── Frequently Asked Questions ──
What is the Domain Registration API?
RobotDomainSearch's Domain Registration API returns instant registration links for any domain from Porkbun, Namecheap, and GoDaddy. It includes estimated pricing from Porkbun and works with any TLD. One request gives you direct registration links for all three registrars.
Does it actually register domains?
No. The API provides direct registration links to registrars where you can complete the purchase. This gives you choice of registrar and transparent pricing without RobotDomainSearch handling payment or registration directly.
Which registrars are supported?
Currently three registrars: Porkbun (with estimated pricing), Namecheap, and GoDaddy. Each response includes direct registration links for all three.
Do I need an API key?
No. RobotDomainSearch is free during beta with no API key required. You get 60 requests per minute with full access to all endpoints.
Does it include pricing?
Yes, estimated registration pricing from Porkbun is included when available. This covers most popular TLDs. Namecheap and GoDaddy links go directly to their registration pages where you can see current pricing.
Can I combine this with availability checking?
Absolutely. A common workflow is to check availability with /check first, then call /register for available domains to get registration links. Both endpoints are free and fast.
