How this service works
TLD info / top-level domain registry lookup / ccTLD vs gTLD / TLD introduction year / new gTLD registry. For any top-level domain, returns the registry operator, type (gTLD / ccTLD / sTLD), country (for ccTLDs), introduction year, and notes. In-handler dictionary covers ~80 of the most common TLDs; falls back to a structural guess for unrecognized TLDs.
Output
Returns an object containing the registry operator name, TLD type classification (gTLD, ccTLD, or sTLD), country name for ccTLDs, year the TLD was introduced, and any relevant notes. Covers ~80 common TLDs from an in-handler dictionary with structural fallback guesses for unrecognized TLDs.
Example use cases
Example prompt
“What's the registry operator for .io, is it a ccTLD or gTLD, which country does it correspond to, and when was it introduced?”
Technical details
Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/tld-infoWhen to prefer
Use this endpoint when you need quick structured metadata about a TLD — its type, registry, country, or introduction year — without scraping IANA or performing complex DNS lookups. Best for informational queries about well-known TLDs; note that obscure TLDs fall back to guesses rather than authoritative IANA data.
Side effects
- Unrecognized or obscure TLD returns a structural guess rather than authoritative data
- Missing or malformed TLD input returns a validation error
- New gTLDs not yet in the dictionary may return incomplete or estimated information
- Network or worker timeout on the Cloudflare edge
