Tanod dnspeek Domain Availability is a paid API for AI agents from tanod.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).
Checks whether one or more domain names are available for registration using RDAP and DNS lookups
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Returns a JSON object with per-domain results including status ('available', 'registered', or unknown), a human-readable note, evidence showing RDAP HTTP status and whether NS records were found, plus aggregate counts of available/registered/unknown names and a disclaimer noting that registrar confirmation is needed before purchase.
POSThttps://tanod.dev/v1/domain/availability?utm_source=zero.xyzUse this endpoint when you need a quick, no-signup programmatic check of domain availability using authoritative RDAP data and DNS fallback, especially for bulk checks of up to 50 names at once or for internationalized (Unicode/IDN) domain names. It is pay-per-call with no subscription required, making it ideal for agent workflows that only occasionally need domain lookups. Prefer a registrar API if you need guaranteed accuracy for premium/reserved names or need to initiate a purchase.
| Field | Type | Description |
|---|---|---|
| name | — | One domain name to check. Send this or `names`. |
| names | — | 1-50 domain names to check, such as example.com or bücher.de (Unicode names are converted to their xn-- form). Priced per name. An invalid name makes the whole call a 422 (not charged). Send this or `name`. |
