How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the apex domain (e.g. 'delx.ai'), an integer count of labels, an ordered array of label strings (e.g. ['api','delx','ai']), and a schema identifier string for the response format.
Example use cases
Validate subdomain structure for routing
“I need to parse the hostname staging.app.mycompany.com — can you split it into its apex domain and individual labels so I can figure out the subdomain depth?”
Extract root domain from user-submitted URL
“A user submitted the host commerce.delx.ai — break it apart into its apex domain and label segments so I can categorize it correctly.”
Audit domain label count for DNS policy
“Check the host mail.internal.corp.example.org and tell me the apex domain, how many labels it has, and what each label is.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/domain-label?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call utility to decompose a hostname into its apex domain and ordered labels without any signup or subscription. Ideal for agents that encounter arbitrary hostnames at runtime and need structured label data on demand, especially when cost predictability ($0.001 USDC per call) and no-account-required access matter.
Side effects
- Invalid or missing 'host' field returns an error response
- Malformed hostnames (e.g. empty string, numeric-only) may produce unexpected label arrays
- Very long hostnames exceeding DNS limits may fail
- Payment failure (insufficient USDC balance) results in HTTP 402 before processing begins
