Suggest alternative free Dynamic DNS hostnames

API Docs with browser client
GET
/dns/ddns/free-hostnames/suggest

Suggest alternative labels available under a free Dynamic DNS parent domain, for when the requested one is taken or invalid. Returns bare LABELS, not full hostnames. Each is checked against the same rules a claim applies, but availability can still change before you claim.

Authorization

x-api-key<token>

In: header

Query Parameters

label*string
Length1 <= length <= 63
parentDomain*string
Match^[a-z0-9_]([a-z0-9-]{0,61}[a-z0-9_])?(\.[a-z0-9_]([a-z0-9-]{0,61}[a-z0-9_])?)*$

Header Parameters

x-namefi-eip7702-account?string

Optional delegated account address to authenticate as when the signer is an approved signer. Preferred header name.

x-namefi-eip1271-account?string

Legacy alias for x-namefi-erc1271-account. When multiple delegated account headers are present, x-namefi-eip7702-account takes precedence, then x-namefi-erc1271-account.

x-namefi-erc1271-account?string

Optional delegated account address to authenticate as when the signer is an approved signer. Preferred ERC-1271 header name.

Archive or restore a Dynamic DNS key PUT

Hide a dead Dynamic DNS key from the default list, or restore it. This is a display-only change: it never affects whether a key works. Only a key that has already been revoked (or invalidated by a domain transfer) can be archived — revoke it first.

Batch create DNS records POST

Create multiple DNS records in a single transaction. Requires domain ownership. All records will be validated together against DNS zone rules.
