domain handle is properly configured.”
Resolve AT Protocol DID for a domain
“What DID does the _atproto TXT record at alice.example.org point to? I need to verify her AT Protocol identity.”
Audit multiple domains for atproto setup
“Look up the _atproto DNS TXT record for mybrand.io — I need to know if the AT Protocol handle delegation is live before I announce our Bluesky presence.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-txt-atproto?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically resolve the AT Protocol DID for a given domain via DNS TXT lookup (the _atproto handle verification mechanism used by Bluesky). Prefer the free sandbox endpoint POST /v1/sandbox/dns-txt-atproto for testing or when no real DNS resolution is needed. Choose this paid endpoint for production live DNS queries against real hostnames.
Side effects
- Hostname does not exist in DNS — returns records: []
- No _atproto TXT record configured for the hostname — returns records: []
- Malformed hostname input — validation error
- DNS lookup timeout or upstream resolver failure
- Empty result billed at full $0.009 USDC regardless
