How this service works
Call when an agent needs SRV records at _http._tcp.{hostname} for HTTP. The caller sends the registrable domain, not the underscored name. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-http first.
Output
Returns the SRV records found at _http._tcp.{hostname}, including priority, weight, port, and target for each record entry. If no records exist, returns an empty or error result.
Example use cases
Service discovery for HTTP routing
“I need to find the SRV records for _http._tcp for the domain myservice.io — can you look those up so I know where to route HTTP traffic?”
Verifying HTTP SRV configuration
“Can you check whether the domain acmecorp.com has valid _http._tcp SRV records set up, and tell me what priority, weight, port, and target they point to?”
Debugging HTTP service location
“My HTTP client isn't connecting properly — can you pull the _http._tcp SRV DNS records for api.startupexample.com to see what host and port are advertised?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-http?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to perform DNS SRV record lookups specifically for the _http._tcp service type without setting up DNS resolution infrastructure. Prefer the unpaid POST /v1/sandbox/dns-srv-http endpoint for testing. Choose this over generic DNS libraries when the agent environment lacks DNS access or when a lightweight, pay-per-use HTTP-based lookup is preferred.
Side effects
- Domain does not exist or has no _http._tcp SRV records — returns empty or NXDOMAIN-style response
- Invalid hostname format — request rejected due to schema constraints (minLength 1, maxLength 253)
- Payment failure — x402 payment of $0.01 USDC not completed, request blocked
- Transient DNS resolution failure — upstream resolver unavailable
- Caller provides the full underscored name (_http._tcp.example.com) instead of just the registrable domain, which may cause unexpected results
